You can create and apply themes to stylize an Adaptive Form. A theme contains styling details for the components and panels. Styles include properties such as background colors, state colors, transparency, alignment, and size. When you apply a theme, the specified style reflects on the corresponding components. Theme is managed independently without a reference to an Adaptive Form.
You can download and install AEM Forms reference content package from Software Distribution portal to import reference themes and templates to your environment.
A theme is created and saved as a separate entity, complete with meta-properties like Adaptive Forms. It allows reusing a theme in multiple Adaptive Forms. You can also move a theme to a different instance and reuse it.

Theme Editor is a business-user and web-designer/developer friendly interface that provides functionalities required to specify the styling of various Adaptive Form elements easily. When you create a theme, it is stored as a separate entity like forms .
The Theme Editor lets you customize styles of the components styled in a theme. You can customize how a form looks on a device.
The Theme Editor is divided in two panels:
Canvas - Appears on the right side. It shows a sample Adaptive Form in which all styling changes reflect instantly. You can also select objects directly from the canvas to look up styles associated with them, and to edit these styles. A device resolution ruler on the top governs the Canvas. Selecting a resolution breakpoint from the ruler shows the preview of the sample form for the respective resolution. Canvas is discussed in detail below.
Sidebar- Appears on the left side. It has the following items:
Selector: Shows the component selected for styling, and its properties that you can style. The selector represents all the components of a type. If you select a text box component in a theme for styling, all the text boxes in your form inherit the style. Selectors let you select a generic component or a specific component for styling. For example, a field component is a generic component, and a text box is a specific component.
Styling generic component:
A field can be a numeric box field, such as age, or a text box field, such as address.
When you style a field, all the fields such as age, name, address are styled.
Styling specific component:
A specific component impacts objects of the specific category. When you style the numeric box component in the theme, only the numeric box object in inherit the style.
For example, a text box field such as address which is longer and a numeric box field such as age is shorter. You can select a numeric box field, reduce its length, and apply to your form. Width of all numeric box fields is reduced in your form.
When you customize all the field components with a specific background color, all the fields such as age, name, and address inherit the background color. When you select a numeric box, such as age, and reduce its width, width of all the numeric boxes such as age, number of people in a family is reduced. Width of text boxes is not changed.
State: Lets you customize styles of an object in a specific state. For example, you can specify appearance of an object when it is in default, focus, disabled, hover, or error state.
Property Categories: Styling properties are divided in various categories. For example Dimension & Position, Text, Background, Border, and Effects. Under each category, you provide styling information. For example, under Background, you can provide Background Color, and Image & Gradient.
Advanced: Lets you add custom CSS to an object, which overrides the properties visual controls define if there is an overlap.
View CSS: Lets you view CSS of the selected component.
Also, in the Sidebar, at the bottom an arrow is present. When you click the arrow, you get two more options: Simulate Success and Simulate Error. These options, along with the options described above are discussed in detail below.
You can use a theme in multiple Adaptive Forms, which imports the component formatting that you have specified in the theme. You can style various components such as titles, description, panels, fields, icons, and text boxes. Use widgets to configure component properties in a theme. Prior knowledge of CSS or LESS is not required but desired, though the CSS Overrides section lets you write CSS code or provide custom selectors. The CSS Overrides section appears when you select a component in the sidebar.
Options in sidebar that let you select and style different components.
Clicking edit button against a component in the sidebar selects the component in Canvas, and lets you style the component using options in the sidebar.
Certain components like text box, numeric box, radio button, and check box are categorized under generic components like Field. For example, you want to customize styling of radio buttons. To select radio buttons for styling, select Field > Widget > Radio Button.
Themes in AEM Forms support styling of elements in the layout of panels in your forms. Styling of elements in out-of-the-box layouts and custom layouts is supported.
Out-of-the-box panels include:
Tabs on left
Tabs on top
Selectors vary for each layout.
Styling custom layouts from the Theme Editor involves:
Desktop and mobile layouts can have slightly or entirely different styles. For mobile devices, tablet and phone share similar layouts except for component sizes.
Use Theme Editor breakpoints to define alternate styling for different screen sizes. You can select a base device or resolution on which you start building the theme, and the styling variations for other resolutions are automatically generated. You can explicitly modify the styling for all the resolutions.
The theme is first created using a form, and then applied on different forms. The breakpoints used in theme creation can be different from the form on which the theme is applied. The CSS media queries are based on the form used in theme creation, and not the form on which the theme is applied.
When you select a component in the Canvas, its styling properties are listed in the sidebar. Select the object type and its state, and then provide its styling.
Theme editor caches up to ten styles applied to a component. You can use the cached styles with other component of a theme. Recently used styles are available right below the selected component in sidebar as a list box. Initially, the recently used styles list is empty.
As you style a component, the styles are cached and listed in the list box. In this example, the label of the text box is styled to change the font size and color. You can follow similar steps for choosing an image or changing colors to style a component. Observe how the style is cached and listed in the list box when the field label styling is changed.
In this example, style for the field label is changed, and when Responsive Panel Description is selected for style, a list entry is added in the asset library. The entry in the asset library can be used to change the style for Responsive Panel Description.
When a style is added in the asset library, it is available for other themes and in the style mode of the form editor UI. Similarly, when you use the style mode of the form editor UI to style a component, the style is cached and is available in themes.
The plus button against the asset library lets you permanently save the style with a name of that you provide. The plus button saves the style even if you do not click the Save button in the sidebar to apply the style to a component. The plus button to save a style for later use is not available in the style mode.
When you provide a custom name for a style, the style is tied to a theme and is no longer available to other themes. To delete a saved style:
On the CANVAS toolbar, click Theme Options > Manage Styles.
In the Manage Styles dialog, select a saved style, click Delete.
Modifications made in the styling are instantly reflected in the form loaded in the Canvas. Live preview lets you interactively define and see the impact of the styling. When you change the styling of a component, the Done button is enabled in the sidebar. To retain changes, use the Done button.
When an invalid character is entered in a field, the field boundary color changes to red and an error message is displayed at the top-left corner of the screen. For example, if you enter alphabets in a textbox which accepts numeric characters as inputs, the input box boundary color changed to red. You cannot save such a theme without resolving the error displayed at the center bottom of the screen.
When you create a theme, it is created with a form that is shipped with the Theme Editor. You provide styling for components in this form. Instead of the form that is shipped with the Theme Editor, you can select a form of your choice to provide styling and preview its results.
To replace the current form or in Theme Editor Canvas:
In the THEME EDITOR panel, click Theme Options > Configure.
In the General tab, browse and select a form for the Adaptive Form field.
You can undo or redo the undesired changes that occur accidentally. Use the redo/undo buttons in the Canvas.
Redo/undo buttons appear when you style a component in the Theme Editor.
The Theme Editor lets you edit a theme you created or uploaded. Navigate to Forms & Documents > Themes, and select a theme and open it. The theme opens in the Theme Editor.
As discussed above, the Theme Editor has two panels: Sidebar and Canvas.
Customizing the success state styling of Text Box Widget component in Theme Editor. Component is selected in Canvas, and its state is selected in the sidebar. Styling options available in the sidebar are used to customize the look of a component.
The theme is either created using the out-of-the-box form, or using a form of your choice. The Canvas shows the preview of the form or used for creating the theme with customizations specified in theme. The ruler above the form is used for determining the layout according to the size of the display of your device.
In the Canvas toolbar, you see:
Toggle Side Panel : Lets you show or hide sidebar.
Theme Options : Provides three options
Emulator : Emulates the look of your theme for different display sizes. A display size is treated as a breakpoint in the emulator. You can select a breakpoint and specify a style for it. For example, Desktop and Tablet are two breakpoints. You can specify different styles for each breakpoint.
When you select a component in the Canvas, you see the component toolbar on top of it. The component toolbar lets you select components, or switch to generic components. For example, you select a numeric text box in a panel. You see the following options in the component toolbar:
Numeric Box Widget: Lets you select the component to customize its look in sidebar.
Field Widget: Lets you select the generic component for styling. In this example, all text input components (text box/numeric box/numeric stepper/date input) are selected for styling.
: Lets you select the parent component for styling. If you select numeric box and tap this icon, field component is selected. If you select field component and tap this icon, panel is selected. If you keep tapping this icon for selection, you end up selecting the layout for styling.
The options available in the component toolbar vary based on the component you select.
The sidebar in theme editor provides options to customize styles for components in a theme, and use selectors. Selectors let you select a group of components or individual components, and you can search for selectors in the sidebar. You can write selectors for custom components.
When you select a component from the Canvas or selectors in sidebar, the sidebar shows all the options that let you customize styles for it.
Below are the options you see in the sidebar when you select a component:
A state is an indicator of user interaction with a component. For example, when a user enters erroneous data in a text box, the state of the text box changes to an error state. Theme editor lets you specify styling for a particular state.
Options for customizing state styles vary for different components.
Dimensions & Position
Lets you style alignment, size, positioning, and placing of components in the theme.
Your options are display setting, padding, margin, width, height, and Z Index.
You can also use the Layout mode to define the width of components using an easy drag-and-drop interface. For more information, see Use Layout mode to resize components.
Lets you customize the text styles in the component of the theme.
For example, you want to change how the text entered in the text box looks.
Your options are font family, weight, color, size, line height, text align, letterspacing, text indent, underline, italics, text transform, vertical align, baseline, and direction.
Lets you fill the background of the component with an image or a color.
Lets you choose how the border your component looks. For example, you want the text box to have a deep red, thick border with a dotted line.
Your options are width, style, radius, and color of the border.
Lets you add special effects to the components such as opacity, blend mode, and shadows.
Lets you add:
When you add a custom CSS code, it overrides the customization you added using the options in the sidebar.
Simulate Error and Success options are available at the bottom of the sidebar. You can see them using a show/hide arrow visible at the bottom of the sidebar. Using Theme Editor, you can style various states of a component.
For example, you add a numeric field in your form, and you specify its styling in theme editor. When a user types an alphanumeric value in the field, you want the background color of the text box to change. You select the numeric field in the theme, and use the state option in the sidebar. You select the Error state in the sidebar, and change the background color to red. To preview the behavior, you can use the Simulate Error option available in the sidebar. Simulate Error and Success options are described in detail below:
Lets you see how a component looks if you specify its styling for success state. For example, in a form, customers set password. Users can set password according to guidelines you provide. When a user types a password following all the guidelines you provide, the text box turns green. When the text box turns green, it is in success state. You can specify styling for a component in success state, and simulate its appearance using the Simulate Success option.
Lets you see how a component looks if you specify its styling for error state. For example, in a form, customers set password. Users can set password according to guidelines you provide. When a user types a password which does not follow all the guidelines you provide, the text box turns red. When the text box turns red, it is in error state. You can specify styling for a component in error state, and simulate its appearance using the Simulate Error option.
For example, in your form, you have two types of text boxes: one that accepts numeric values only, and other that accepts alphanumeric values. You can customize styling for the text box that accepts numeric values only (a numeric box).
To customize styling for a particular component (a numeric box in this example), perform the following steps:
In the Theme Editor, select the numeric box in the Canvas.
When you select the numeric box, you can see the component toolbar with three options:
Select Numeric Box Widget.
Sidebar title changes to Numeric Box Widget, and shows options to customize its look.
Use Dimension & Position option in the sidebar to customize size of the component. Ensure that the State is Default.
Instead of selecting Numeric Box Widget, select Field Widget in the component toolbar, and perform the steps above. When you select dimensions for Field Widget option, all the text boxes except the numeric box have the same size.
With component toolbar, you can also specify styling of components for its different states. For example, if a component is disabled, then it is in a disabled state. Commonly used states of a component that you can style in theme editor are: Default, Focus, Disabled, Error, Success, and Hover. You can select a component in the Canvas and use the State option in sidebar to customize its look.
To customize styling for a component in a specific state, perform the following steps:
When you customize the styling of a component after specifying its state, the customization appears for the component only for the specified state. For example, if you customize styling for the component when hover state is selected. The customization appears for the component when you move your pointer over the component in the rendered form to which you apply the theme.
To simulate behavior of states other than error and success, use Preview mode. To use Preview mode, click Preview in the page toolbar.
Use ruler in Canvas to select breakpoints for devices with smaller displays. Click emulator in Canvas to view ruler and breakpoints. The breakpoints let you preview a form for display sizes pertaining to different devices such as phones and tablets. Multiple display sizes are supported in Theme Editor.
To style components for different breakpoints:
You can style form components for multiple devices. Form components for desktops and mobile devices can have entirely different styles.
You can now use fonts available in a web-service in an Adaptive Form . Out-of-the-box, Adobe Fonts, Adobe’s web font service, is available as a configuration. To use Adobe Fonts, create a kit, add fonts in it, and obtain the Kit ID from Adobe Fonts.
To configure Adobe Fonts in Experience Manager, perform the following steps:
In the author instance, click Adobe Experience Manager > Tools > Deployment > Cloud Services.
On the Cloud Services page, navigate to and open the Adobe Fonts option. Open the configuration folder, and click Create.
On the Create Configuration dialog, specify a title for the configuration, and click Create.
You are redirected to the configuration page.
In the Edit Component dialog that appears, provide your Kit ID and click OK.
To configure a theme to use the Adobe Fonts configuration, perform the following steps:
On the author instance, open a theme in the theme editor.
In the theme editor, navigate to Theme Options > Configure.
In Adobe Fonts Configuration field, select a kit, and click Save.
Now, you can see that the fonts are added in the font-family property of the theme.
You can use the + button to add a font. When you add a font, it gets listed in the sidebar.
In addition to the theme configuration option, you can also add your font from the theme editor itself. Type the font you want to use in the font family field under sidebar and press the return key on your keyboard.
When you select a font, it is added under the font family list. You can use the Mask option in theme editor to disable or enable the listed fonts.
You can see the component font change.
The Font Family field supports multiple fonts. When you type a font, browser looks for it and applies it to the selected component. If the browser cannot find a font, it looks for a font that is next to it in the family. You can start with typing the specific font you are looking for. If you do not find the font you want to use, you can type a generic font in the family and use it.
You can mask styles applied in a theme. In the theme editor sidebar, you can use the icon to disable an applied style. For example, if you change dimensions of a component in a form , then you can use the mask button on the left of a property to disable it. When you save a theme, the selected masking options are retained.
The example below shows masked and unmasked styles in a theme.
To apply a theme to an Adaptive Form:
Open your form in edit mode. To open a form in edit mode, select a form and click Open.
In the edit mode, select a component, then click > Adaptive Form Container, and then click .
You can edit properties of your form in the sidebar.
In the sidebar, click Styling.
Select your theme from the Adaptive Form Theme drop-down and click Done .
You can also define a theme for an Adaptive Form when you are creating it.
A theme styles different components of a form. You can use the
themeOverride property to dynamically change theme of a form. A typical URL of a form is:
You can use the themeOverride parameter to apply a theme on the runtime.
themeOverride option lets you provide a path to a theme. It changes the theme of the form and refreshes the form with updated styles.
With AEM Forms, along with default out-of-the-box canvas theme, there are many other themes. If you want to design your form using other themes, along with more changes, copy the theme from Theme Library folder. Paste the copied themes outside the Theme Library folder, and edit the copied theme according to the changes you want.
To copy a theme, perform the following steps:
After you customize the theme, apply it to your form .
Do not modify the themes available in the Theme Library folder. This folder contains system themes. Any change you made to these themes are overwritten on installing a newer version or hot fix of AEM Forms.
When you select view CSS, Theme Editor collects all the styling information, and builds a CSS. It collects information in the following order:
For example, background color of a textbox is blue. You change it to pink using the properties in the sidebar. When you generate CSS, you see background color of the text box as pink. After changing the background color using the properties, another author uses CSS override option to change the background color text box as white. When you generate CSS, you see background color as white in the generated CSS.
When you specify styles for components in Theme Editor, a CSS is generated. When you style a generic component, multiple components included in it are also styled. For example, when you style a field, the text box and label in it are also styled. When you style the text box within the field, it gets its own CSS. If you want to debug the CSS generated for the field and the component, Theme Editor provides options that let you view CSS.
You can see the generated CSS using the following options:
Avoiding assets from another Theme
When you edit a theme, you can browse and add assets (such as images) from other themes. For example, you are editing the background of a page. For example, when you select Page > Background > Add > Image, you see a dialog that lets you browse and add images in other theme.
You can face issues with your current theme if an asset is added from another theme, and the other theme is moved or deleted. It is recommended that you avoid browsing and adding assets from other themes.
You can also create a theme, create copies of it, and then modify the styling provided in the copied themes for similar use-cases. See [Getting specific appearance using Themes](#specific-af-appearance)
The Theme Editor lets you create themes to style your form . You can specify styling of components in a theme, that enable consistency in look and feel among multiple forms you develop. Specifying styling information in a theme, and then applying the theme to a form is recommended.
You can style components using the Style mode in form multichannel editor when you work with a form. Using style mode to change form component styling overrides the styling specified in the theme. If you want to change styling for certain components of a particular form, see Inline styling of components.
Changing container panel layout width
Changing container panel layout width is not recommended. When you specify width of a container panel, it becomes static and does not adapt to different displays.
When to use form editor or theme editor for working with header and footer
Use theme editor if you want to style header and footer using styling options such as font style, background, and transparency.
If you want to provide information such as a logo image, company name in header, and copyright information in the footer, use the form editor options.
