Understanding Text Overlay Properties understanding-text-overlay-properties

Using the Text Overlay properties, you can add text to any of the components in your Screens project. The following section provides an overview of the properties that are available in Text Overlay:

text

You can add a text to the text box and add typographical emphasis such as bold, italics, and underline.

Color Variant This option allows the text to be either Dark (text in black color) or Light (text in white color).

Sizing & positioning This option lets the user align the text horizontally or vertically or also use fine-grained tools for text alignment.

NOTE
To properly use fine-grained tools, be sure to identify the correct position in pixels using (px) as a suffix, for example 200 px. The result of this expression is 200 pixels from start point.
