Headings and emphasis

You can apply certain global classes to text objects to make the text easier to read for visually impaired users.

The following global classes are available to improve text readability for headings and blocks of text:

Heading 1 through 6
Tip: In HTML output, these classes are converted to <h1> to <h6> tags.
Emphasize Text and Strong Text
Tip: In HTML output, these classes are converted to <em> and <strong> tags.

You apply one of these global classes to text by accessing the Classes property of the text and choosing the class that you want to apply.
