The text control is fully adaptive to all screen sizes. You can also set a specific width and overwrite the default value. The resizing behavior depends on the settings that the apps use for the text.
You can define whether the text should wrap or directly truncate (property: wrapping).
You can also define how often the text should wrap before it truncates (property: maxLines).
For more information about the responsive behavior of text, see Wrapping and Truncating Text.
Note: The truncation indicator for multiple lines depends on the browser line clamping support. For browsers that support it, this will be shown as ellipsis (…), whereas in other browsers, the overflowing text will just be cut off.
