field--text.html.twig in Drupal 10

Default theme implementation for a text field.

A 'clearfix' class is added, because 'text' fields have a 'format' property that allows a Text Format to be associated with the entered text, which then applies filtering on output. A common use case is to align images to the left or right, and without this 'clearfix' class, such aligned images may be rendered outside of the 'text' field formatter's boundaries, and hence overlap with other fields. By setting the 'clearfix' class on all 'text' fields, we prevent that.

A 'text-formatted' class is added to assist with default styling of base elements such as paragraphs and lists that may not have classes assigned to them. This allows user entered content to have default styling without interfering with the styles of other UI components such as system generated lists or other dynamic content.
