Text format
Drupal
Configuration that defines the processing that happens to user-entered text before it is shown in the browser. This might include stripping away or limiting HTML tags, turning URLs into links, turning text separated by a blank line into paragraphs, and so on. Text formats can be restricted to certain roles, so it's entirely possible, for example, to give trusted content editors a full rich text environment to create content, while anonymous visitors can only use simple styling like bold and italic to leave comments.
