CSS Injector information

For changing the appearance of content, you can use the CSS Injector module (Configuration → Development → CSS Injector). Some HTML attributes are stripped out by the WYSIWYG Filter module.

You can create a CSS Injector rule that you configure to only show on specific pages, or you can add a CSS rule to an existing CSS Injector rule that you apply site wide. What the CSS Injector module calls a “rule” would more appropriately be called a stylesheet; you can have many CSS rules in a single CSS Injector rule (stylesheet).
