RTE HTMLarea

7.1.5. Safari and CSS class names

CSS class names are case sensitive. However, as of Safari 3.1 (525.13), the stylesheet API returns only lowercase text. Therefore, if css class names with uppercase letters are used, they may not appear in the block style and text style drop- down lists because the check against lists of allowed classes fails. If you intend to use the RTE in Safari, you should make sure to use only lowercase letters in your class names.
