Custom CSS Restriction

If your plan allows custom CSS, you can paste your own CSS into the box on your site settings screen. Any CSS defined will override the default.

Below are some of the restriction we have put in place for security reason. Those are the CSS which you wont be able to use

backslashes
import declarations (@import)
unicode entities
javascript-type words like "cookie" or "window"
known security issues like "moz-binding", any variation of "javascript" or "script", "behavior", "expression"
comments directly within your text, like text-color: #f00/ this is red /. Comments on a line of their own are allowed.
comments with weird structures, like /*/ or /**/
