Custom CSS

Target Audience: Administrators

Release version: 4.3.9


This section describes the functionality of Additional CSS, and how it is reflected in the Portal after being set. If you are interested in how Additional CSS is set, we recommend Admin > Custom CSS instead.

The standard for HTML-styling is CSS (Cascading Style Sheets), and is as such the only supported format for implementing your own stylesheet.

How are custom stylesheets used?

Once a custom stylesheet is set, and all the necessary checks have been made, it is directly linked as seen below:

<link href="CUSTOM-STYLESHEET-LINK.css" rel="Stylesheet" type="text/css" />

Based on HTML standards and our own principles, custom stylesheets are linked last and in the HEAD of the page. No validation is made to the syntax of the submitted CSS.
