-# Custom CSS
-Sometimes you want to add additional CSS for a feed to improve the rendering. This can very easily be done by adding a CSS class to **css/custom.css** following the following naming convention:
-
-* Take the URL from the \<link> attribute (e.g.: \<link>https://www.google.de/path?my=query \</link>)
-* Extract the Domain from the URL (e.g.: www.google.de)
-* Strip the leading **www.** (e.g.: google.de)
-* Replace all . with - (e.g.: google-de)
-* Prepend **custom-** (e.g.: custom-google-de)
-
-Each class rule should be prefixed with **#app-content** and should only affect the article body. An example rule would be:
-
-```css
-#app-content .custom-google-de .body {
-    /* Custom CSS rules here */
-}
-```
