How to add custom CSS
Sometimes the options provided by the Designer is simply not enough. In that case we have the Advanced section that lets you add any CSS you want.
Make sure you are
logged in, and then go to
Content > Design. Now select the
Advanced section in the menu at the top, which is highlighted in the image below.
Use the textarea to do a quick edit, or open the editor window using the button at the bottom. Any change to either of the windows is immedately applied. Notice that the Designer is locked until you close the editor window if you opened it using the button at the bottom.
