This article goes over the Onetopic course format in greater detail.
The Onetopic format now allows instructors to change the font and tab colours, as well as set up sub-topics to group tabs together.

Customizing Tab Colours

1. Switch to Onetopic format from the course settings. The settings can be accessed as shown in this guide.
2. From your course main-page, click on Edit Mode near the top right corner:
   
   
3. Click on the  3 dots and then on Edit section for the section you would like to edit:
   
   
   
   
4. The settings can be seen below:
   

   
   

   • "Level": This setting allows you to place the current tab at a level below the previous tab. This allows for the creation of sub-sections, for example.
     
     
   • "Text of the first tab in sublevel": This setting allows you to specify the name of the first sub-section in a set of sections.
     
     
   • "Font color": This setting allows you to specify the colour of the text for a given tab. The colour can be specified by common colour keywords (eg. Red, Green, Blue), by the RGB code (eg. reg(0, 255, 0)), or with a hexadecimal code representing the colour (eg. #ff033d). You can find more hexadecimal colour codes here.
     
     
   • "Background colour": This setting allows you to specify the colour of the background for a given tab. The colour can be specified by common colour keywords (eg. Red, Green, Blue), by the RGB code (eg. reg(0, 255, 0)), or with a hexadecimal code representing the colour (eg. #ff033d). You can find more hexadecimal colour codes here.
     
     
   • "CSS properties": This setting allows you change some CSS properties for the text (eg. font-weight: bold;).
