In the top toolbar, choose the brush icon.
Then, choose the aspect of your website that you want to change.
If you have a Pro site, you can even adjust the colors or shape details.
Note:
Tabs on a SimDif site are always located on the left-hand side. There is always one tab for each page. (One topic for each page)
