HTML / CSS & Widgets
The editor has quite a bit of options built in for designing and editing a website. But there still may be some situations where you want to use Custom HTML. So we've written this short guide to show how to make a few basic changes / additions (you are welcome to make more changes if you know your way around HTML).
Due to all the possible variations involved, these kinds of changes are not something for which we are able to directly support, fix or provide guidance for -- so if the changes do not work properly with your theme or are not something you feel comfortable doing, the best thing you can do is stick with a standard theme via the Design tab.
