The black footer found at the bottom of your site cannot be edited and must stay consistent throughout all of the University websites.
However, if you wish, you can get an internal, fully customised footer, located just above the black one.
There are 4 sections in the internal footer and the content can be placed in a corresponding block: Footer 1, Footer 2, Footer 3 or Footer 4.
If you want to edit an existing text in the footer, hover over Structure and click on Blocks.
Scroll down to the Footer section. Click Configure to be able to make changes to the content.
Make edits in the Block Body area and save.
