The New change the look options now have a lot of options to help us change how our site looks like, this includes:
Navigation (this I cover in a post only about the new Mega Menu)
The header options gives us 2 different layouts, Standard and Compact, ability to choose the Site Logo, and also we can apply a background color for the header element.
Footer Did someone tell they need a footer on a Intranet, now you can have that to, giving your users more navigation options, making it easier for them to navigation in your Intranet or SharePoint Sites. What elements can you add to a footer you might ask? Text, Image and Hyperlinks.
