Every theme has several elements that fit into the following structure:
Header
The header sits at the very top of the site. The purpose of the header is to match your brand and show global navigation that is above your community navigation. For a lot of sites a header isn't necessary, but the capability is there if you choose.
In the header, you can put whatever HTML/CSS you want.
Title Bar
The title bar is right below the header. It provides a place for Vanilla's navigation and common application components.
Some sites might have just a title bar rather than a header and a title bar. We provide options to add some branding and navigation into the title bar.
Banner
The banner area shows up on your home page only when users first visit your site. It has a big search bar and a place to upload a large image to really showcase your brand.
Main Content
The main content area is where most of Vanilla's functionality is. The main content changes depending on what page you are on. You customize the main content through a variety of variables.
Footer
The footer is at the bottom of your page and belongs to you. Smaller sites might have just a copyright notice, while large sites usually have columns of links to important documentation and social media.
Like the header, you can put whatever HTML/CSS you want in the footer.
