I implemented flex pattern in the header, with space in between, amongst them you can navigate to the About page, where you can access Details.
On the Home page it made sense to have the signup section be displayed as a grid. I like this idea becasue I can add more information on the grid.
Using the developer tools I was able to make sure that when the site is in a mobile view or collapsed, the information on the header stacks and the grid essentially becomes stack.
I have a Toggle and Details setup however, they aren't consistenly working.
