This tutorial will show you how to implement coding that will allow your navigation menu to stick to the top of the page when someone scrolls beyond it.
Step 1. find your navigation's div id
Right click on your navigation and scroll down to and select "inspect element". A window will appear showing you the ID for your navigation menu's div.
This tutorial's navigation ID is "nav-wrap".
You're done! Publish your site to see your navigation stick to the top of the page when you scroll by it.
Tips & additional information
If you want your navigation menu to stick to the top after someone scrolls by it for just an individual page and not the entire site, you'll need to perform Step 2. a little differently.
