If you build two page using page builder then you can deceide which elements you want to top or bottom. Besides, if you create an article then the design will be look like second screenshot. But, If you want Joomla defult design, Please let me know and share your administrator access. I will replace the main file of Helix. Thanks
So if I want to create 2 pages from scratch with each of those header layouts, what would be the steps for the top one and waht would be the different steps for the bottom?
