Page editing is complicated and difficult. Yes, we are wep developer but it should be basic for other clients. (It seems related to Visual Composer but I have to do it the simple way)
Theme’s main and most important builder is Codeless Builder. To access it just click on the “Page Customize” buttons (screenshot) you see in back-end. Then start customizing page’s options or each element on it’s own as showed in our documentation and Video Tutorials.
Once you get familiar with it, you will see the easy it is to customize each section of the site separately and independent from other elements of the page.
Let us know if you have any question.
