Well I’ve just created the section that you’ve wanted using our theme settings. Please check the section after slider that I’ve created on your site. https://lemicaglar.com.tr/
This is the proper way to do it. You need to check the options also in row settings.
And yes I would suggest you to create a child theme or use the child theme that we’ve provided you & make customization like doing css & other things in there so that you will not need to loose any changes in your site. Hopefully this will help you.
Still if you’re confused please feel free to let us know that how we can help you. It’s better to import the demo content & then change the things accordingly so that you know how our theme demo works or you can build your own using the theme settings.
Best Regards
