I want an appearance similar to this (This site is demo for UnaCMS, another opensource CMS).

https://online.me/courses-home

The page has a top menu, hero section, then submenu followed by Grid.

With views, I managed to create views and able to list posts as grid. I tried various themes from Drupal but so far cannot get a similar appearance. Now trying with Bootstrap.

I am not a professional web developer, so trying to see if this can be achieved using Click and configure..

Any help on how to achieve this easily would be great.
