Responsive CSS Grid layout-CodePudding

I'm making a page where there are three main sections, marked as Section 1, Section 2 and Main section. The main section contains some cards marked as card. Here's an example of the layout I want.

I also want it to be responsive, when resized the Section 2 falls at the bottom. Here's an example of what I want it to look like when resized.

This is basically all I need. I'm not good with CSS grid, but I assume this is done with columns and rows. I also assume that the cards area needs to be a grid or a flex to be responsive too.

Hope this makes sense and thx to anyone that helps in advance.

Try this

In w3 all explain how you build responsive website or page

Edit: score code is very long

Mostly you use flexbox for development [1]: https://www.w3schools.com/css/css_rwd_intro.asp
