Four card using Grid

Hi!

Another complete project, I used CSS Grid, although my knowledge is still quite basic, I was happy to complete another project with GRID and be more comfortable using it.

I set the height of the cards using the px unit, is that correct?

I also used absolute position to position the side cards, but I'm not sure if this could be a problem because I'm using the css Grid.

Any comments will be appreciated. ;)
