RE: Gabriel Martínez's "Four card feature section using CSS Grid, Media Quieries and variables" solution0Great site! I used CSS grid for the first time on this too. Where you have 3 columns with fixed pixels you could instead use 1fr (1 fraction). Repeating this three times would give each element a third of the screen.You can also use auto on the rows and it'll fit content. These options allow you to be more responsive over fixed widths.You can also define grid areas using grid-tempate-area which is worth looking into. I really like that feature. It's easier to write 'content' or 'hdr' etc. than column 2/5 and row 1/3 to define an area.I'm new to CSS Grid and CSS in general, but I found these useful. I hope they help you. I found this video useful: https://m.youtube.com/watch?v=7kVeCqQCxlk because he also has a codepen. He uses grid-template-area.Also, Google Scrimba CSS Grid.
