(HTML/CSS) Can i have fixed width columns with different number of columns per row? : So what i'm trying to do is have a grid with the following specs:
- In screens < 400px, show 1 column per row
- In screens > 400px and < 800px, show 2 columns per row
- In screens > 800px, show 4 columns per row
- In all screen sizes, each column should have a width of 25% of screen size

How would you do this?
