I'm attempting to create a responsive display so that a page renders nicely in various screen resolutions. I have a design concept that has 4 equal width columns. However, I'm trying to figure out how to make the height of each column adjust to match as well. For example, in this layout - https://cairn.edu/custom/test2.php
- how can I make the height of columns 1, 2 and 3 follow the height of column 4 based on whatever content is in column 4?
I found another example that actually does what I want but it seems to use Bootstrap and I can't put my finger on the code that is actually making it work the way I want. That page is https://cairn.edu/custom/test5.php
