I am looking for a grid framewor in CSS that can auto adjust heights so everything is aligned.

Currently I'm using Bootstrap v3 with a resize hack, that ensures that columns in a row tries to adjust to the same height. As you can imagine this becomes tricky when there are columns and rows inside columns giving me sort of a recursive height adjustment.

Instead of trying to fix it or write my own grid framework from scratch I would like to see if an already made solution could fit me.

Here's a preview from how it could look like:

Flexbox etc are fine as long as it works back to IE10. It doesn't have to use Bootstrap features and I don't need components.
