Had a bit of a problem getting the columns at equal size with flexbox, found this article and it turned out to be very helpful and i learned new things about when and why do we use flex: 1 or flex-basis: 100% and what's a better approach. Totally recomended. https://css-tricks.com/equal-columns-with-flexbox-its-more-complicated-than-you-might-think/ First time to to use BEM for HTML classes and it's really useful. Would appreciate any feedback.
