Float unordered lists (UL) next to one another, and stack them at the bottom of each other, with no margins or spaces
问题 I have multiple unordered lists (UL) elements. Please check the image below: what I want to do is float the ULs next to each other. The ULs have different lenghts of content (LIs), therefore some UL are longer than other. When I float ULs next to each other in a limited width div layer, at some point the last ULs float at the bottom / left. However... if there's a UL that is longer there will be some space. I wish the ULs to float left and to stack to each other, at the bottom of each UL
