If I want to have a website with two column layout that works on both old browsers and mobile and modern browsers, is that achievable, without too much fuss?
If I just use float: left; for the navigation column will that just work, or...
I remember that using float was annoying, but I don't remember in what way
Ok, I remember now why I hate css float.
I think I'm going to design my website with one column (for mobile and old browsers). Then I'll use css supports query to detect if browser supports flexbox and then I use that for the two column layout for desktop.
