IMO if this is a side project to learn web development, your best bet is to pick one of the nice looking examples given in this thread, and then don't use it, just imitate the style. Why? Because if you use a framework rather than learning CSS, you will just waste time learning that framework's quirks which will not transfer over to anything. Most of the desirable features of these frameworks can easily be replicated with flexboxes anyway. Your own effort may not come out quite as smooth looking but you will learn a lot more along the way. I say this not as a CSS expert, but a guy in a similar situation who wasted a lot of time fiddling around with Bootstrap only to end up ditching it almost 100% in favor of custom CSS.
