Bootstrap is the most popular HTML/CSS framework, and there are many good reasons why lots of developers use it to make websites. There are also many developers who complain about “bootstrapy” look of websites built on it. This is understandable, but as someone said, your users don’t care that your site is “bootstrapy”.
I’ve built a few Bootstrap-based websites, and for me, “bootstapy” look is not that important. What’s really important, though, is that when using Bootstrap, I think in its terms and usually select components from the available set, even though they may be a completely wrong solution to the problem. When you don’t have this popup or that dropdown button available, you won’t slap them everywhere, and think of a better UI. Thus, to clear the clouded mind, it’s a good idea to try other frameworks from time to time. This time I’ll cover minimalistic CSS frameworks, which are good Bootstrap alternatives when you don’t want to use all the features provided by it.
