Edit: Oh. I have just found out by another HN post that I did not understand the new grid system... Here is a link that explains it very well: http://www.helloerik.com/bootstrap-3-grid-introduction http://www.helloerik.com/bootstrap-3-grid-introduction I have used the release candidates for my own personal website and it has been a pretty good experience. However I liked the result I got with Bootstrap 2 more. To say it upfront: I am not a web developer. I am doing something completely different professionally. But maybe that makes my experience with Bootstrap kinda interesting… :) I had the main problem with the mobile first grid system. It changed quite a lot when compared to Bootstrap 2. I made a product page for my new app and I wanted to show thumbnails. When using the built in thumbnail class wierd things happen when you resize the window: The actual size of the thumbnail changes and it gets distorted as a result. Also the new grid system has the effect - at least in my case - that when resizing the window, the overall width of the columns that contain my text expand even though I made the window smaller. And then when I make the window even smaller the columns containing my text are becoming less wide. I think this is because of the fluid layout. Personally I do not like fluid websites at all. Maybe I should not have used bootstrap then but I had some experience with it… What I liked about the non fluid grid system in Bootstrap 2 was that your website looked more or less the same on desktop and on mobile. On mobile the first thing you would see is a scaled down version of your website with the structure in tact. If you wanted to see the details you would have to zoom in. Now Bootstrap tries to be smart and transforms columns to rows… This is obviously good if you want a fluid website. When I had to do it again I would not use bootstrap again. Instead I would look for something that has a grid system like boostrap 2.
