问题 Based on an existing answer, I have managed to centre crop an image. I am having trouble making the centre cropped image responsive, though.

The problem is perhaps demonstrated more clearly with a Fiddle. How can I make the centre cropped image scale down nicely? Ideally the centre cropped image will

问题 I am trying to understand Bootstrap 3 's responsiveness. I understand in css if you have 2 classes on an element, then the 2nd class will override the first class. But, when you create a responsive design with Bootstrap , your element will look something like this: <div class="col-sm-1 col-md-6 col-lg-11"></div> Is it the css that switches between these classes depending on the size of the screen?

问题 I am trying to figure out Joni Korpi's Frameless CSS frameless grid (http://framelessgrid.com/) and I'm having a hard time reading the .less file he has. I have a basic understanding that LESS uses variables so I know column = 48 and gutter = 24 and that's about it. Does 1cols = 1 * (48 + 24) - 24)/ 12 ? What I don't understand is @1col: @1cols; and .width (@cols:1) { width: (@cols * (@column + @gutter) - @gutter) / @em; } Can anybody help? https://github.com/jonikorpi/Frameless/blob/master
