twitter bootstrap images grid - css

Question

I am using twitter bootstrap and I would like to create a grid that will shrink according to the width of the screen and move it cells down. Right now I managed to create a grid like this: http://jsfiddle.net/D2RLR/3179/.
The problem is that the grid is not aligned very well and if I shrink the window the images are getting smaller instead of moving to the next row.
Is there any well knows practice to do that?

<input id="search-term" type="text" placeholder="Type search term">

Answer 1

Change the container-fluid and row-fluid classes to container and row. Then include the bootstrap-responsive.css file. Work from there. Fluid and responsive is not the same thing, although they're related and often used together. Fluid layouts adjust their widths when resized, which seems to be not what you want. Responsive layouts generally adjust their layout when resized.

You will still probably want to mess with the layout a bit, but the functionality is there.
