I have drupal and bootstrap in my site. In firefox site works a great, but opera and chrome not showing site like it should. Problem: http://i.imgur.com/e2H8lhl.png In firefox, safari or IE there is not that problem. Overflowing or what that is? Firefox and it's working right: http://i.imgur.com/16uvwsh.png
Without code, or a link to the actual page, how are we supposed to guess what's wrong? It can be a million different things - bad markup, crappy CSS, javascript fuckups... anything can be wrong, and you're not providing any useful info except for the images, which doesn't tell us squat, apart from the content moving to the left, which suggests something wrong with the CSS or structure, but since we can't see the code... we can't help.
Well when I see "bootstrap" in the question I already know we are going to find a load of crap. I wager that the markup is not valid, and the CSS is the kind if bloat we have come to expect from bootcrap. So before you even post the link run the markup and CSS through the validators so you will know in advance how badly coded it is.
