I compiled this jsFiddle demo so that you can see what i am going throw. Using the Twitter Bootstrap 2 i thought everything was fine and simple things were taken care until i hit with this. I don't understand if the markup is not right or the library doesn't handle this but the text when long just overflows out of screen/container
Try this:
div {
word-break: break-all;
word-wrap: break-word;
}
