Question

Here an example http://jsfiddle.net/kSuS7/2/

It’s possible to be done with CSS/jQuery if text in .content have a long word so the .content height set to 300px and if in short text just remove the height.

Answer 1

Via CSS you can use max-height instead of height. But I’m not sure that it will work in IE 6,7 & maybe in 8 too.

So alternative safe way is to use Jquery.

$(document).ready(function() {
    if($("#content p").html().length>573)
    {

        $("#content").height(300);
    }
});
