Managing text in a fixed container

Hi, I have this field in my database with a datatype of text. Unfortunately, I can able to manage on how to display the text properly because the text is very long. Meaning to say, the text will be displayed in a single line and it will overlap the other section of my web page. Can anyone give me and idea on how am I going to address this issue.

@EricWatson: Thanks for giving me a link. It really help a lot. Thanks again.

If everything is displayed as a single line it mostly means the browser can’t find a place to wrap words, which usually occurs with either extremely long words, or all if all spaces in the text are represented by  
Can you check your text for the occurrence of either of those?
