Detecting text outside of text boxes Options

[tooPrime]

I have a text box on a website that I need to fill with headlines from an RSS feed. I've gotten code that can take the information from an RSS, but my problem is the length of the headlines are quite volatile, so depending on the headlines the box will be extremely empty or the words will bleed outside of the box. There is a parameter in the function that reads the RSS feed that specifies how many headlines to display. Is there some way I can increase this number until the words spill out of the box and then go one less? My programing prowess is subpar so I'm not even sure how to search a tutorial to do this. If anyone can tell me how or reference a tutorial that would help I would be very happy.

You might compare values for height and scrollHeight, if the latter is larger it implies overflowing content (though I recall it's a bit random at times).
