I have a daily article on my site with a preview/read more "ad" on the homepage. (Click Here (Being rebuilt)

Up to now I've been manually editing the 31 php daily files to insure the text fits within the window. I KNOW there is an easier way to do this because allowing for all of the different browsers and PC/Apple differences is a real pain!

I'd prefer not to have to use a database if I can get away with it.

Anyone have any ideas? I'd appreciate any help you can offer.
