I am currently using the font size tag of "small" for our model railroad web site:
http://www.swwamodelrailroaders.com
and the font shows up in very different sizes in different browsers, IE, Chrome, Firefox, etc,
causing the loss of some of the information in some browsers.
What kind of font tag will give a consistent sized font so pages look the same size,
and the DIV boxes don't break?
Thanks for any suggestions:
