Is There a Setting to Auto-Adjust Font Size Based on Screen Resolution and/or Table Size?

I'm still trying to get a feel for developing for multiple platforms. I've been using a combination of bootstrap and html5 with asp.net web forms (c#), and so far it's working pretty well. One question I do have though, is there a setting or class that will automatically adjust font size based on either a user's screen resolution, or the size of the table that they are looking at? I've built a dynamic table that allows users to pick which fields they want to see, it has a base of 11 columns and can go all the way up to 23 columns. The resolution on my screen is tiny - 1680 x 1050, and I'm also sporting a 22" widescreen monitor, so everything fits on my screen up until about the 19th column gets added. For users with larger resolutions and/or smaller monitors, I imagine their tables are going to "fall off the side" before then. Currently when this happens, auto-scroll takes over and they can simply scroll over to see what's not on the screen, but with bootstrap ...
