Often, I need to change the way I apply some CSS due to the different box models that browsers employ. Some include padding, some borders, some other stuff in their calculations of widths during their layout phase. I stumbled across this interesting way of detecting the browser that the visitor to your site has decided to use.
I put the version numbers on those
isXXX variables because those’re the
versions that I used to test those values. They might work for other versions,
If you use this trick and find a different value or even the same value, then please post your discovery on this page and we can compile a list of very easy-to-use tests for browser detection!
