I want to determine if a browser is compatible to the CSS framework Bootstrap. I want to show a note, if the given browser doesn't support it (e.g. Internet Exporer 8). I prefer the feature based detection with Modernizr, but I don't know which aspects/features I have to test to guarantee the compatibility to Bootstrap.
I don't want to get Bootstrap running with IE8, I just want to test if the given browser supports all features that are necessary to run with Bootstrap 3. So IE8 issue with Twitter Bootstrap 3 will not help me.
Does anyone have an idea which features I have to test with Modernizr?
