You don't need headers like this, you should check corresponding DOM methods 
before using those methods and this would do the trick,

It's quite common(recommended) to use Document.getElementById to check DOM 
support in browser 9see attached example).
If you want to create some eleemnts dynamicaly - check createElement first, to 
be sure that it's supported.

For example, Document.getElementById  returns True in Opera6, but 
createElement method is not supported.

As about CSS - there is a well-defined fallback mechanism in CSS itself, I 
doubt you need any special methods to check it.
