Is it possible to create, for instance, a box model hack while using in-line CSS?
For example:
Yeah like everyone above, if you can avoid doing it inline do!! But if you really need to go inline then parser filters are probably your best bet, these are certain characters you can use on properties such as the underscore hack in ie6
print("code sample");
style="position:relative;padding:5px; _position:absolute; _padding:10px;"
ie6 will still get the underscored styles, everyone else will just ignore them!
There is also using !important instead of underscore.
have a play around and see what happens, but again like above, try and avoid like the plague :)
