Why are browser-specific CSS hacks not patched by agent developers?

Second line of the following is not recognisable by IE6/Windows

#header {margin-bottom:3em}
html>body #header {margin-bottom:1em}

I can understand that the child selector is a feature not implemented by IE6. But IE/Mac will not recognize the following:

/* Hide from IE-Mac \*/
#header {margin-bottom:3em}
#footer {margin-top:1.5em}
/* End hide */

This seems to be a bug. Usually agent developers gives patches. Why it is not patched? Any specific reason?

Solution

  • Possible explanations:

    1. In order not to break the existing hacks on hundreds of sites around
    2. Too busy patching other hundreds bugs
