IE style rule gotcha
I've been busy with massive project at the day job (launching soon, hope to mention it in detail here), and soon I'll be preoccupied with a C++ course, so I don't expect to be posting with any regular frequency here for the remainder of the summer.
I will share this, though: just because you can set style properties with a string:
elm.style.fontSize = "12px";
...doesn't mean IE will accept any old string:
elm.style.fontSize = "12px !important"; /* causes 'invalid argument' error in IE */
Firefox has no problem with this. Of course.
