space in classname uses classname .infobox

As ppk reported spaces in classnames will have buggy effects in Explorer Mac. It will use a class called .infobox for every element with an empty class name! Seems like it is an internal class for something.

I don't think that ".infobox" has anything special. A 'blank' class name matches every other name, not only infobox. I'm not exactly sure, but from some tests I did (, I believe that:
1) with a blank in front (class=" a" or class=" "), all other names are matched,
2) with a blank at the end, or in the middle (as in the case of multiple classes) the blank is attached to the previous string and all names starting with that string are matched (with class="a b" all name starting with 'a' are matched.)

In short: the blank acts as a sort of wildcard character.
