Hi Hoppy,

A while ago when IE7 was still a browser we needed to support mainly for corporate clients (and a browser I still have to build for at work), it caused a list of list one of which is the somewhat known hasLayout bug that plagued our good code and turned it into an horrible mess in the screen.

One hack a smarter developer came up with was to use zoom which magically redraws the element while containing floats that otherwise broke out layouts.

Now days unless you're supporting IE7 you need not worry about this as the modern day clearfix works without issue in IE8+.

Hope that helps.
