Don’t be a beta hater

Yes, Happy Cog has a layout problem in Internet Explorer 7 beta. Not to worry: According to Molly Holzschlag of The Web Standards Project, Microsoft has fixed the problem, as we’ll see in a future IE7 release. The current beta chokes on this rule:

div#headwrap h1	{
	background: transparent url(/i/happycog.gif) 
		top left no-repeat;
	margin: 0;
	border: 0;
	padding: 0;
	padding-top: 100px;
	overflow: hidden;
	height: 0px !important; /* for most browsers */
	height /**/:100px; /* for pre 6.0 IE Win */

It’s an image replacement technique that uses an alternate box model hack.

Designers use box model hacks to compensate for inaccuracies in the way some browsers (mostly Microsoft’s) calculate element widths with respect to padding and borders. I wrote this rule to insert my agency’s logo at the top of the page in visual browsers while presenting a text equivalent for screen readers and nongraphical browsers. The hacks force older Microsoft browsers to display these elements correctly.

When Microsoft released IE5, it was great for its day, but not always accurate. When they released IE6, it was better but not perfect. The company then declared victory and announced that the browser was dead and there would be no more IE browsers forever.

So designers got busy compensating for the standards deficiencies of IE5, IE5.5, and IE6 (and other companies’ browsers), using hacks like those seen here. The idea is to take the hackery out of markup, where it never belonged, and hide it in style sheets.

IE7 beta’s standards accuracy is already very good and getting better, and, despite what you might have heard to the contrary, Microsoft’s engineers are working with the community (and in particular with The Web Standards Project) to identify and fix CSS bugs and errors and to compensate for hacks like the one seen here. Using IE7? Finding bugs? Microsoft and The Web Standards Project want to hear from you.
