Rendering Engines

[Mk.32]

Any good website should work across all the major browsers.
Including FF, Chrome, Opera, and even IE 6 (usually the one that causes problems). See graphic below.

[Q. Sheets]

Actually, I'd stop worrying much about IE 6. Team 245, the team that won the Championship Website Award at the this past season, stopped supporting IE 6 a couple years ago. So here's my list of bare minimums:

Gecko:
- Firefox 3.6.23 (fallback browser*)
- Firefox 4+

Presto:
- Opera 10 (fallback browser*)
- Opera 11.11+

Trident:
- Internet Explorer 7/8 (fallback browser*)
- Internet Explorer 9

Webkit:
- Google Chrome 12+
- Safari 4+

Mobile browsers are strictly optional (in my humble opinion) for testing at this point. I'd leave them out of any testing until after you're satisfied with how the site looks on the desktop browsers.

* Fallback browsers support none or very few of the HTML5/CSS3 standards

Also, please do not turn this into a thread about IE 6 because there are a few threads in this forum on that topic already. If anything, just make sure the copy is readable in all browsers, even if the design isn't there.
