Perhaps this isn't a mystery, because I don't have access to older browser windows, like Internet Explorer 9 or below.
But this does bring a rather interesting question to the table. While attempting to use programs like Browserstack and Sauce Labs, my Internet Explorer 8, 7 and 6 tests fail horribly, considering they aren't rendering the CSS3 elements with Modernizr installed (more particulary my one border-radius element).
My latest test was the following webpage: http://www.pixelandthewolf.com/test20.html
If you run this test in Internet Explorer 8, 7 or 6, with Browserstack or Sauce Labs, the section_one div won't have the border-radius element applied to it.
So this situation got me a bit curious and then I decided to test a working page with Modernizr installed correctly. This would be:
And what happens when you run this test in Browserstack and Sauce Labs with Internet Explorer 8, 7 and 6 being the choice? The same thing happens.
With all of this being said, perhaps there's some element I'm missing here and it's not just that Browserstack and Sauce Labs won't render the page correctly?
Any help is appreciated.
