Round Corners
Two3Five uses Round Corners to style Extra Content areas 1,2,3,4.Round Corners on content boxes are great for allowing certain content areas to stand out. However, be warned, since the round corners are generated by using Mozilla CSS code extensions that some browsers, like Internet Explorer, do not handle or read properly and will not be able to display.
So you can choose whether you'd like the nice Round Corners "on" for users of Safari and Firefox to enjoy, or you can turn them "off' so that you site can appear uniform across all browsers.
Round Corners Off
This page has been set up with the Round Corners option turned off in the Styles palette in the Page Inspector.
This is how Internet Explorer users see the world.
Personally I think this is dull, so for all of you out there using IE8/7/6, why not switch to a proper browser?
Just a thought!
