Rounded corners for <input type='text' /> using border-radius.htc for IE

Answer 1

That won't work in IE<9 though, however, you can make IEs support that using:

CSS3Pie

PIE makes Internet Explorer 6-8 capable of rendering several of the most useful CSS3 decoration features.

Answer 2

Oh lord, don't do it this way. HTC files are never a good idea for performance and clarity reasons, and you're using too many vendor-specific parameters for something that can easily be done cross-browser all the way back to IE6.

Apply a background image to your input field with the rounded corners and make the field's background colour transparent with border:none applied instead.

Answer 3

Writing from phone, but curvycorners is really good, since it adds it's own borders only if browser doesn't support it by default. In other words, browsers which already support some CSS3 will use their own system to provide corners.
