You probably want to use CSS3 PIE instead.

Based on DD_roundies, but totally rearchitected to be less confusing, more
maintainable, and more feature-filled, this library adds support for the CSS3
border-radius property in IE7 and 8, but without ANY configuration required.

Rules are read directly from your stylesheets, so unlike other libraries, you
*do not* need to redefine your border-radius styles within JavaScript. Just and you’ve got rounded rectangles!


* A svelte 4.9kB once minified + gzipped
* No dependencies on external libraries
* Functions even if you are using an evil library that modifies
  Object.prototype (you know who you are)
* Properly object-oriented; no C masquerading as JavaScript here
* 100% configuration-free border-radius support
* Supports dynamically updating backgrounds and borders, without using polling
* Supports :hover and :focus pseudo-elements (for versions of IE with native
  support for these pseudo-elements)
* Supports input and textarea elements, and even drop-downs in IE8
* Functions properly in IE7 and IE8 strict mode
* (Almost) readable code with (nearly) complete jsdoc documentation
* No memory leaks!


* Only pixel units are supported for padding, border-width, and border-radius.
  Anything else will be assumed to be pixel width, even if it isn’t.
  You’ve been warned.
* Dynamic updates are about as responsive as a rock star in a drug-induced coma
  in IE8; in IE7, more like a 90-year-old missing their hearing aids.
* Sometimes, elements aren’t properly redrawn when a change causes several
  different elements to be restyled simultaneously (like, say, switching tabs.
  What a bunch of crap.)
* hasLayout is required, so it might break your design when rounded elements
  (and their parents) are surprised with the gift of layout
* Mouse events like mouseover, mouseenter, mousemove will start behaving
  erattically when the mouse moves over a rounded element. More specifically,
  hovering over an area of a rounded element that does not contain a child
  element will result in the mouse basically falling through the layer into
  VML’s cold, dead arms. There is a workaround in the code to try to mitigate
  this issue but it does not work 100% of the time.
* Could it support more of CSS3 backgrounds and borders, like, perhaps,
  rgba backgrounds? HECK YES IT COULD, TOTALLY! …but it doesn’t right now.


1. Load the script. You should really use conditional comments and only load
   for your lovely IE visitors, but it will work even if you forget.

3. Have a beer. You did a great job!

2. var roundrect = RoundRect.create(element, dynamic);
3. roundrect.destroy(); // restores the original glint and shine of your html
   // one you decide that this web 2.0 thing kinda sucks and round rectangles
   // are lame and outdated.
   // (in theory.)
   // …
   // (it hasn’t really been tested yet.)
4. Have two beers. You did twice the work, you totally deserve that extra one!
