Here is a method I use for rounded corners. I only have a solid color method as of now also this does not work in IE6

I dont really feel like explaining selectors so you might want to look that up if you dont understand.

This will expand by height and width and requires only one image.

*{ padding:0; margin:0;}
html  { background: #45473f; height: auto; }
body  { width: 80%; margin: 20px auto; font-size:10px; font-family: Arial, Helvetica, sans-serif; }
p     { font-size: 1.2em; line-height: 1.2em;}
p ~ p { margin: 1.2em 0 0 0; }

/* *** Round Corners  #ffc658  - (background-position: -28px 0;) + (width: 12px;) or (height: 12px;) = background width *** */
.round_container div { background: #ffc658 url(images/sprite-round_corner.png) no-repeat; overflow: hidden; min-height:12px; line-height: 12px; padding:0; }
div.round_corners    { background-position: 0 0; background-color: transparent; float: left; width: 12px; height:12px; padding:0; }
.round_corners + div { background-position: -28px 0; background-color: transparent; float:right; width: 12px; height:12px; padding:0; }
div.round_content    { padding: 0 12px; }
.round_content + div.round_corners { background-position: 0px -28px; }
.round_content ~ div { background-position: -28px -28px; }

Any new ideas to add to this will be appreciated.

Why care about IE6.

Just use the CSS border-radius property and they will simply degrade to square corners in browsers that don't support it.

I have to agree..using CSS3 for rounded corners is far easier and supported by GOOD browsers. IE users will just get square corners.. poor them

I'll try this piece of code. Looks like it's useful in our site.

Interesting technique, but I'm with these two:

The sooner the web design community stops supporting IE6 & 7, the sooner we can all move on. I now tell my clients their will function in IE, but they won't look great - I simply let things like rounded corners degrade into square ones, as Chris suggests.

Then, it is good to show them an alert message to upgrade or use Firefox/Chrome.

Also, check from which countries those visitors are. If those visitors are in your target market, then you can try developing an alternate version for them. Otherwise, it is as good as bot traffic.
