search in google for it , its rounded border not working in IE8 , well rounded border nothing to do with html. Its all about CSS. You can get rounded borders by using images for all browsers ..
As has been said, you need to use the border-radius property in CSS3. Forget using images; you shouldn't be supporting old browsers.
Put this code within you <style> section: .rounded-corners { -moz-border-radius: 4px; -webkit-border-radius: 4px; -khtml-border-radius: 4px; border-radius: 4px; behavior: url(/css/border-radius.htc); } Also, you need to download www.gingle.co.cc/css/border-radius.htc If the border-radius.htc file opens up in your browser, just view the source and copy it to make another file by the same name (that is, border-radius.htc) Now, put this file in a /css/ folder relative to everypage where you want rounded corners. Now, whichever table or textbox or anything that you want to have rounded corners, just use rounded-corners as a class. eg. <table class="rounded-corners" > This also works on IE8 or IE7. The border-radius.htc file makes it possible for IE too. If you dont include the border-radius.htc file, the rounded corners wont appear on IE.
