Border-radius not working on Opera

The border-radius CSS3 property is used to create round corners on elements. Basically you could use it on most elements.


On Opera it will work only if the element you apply it to has display:block, it won’t work on any inline elements.

<a href="#" class="mylink">Link</a>

Css definitions:

background: red;

Handling padding, margin, border position in CSS3 with boz-sizing

Firefox and other browsers (Opera, Safari, Chrome) will place the padding, margin and border outside of the box (div, table or other element) changing the width and height of the element. Internet Explorer will place them inside the box and the width/height of the element will remain the same. You can see how this will [...]

CSS3 cross-browser background gradient

Since CSS3’s gradient backgrounds are fairly new the functionality in all browsers is different.
Here is a sample of how you can achieve cross-browser functionality:

filter: "progid:DXImageTransform.Microsoft.gradient(startColorStr="rgba(255, 255, 255, 0.5)", EndColorStr="rgba(255, 255, 255, 0)")";

Cross-browser CSS code to disable selectable text

Maybe you created your own custom button from divs, or you just want to disable the ability to select text on an element (Usually is used for elements that act like buttons).

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-o-user-select: none;
user-select: none;

Use all these selectors on the element. This should work on all browsers.

UL, LI – HTML and Css lists, horizontal positioning
