Question: Hi,
I'm using this code for a CSS3 Border Radius, how can I adapt it so that I only get a border radius on top?

```
border-radius: 15px;
-moz-border-radius: 15px;
-webkit-border-radius: 15px;

```

Thank you.

Answer: 
Use: 

```
border-radius:15px 15px 0 0;
-moz-border-radius:15px 15px 0 0;
-webkit-border-radius:15px 15px 0 0;

```

The order is: top left, top right, bottom right and bottom left.
Use the side specific border radius rules.

Ex:

```
-moz-border-radius-topleft:15px;
-moz-border-radius-topright:15px;
-webkit-border-top-left-radius:15px;
-webkit-border-top-right-radius:15px;
border-top-left-radius:15px;
border-top-right-radius:15px;

```

Note that the most recent versions of both Chrome and Firefox support the border-radius rule without the prefix whis is needed only for older versions.
