Does cesium's label support rounded backgrounds

I want to add some rounded corners to the label’s background, is this possible?

HI @Yi-Long,

I don’t think that is possible “out of the box”. If you must have rounded corners, you should build the label with a html element on specific position. Look at these Stackoverflow- and Sandcastle-Links:

Now you can style the labels with CSS.
Thanks to @emackey for his help there!

Thanks, this is also a very nice way, I can only use it
