change button shape and color?

[Dave]

Given this type of button:

<$button set="$:/state/basicslider$c$" setTo="show">.</$button>

Is there any way to change the shape to have rounded corners (and thus be a circle using the "." above)

Also, how do I change the background color of the button from the default grey?

Thanks,

Dave

<$button class="mybutton" set="$:/state/basicslider$c$" setTo="show">.</$button>

<style>

.mybutton {

border-radius: 50%;

background-color:red;

}

</style>
