I have a JQUI slider here, sized with percentages. I can use the border radius to round the slider, but the range highlight doesn't inherit this rounding:
If I update the class ".ui-widget-head" like this:
.ui-widget-header {
border-radius: 90px;
}
We get somewhere: http://jsfiddle.net/BjeNx/21/
But then, as the slider handle approaches the minimum value, the rounding gradually disappears!
This suggests it can be done!
