Range Slider Color

[RyJo]

Hello,

Does anyone know how to change the color of just the First Half of this Range Slider Bar?

Here is the link to the example on W3: https://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_js_rangeslider_round

Thank you.

There's nothing that works in all browsers. There are a few non-standard selectors: Firefox has ::-moz-range-progress, Internet Explorer has ::-ms-fill-lower. There's no equivalent in other browsers.

If you want a slider that works well in all browsers you'll have to build it from scratch using Javascript.
