Hi team,

I have been trying to override the default settings for radio buttons, but am really struggling with it?

What is the way to make changes?

Cheers,

There is no right way of styling radios. How are you trying to style them?

<style>
.radio-button{
  ...
}
</style

I thought that approach might work when overriding the default settings for firefox and chrome, but I doesn’t work.

Want to basically make the radio button larger and want to change the background and border radius.
