There is a purple frame on the button which is selected (When we clicked on it has purple outline) . Is there is any way to remove it?
I tried a lot of thing even with CSS but not working. What am I doing wrong?
.your-radio-group-class input[type="radio"]:checked {
outline: none; /* Remove the outline (purple frame) */ }
Thanks

You probably want to remove the
box-shadow:Right-click on the element in the web-browser and select "Inspect" and, if enabled, that should bring up the developer console and show you the CSS properties of the element. You should then be able to see if the element has a box-shadow style (or inherits it from somewhere) and can toggle it on and off to see quickly whether that style is generating the purple border you are seeing. You can also check whether you have the correct CSS selector for the element when you inspect it (as the formatting may be on the label for the radio button and not on the radio button).
