I have added custom styles to radio buttons on my website to give them a custom style. My HTML and CSS code is attached in the above snippet. However, now when I click on an input it does not select. I would ideally like to have this working without a JS component.

One of the issue I find was, you have not specified the color after the radio button is clicked and also the sibling selector was missing. I have added these lines specifically:
.radio-container input:checked ~ .radio {
background-color: #2196F3;
}
Hope it helps!! Thanks.
