How to apply this style in firefox? What is the problem that cause not showing in Firefox?

I have already tried the following solution:

Styling radio button - not work in IE and Firefox How to change style of radio and checkbox input

CodePudding user response：

I like Sato's answer, but you could also add this to your CSS:

input[type='radio'] {
  -moz-appearance: initial !important;
}

I'd try to avoid using !important in your CSS, it's not a good practice to use. I think if you remove it from your code, you could probably remove it from my snippet.

CodePudding user response：

I think this code will work for you.

.checkbox {
  position: relative;
  padding-left: 30px;
  margin-right: 20px;
}
.checkbox input {
  width: 0;
  height: 0;
  position: absolute;
}
.checkbox span {
    width: 20px;
    height: 20px;
    border-radius: 3px;
    position: absolute;
    left: 0;
    top: -1px;
    background-color: #fff;
    content: '';
    display: inline-block;
    visibility: visible;
    border: 2px solid #776330;
    box-sizing: border-box;
}
.checkbox span::after {
    position: absolute;
    content: '';
    left: 2px;
    top: 2px;
    width: 12px;
    height: 12px;
    background-color: #776330;
    display: none;
}

.checkbox input:checked ~ span::after {
    display: block;
}

<label class="checkbox" for="payment_method_stripe">
