How to style a checkbox using CSS

Answer 1

With pure CSS, nothing fancy with :before and :after, no transforms, you can turn off the default appearance and then style it with an inline background image like the following example. This works in Chrome, Firefox, Safari, and now Edge (Chromium Edge).

INPUT[type=checkbox]:focus
{
    outline: 1px solid rgba(0, 0, 0, 0.2);
}

INPUT[type=checkbox]
{
    background-color: #DDD;
    border-radius: 2px;
    appearance: none;
    -webkit-appearance: none;
    -moz-appearance: none;
    width: 17px;
    height: 17px;
    cursor: pointer;
    position: relative;
    top: 5px;
}

INPUT[type=checkbox]:checked
{
    background-color: #409fd6;
    background: #409fd6 url("data:image/gif;base64,R0lGODlhCwAKAIABAP////3cnSH5BAEKAAEALAAAAAALAAoAAAIUjH+AC73WHIsw0UCjglraO20PNhYAOw==") 3px 3px no-repeat;
}
