Let's walk through how to create custom radio buttons with *pure CSS*, while still preserving performance and accessibility. + +## The Final Product + +This is what we will be designing: + + + +[Live CodePen Example](https://codepen.io/bradleytaunt/pen/oNjwMyX) + +- - - + +## The bones of our radio inputs (HTML) + + + <input class="radio-btn" name="radio-collection" id="radio-1" type="radio"> + <label class="radio-label" for="radio-1"><span>I am very satisfied</span></label> + + <input class="radio-btn" name="radio-collection" id="radio-2" type="radio"> + <label class="radio-label" for="radio-2"><span>I am satisfied</span></label> + + <input class="radio-btn" name="radio-collection" id="radio-3" type="radio"> + <label class="radio-label" for="radio-3"><span>I am indifferent</span></label> + + <input class="radio-btn" name="radio-collection" id="radio-4" type="radio"> + <label class="radio-label" for="radio-4"><span>I am unsatisfied</span></label> + + <input class="radio-btn" name="radio-collection" id="radio-5" type="radio"> + <label class="radio-label" for="radio-5"><span>I am very unsatisfied</span></label> + + +I know it looks like a lot is going on here, but it's pretty straightforward so let's unpackage line by line: + +### Radio inputs + + + <input class="radio-btn" name="radio-collection" id="radio-1" type="radio"> + + +This is the default `radio` input. We give it: + +- a `name` (inputs with a shared `name` are grouped together) +- an `id` (so our label can target this input) +- a `class` (so we can style it later) + +**Important**: be sure to have a unique `id` for each input so your labels don't end up connected to multiple radios. In this demo we are simply incrementing them by one. + +### Labels + +Adding the labels is fairly straightforward, we just include the corresponding input's `id` in the label's `for` attribute. The label content is wrapped in a `span` - which I will explain the reasoning for later. + +For styling purposes we also add the `radio-label` class. + + + <label class="radio-label" for="radio-1"><span>I am very satisfied</span></label> + + +This is looking pretty terrible - but that's nothing some good ol' CSS can't fix! + +## The flesh of our radio inputs (CSS) + +First we give some basic styling to our `label` and `input` classes (along with hover states). The `radio` element is actually hidden from view, but by using the `visibility` attribute we still keep it accessible for screen-readers. + + + .radio-label { + background: white; + border: 1px solid #eee; + border-radius: 5px; + box-shadow: 0 2px 4px rgba(0,0,0,0.05); + cursor: pointer; + display: inline-block; + font-weight: 600; + margin: 0 auto 10px; + /* This 65px padding makes room for the custom input */ + padding: 20px 20px 20px 65px; + position: relative; + transition: .3s ease all; + width: 100%; + } + .radio-label:hover { + box-shadow: 0 4px 8px rgba(0,0,0,0.05); + } + .radio-btn { + position: absolute; + visibility: hidden; + } + + +Remember that `span` element inside the label? We set it's `user-select` property to `none` so we avoid any possible issue with the user selecting the text on-click: + + + .radio-label span { + -webkit-user-select: none; + -moz-user-select: none; + user-select: none; + } + + +Next we include the default empty selection element (to mimic the original radio input) via a pseudo element: + + + .radio-label:before { + background: #eee; + border-radius: 50%; + content:''; + height: 30px; + left: 20px; + position: absolute; + /* Half the height of it's parent minus half of it's own height */ + top: calc(50% - 15px); + transition: .3s ease background-color; + width: 30px; + } + + +## A Few Final Steps + +The final step is adding the custom styling for when an `input` item is selected (`:checked`). + +You will notice the use of a `base64` element for the custom checkmark - feel free to subsitute this for an actual image or none at all (this is just my personal design preference). + + + .radio-btn:checked + .radio-label { + background: #ECF5FF; + border-color: #4A90E2; + } + .radio-btn:checked + .radio-label:before { + background-color: #4A90E2; + background-image: url('data:image/svg+xml;base64,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');
