Problem

One of the most common pain points in web development is styling checkboxes and radio buttons. They are notoriously difficult to style consistently across browsers and platforms. However, with a little CSS magic, you can create custom checkboxes and radio buttons that look great and are easy to use.

For a custom checkbox, the best solution I've found is to use an <svg> element to create the checkmark symbol and insert it via the <use> element to create a reusable SVG icon.
You can then create a container and use flexbox to create the appropriate layout for the checkboxes. Hide the <input> element and use the <label> associated with it to display a checkbox and the provided text.
Then, using stroke-dashoffset, you can animate the check symbol on state change. Finally, use transform: scale(0.9) via a CSS animation to create a zoom animation effect.

Solution

<svg class="checkbox-symbol">
  <symbol id="check" viewbox="0 0 12 10">
    <polyline
      points="1.5 6 4.5 9 10.5 1"
      stroke-linecap="round"
      stroke-linejoin="round"
      stroke-width="2"
    ></polyline>
  </symbol>
</svg>

<div class="checkbox-container">
  <input class="checkbox-input" id="apples" type="checkbox" />
  <label class="checkbox" for="apples">
    <span>
      <svg width="12px" height="10px">
        <use xlink:href="#check"></use>
      </svg>
    </span>
    <span>Apples</span>
  </label>
  <input class="checkbox-input" id="oranges" type="checkbox" />
  <label class="checkbox" for="oranges">
    <span>
      <svg width="12px" height="10px">
        <use xlink:href="#check"></use>
      </svg>
    </span>
    <span>Oranges</span>
  </label>
</div>

For a custom checkbox, the best solution I've found is to use an <svg> element to create the checkmark symbol and insert it via the <use> element to create a reusable SVG icon.

For a custom radio button, you can use pseudo-elements to do the heavy lifting. Same as before, create a container and use flexbox to create the appropriate layout for the radio buttons. Reset the styles on the <input> element and use it to create the outline and background of the radio button.
Then, use the ::before pseudo-element to create the inner circle of the radio button. Use transform: scale(1) and a CSS transition to create an animation effect on state change.
