How to style a checkbox without using any CSS framework.


Let’s get to the point. Here is what a normal checkbox looks like:

(Default Checkbox)

How do we go about styling a normal checkbox?

HTML input-type checkboxes cannot be customized with any properties, so we have to get creative with how we customize the input element.

What? How?

Step 1: Hide the input element.

Step 2: Add an extra span element and apply your custom style by creating a class.

#1 — Hiding the Input

There are three ways to hide an HTML element.

  • Display: None
  • Visibility: Hidden
  • Opacity: 0

If we set display:none, then any event listeners (like click listeners) on that element will not work. We need functioning event listeners because the checkbox has to toggle its state from checked to unchecked when a user clicks on it.

Similarly, the problem with  visibility:hidden is that some of the events won’t work with this property set.

If we set opacity:0, the element will be invisible but all the event listeners will still work; therefore, this is the property we will use to achieve our customization.



With opacity:0 in place, you can expect your checkbox to look like this:

#2 — Adding a Span Element

Why do we need a span element? Since we’re hiding the input checkbox and showing a custom-styled element that appears and behaves like a checkbox in its place, we use span as the placeholder element.  We use span  over block elements like div because it is an inline element that doesn’t take up the entire width.

Here is what our updated HTML would look like:

Let’s style the custom checkbox for unchecked state:


And again for checked state:


Now we can see our work in action:


One last thing!

Let’s incorporate some fun by adding transition animation when the state changes from unchecked to checked and vice versa.
