Let's create a custom toggle switch using HTML and CSS.

#css #webdev #beginners #tutorial

Hello everyone! In this quick tutorial, let's learn how to create a custom toggle switch using HTML and CSS.

Step 1 - The HTML.

<label class="switch">
     <input type="checkbox" class="checkbox">
     <span class="toggle-thumb">

          <svg xmlns="http://www.w3.org/2000/svg" width="36" height="36" viewBox="0 0 24 24" style="fill:#4ADE80;transform:;-ms-filter:"><path d="M10 15.586L6.707 12.293 5.293 13.707 10 18.414 19.707 8.707 18.293 7.293z"></path></svg>

          <svg xmlns="http://www.w3.org/2000/svg" width="36" height="36" viewBox="0 0 24 24" style="fill:#F87171;transform:;-ms-filter:"><path d="M16.192 6.344L11.949 10.586 7.707 6.344 6.293 7.758 10.535 12 6.293 16.242 7.707 17.656 11.949 13.414 16.192 17.656 17.606 16.242 13.364 12 17.606 7.758z"></path></svg>

     </span>
</label>

Here, the label with the class 'switch' is like the main container of our switch. The span with the class of 'toggle-thumb' is the circle part of the switch and inside this span are the 2 SVG icons that we are going to use. And We will use the checkbox to toggle the switch.

Step 2 - Basic Styles

.switch {
      display: inline-block;
      width: 60px;
      height: 34px;
      position: relative;
    }

.toggle-thumb {
      position: absolute;
      top: 0;
      left: 0;
      right: 0;
      bottom: 0;
      display: flex;
      justify-content: space-between;
      align-items: center;
      background-color: #475569;
      border-radius: 40px;
      cursor: pointer;
    }

After these styles, the switch should look like this

Step 3 - Creating the toggle thumb and hiding the checkbox.

For creating the toggle thumb we need to add the '::before' pseudo-element to the 'toggle-thumb'.

 .toggle-thumb:before {
      content: "";
      height: 26px;
      width: 26px;
      position: absolute;
      left: 4px;
      bottom: 4px;
      border-radius: 50%;
      background-color: #E2E8F0;
      transition: .4s all ease;
    }

And to hide the checkbox

.checkbox {
      opacity: 0;
      width: 0;
      height: 0;
    }

It should look like this now,

Step 4 - Adding the functionality.

To add the functionality to our switch we need to add transform to our 'toggle-thumb::before' when our checkbox is checked. So to do that,

.checkbox:checked + .toggle-thumb:before {
      transform: translateX(26px);
    }

That's it. Here is the demo of the switch.

Thanks 😀

Great tip!
I just did a small change to the CSS to give a transition effect to both the tick and the cross.

.toggle-thumb {
 ...
 overflow: hidden;
}
svg:nth-child(1) {
  position: relative;
  left: -26px;    
}
svg {
  transition: .4s all ease;
}
.checkbox:checked + .toggle-thumb > svg {
  transform: translateX(26px);
}

Hey! This looks amazing😍🤩 Thank u so much!

Nice quick tut! Since it's aimed to beginners, it would also benefit from a quick explanation of why clicking the also influences the invisible checkbox.

Gaurav • Mar 6 '21

Oh yea I actually forgot to add that 😅 Thanks for the suggestion

Francis Provost • Mar 10 '21

Really nice! I love that you used :checked instead of using some JS.

Don't forget to make it accessible to screen readers.
For that I would replace the label by a span. The input would be labelled somewhere else in the form. I would add aria-hidden on the span. That way screen readers will ignore the svgs that are not important for to understand the input.

Hey, thanks! I will surely make these changes.😄

Great article, i never tried to use css do that, alwayse use js to trigger an event, but css seems to be more accurate, thanks

I am wondering if you could suggest basic integration to, for example, switching themes? What would be the best approach?

Gaurav • Mar 12 '21 • Edited

Yes, we can use this toggle to switch themes using javascript. We will have to add an event listener on the checkbox to listen for the 'change' event and create a function that toggles the theme on the body. First, you have to define your dark-mode class in your CSS and the javascript will look something like this,

const checkBox = document.getElementsByClassName("checkbox");
const body = document.body;

checkbox.addEventListener("change", darkMode);

function darkMode() {
      body.classList.toggle("dark-mode")
}

Is there any reason not using .checkbox {display:none} instead of .checkbox {
opacity: 0;
width: 0;
height: 0;
}?

great material and presentation. thank you!

Hey, thank u so much for pointing that out. It's actually my fault😅 I was trying different things to hide that checkbox to see what works best (like display: none, height:0 width:0, opacity:0, etc), and by mistake, I forgot to remove the extra code when writing this article😅display: none also works!.
