Neon Light Checkbox - CSS Only

Are you tired of boring old checkboxes that blend into the background of your website? Want to add some pizazz and personality to your forms? Look no further than the world of CSS-only checkboxes!

With just a bit of CSS magic, you can turn those plain checkboxes into sleek, stylish elements that will make your forms stand out. And the best part? No JavaScript required!

First things first, let's create the HTML for our checkbox. It can be as simple as a div or a label. Then, add a class or id so that you can target it with your CSS.

index.htmlhtml
<div class="cBox">  <input class="cBox__input" id="checkbox" type="checkbox" />  <label class="cBox__label" for="checkbox">    <span class="cBox__border cBox__border--top"></span>    <span class="cBox__border cBox__border--right"></span>    <span class="cBox__border cBox__border--left"></span>    <span class="cBox__border cBox__border--bottom"></span>    <span class="cBox__tick"></span>  </label></div>

Now, it's time to break out your CSS wizardry!

That's it! But checkboxes aren't the only game in town. You can also use CSS to create custom radio buttons and toggle switches. These elements can be used to create more interactive and engaging forms, and can be customized to match the overall design of your website.

The possibilities are endless with CSS-only checkboxes. Want to make your checkboxes look like cute little aliens? Go for it! Want to make them look like buttons on a retro video game controller? Why not! The only limit is your imagination (and CSS skills, of course).

So don't be afraid to get creative and have fun with your checkboxes. Your users will thank you for the added personality and pizzazz on your website. Happy styling!
