Tailwind CSS: Use a Checkbox to Show/Hide an Element
This concise and straightforward article shows you how to check/uncheck a checkbox to show/hide another element. We’ll only use Tailwind CSS to get things done. No Javascript is required.
What is the point?
Tailwind CSS offers a utility class and a modifier called peer and peer-* that can be used to style an element based on its sibling. In our case, we add the peer class to the checkbox and add peer-checked:visible to the element we want to show conditionally (this element is invisible when the checkbox is unchecked).
For more clarity, see the practical example below.
Example
This example mimics a real-world scenario where a user must agree to the terms of service of a website to continue doing something on that website.
Preview:
The code:
<body class="p-40 bg-sky-200">
<form class="space-y-5">
<h1 class="text-2xl text-gray-600 italic">KindaCode.com - Example</h1>
<div>
<input type="checkbox" name="agree" id="agree" class="peer" />
<label for="agree" class="ml-3">To continue, you must agree to
<a href="#" class="text-blue-500 underline">the Terms and
Conditions</a>
</label>
<div class="mt-10 invisible peer-checked:visible">
<button type="submit" class="w-96 px-5 py-2 bg-amber-400 hover:bg-amber-600 rounded-md">Continue</button>
</div>
</div>
</form>
</body>That’s it. Further reading:

That’s right. The peer class must be added to the element before.
