How to use calc() in Tailwind CSS?
The calc() function in CSS allows you to perform calculations for property values dynamically. While Tailwind CSS doesn’t directly support calc(), you can use it inline or with custom utilities.
1. Using Inline Styles
You can use calc() directly within the style attribute for dynamic property values.
<html>
<head>
<script src="https://cdn.tailwindcss.com"></script>
</head>
<body class="h-screen flex items-center justify-center
bg-gray-200">
<div style="width: calc(100% - 50px);" class="bg-blue-500
text-white p-5">
Width is 100% minus 50px
</div>
</body>
</html>
In this Example:
- Inline style is used to apply the calc() function to set a dynamic width.
- Tailwind classes like bg-blue-500 and p-5 are combined with the inline style.
2. Using Arbitrary Values
Tailwind CSS supports arbitrary values using square brackets, allowing you to integrate calc() directly into your classes.
<html>
<head>
<script src="https://cdn.tailwindcss.com"></script>
</head>
<body class="h-screen flex items-center justify-center
bg-gray-200">
<div class="w-[calc(100%-50px)] bg-green-500
text-white p-5">
Width is 100% minus 50px
</div>
</body>
</html>
- The w-[calc(100%-50px)] utility sets the width using the calc() function within Tailwind’s arbitrary value syntax.
- This method avoids inline styles, keeping the code clean and consistent with Tailwind’s utility-first approach.
