How to Utilize Dynamic Class Manipulation in Tailwind CSS with Template Literals?

In Tailwind CSS, conditional class assignment allows developers to dynamically update class names based on specific conditions. However, encountering issues when attempting to utilize this feature is not uncommon.

In one such instance, a user tried to change classes using the following code:

<div
  className=" absolute inset-0 ${click ? translate-x-0 : -translate-x-full }
        transform  z-400 h-screen w-1/4 bg-blue-300"
>
</div>

However, this code snippet failed to function as expected. The correct approach for this scenario is as follows:

<div className={`absolute inset-0 ${click ? 'translate-x-0' : '-translate-x-full'} transform z-400 h-screen w-1/4 bg-blue-300`}></div>

Alternatively, you can also use the following syntax:

<div className={'absolute inset-0 ' + (click ? 'translate-x-0' : '-translate-x-full') + ' transform z-400 h-screen w-1/4 bg-blue-300'}></div>

It's crucial to avoid using string concatenation for class creation, as demonstrated below:

<div className={`text-${error ? 'red' : 'green'}-600`}></div>

Instead, select complete class names:

<div className={`${error ? 'text-red-600' : 'text-green-600'}`}></div>

Tailwind will retain classes that appear in their entirety within your template during the production build.

In addition, there are further options at your disposal, such as:

• Using libraries like classnames or clsx
• Employing Tailwind-specific solutions like twin.macro, twind, or xwind
