Examples

Basic example

Use utilities like tracking-tight and tracking-wide to set the letter spacing of an element:

tracking-tight

The quick brown fox jumps over the lazy dog.

tracking-normal

The quick brown fox jumps over the lazy dog.

tracking-wide

The quick brown fox jumps over the lazy dog.

<p class="tracking-tight ...">The quick brown fox ...</p>
<p class="tracking-normal ...">The quick brown fox ...</p>
<p class="tracking-wide ...">The quick brown fox ...</p>

Using negative values

Using negative values doesn't make a ton of sense with the named letter spacing scale Tailwind includes out of the box, but if you've customized your scale to use numbers it can be useful:

@theme {
  --tracking-1: 0em;
  --tracking-2: 0.025em;
  --tracking-3: 0.05em;
  --tracking-4: 0.1em;
}

To use a negative letter spacing value, prefix the class name with a dash to convert it to a negative value:

<p class="-tracking-2">The quick brown fox ...</p>

Using a custom value

Use the tracking-[<value>] syntax to set the letter spacing based on a completely custom value:

<p class="tracking-[.25em] ...">Lorem ipsum dolor sit amet...</p>

For CSS variables, you can also use the tracking-(<custom-property>) syntax:

<p class="tracking-(--my-tracking) ...">Lorem ipsum dolor sit amet...</p>

This is just a shorthand for tracking-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a letter-spacing utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<p class="tracking-tight md:tracking-wide ...">Lorem ipsum dolor sit amet...</p>

Learn more about using variants in the variants documentation.

Customizing your theme

Use the --tracking-* theme variables to customize the letter spacing utilities in your project:

@theme {
  --tracking-tightest: -0.075em;
}

Now the tracking-tightest utility can be used in your markup:

<p class="tracking-tightest">Lorem ipsum dolor sit amet...</p>
