Examples#

Basic example#

Use utilities like text-sm and text-lg to set the font size of an element:

{

text-sm

The quick brown fox jumps over the lazy dog.

text-base

The quick brown fox jumps over the lazy dog.

text-lg

The quick brown fox jumps over the lazy dog.

text-xl

The quick brown fox jumps over the lazy dog.

text-2xl

The quick brown fox jumps over the lazy dog.

}

<!-- [!code classes:text-sm,text-base,text-lg,text-xl,text-2xl] -->
<p class="text-sm ...">The quick brown fox ...</p>
<p class="text-base ...">The quick brown fox ...</p>
<p class="text-lg ...">The quick brown fox ...</p>
<p class="text-xl ...">The quick brown fox ...</p>
<p class="text-2xl ...">The quick brown fox ...</p>

Setting the line-height#

Use utilities like text-sm/6 and text-lg/7 to set the font size and line-height of an element at the same time:

{

text-sm/6

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

text-sm/7

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

text-sm/8

So I started to walk into the water. I won't lie to you boys, I was terrified. But I pressed on, and as I made my way past the breakers a strange calm came over me. I don't know if it was divine intervention or the kinship of all living things but I tell you Jerry at that moment, I was a marine biologist.

}

<!-- [!code classes:text-sm/6,text-sm/7,text-sm/8] -->
<p class="text-sm/6 ...">So I started to walk into the water...</p>
<p class="text-sm/7 ...">So I started to walk into the water...</p>
<p class="text-sm/8 ...">So I started to walk into the water...</p>

Using a custom value#

Responsive design#

Customizing your theme#

You can also provide default line-height, letter-spacing, and font-weight values for a font size:

@theme {
  --text-tiny: 0.625rem;
  --text-tiny--line-height: 1.5rem; /* [!code highlight] */
  --text-tiny--letter-spacing: 0.125rem; /* [!code highlight] */
  --text-tiny--font-weight: 500; /* [!code highlight] */
}
