Basic example

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

<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:

<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

Use the text-[] syntax to set the font size based on a completely custom value:

<p class="text-[14px] ...">
  <!-- ... -->
</p>
