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.
<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>
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

<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>
Use the text-[<value>] syntax to set the font size based on a completely custom value:
<p class="text-[14px] ..."> Lorem ipsum dolor sit amet...</p>
For CSS variables, you can also use the text-(length:<custom-property>) syntax:
<p class="text-(length:--my-text-size) ..."> Lorem ipsum dolor sit amet...</p>
This is just a shorthand for text-[length:var(<custom-property>)] that adds the var() function for you automatically.
Prefix a font-size utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<p class="text-sm md:text-base ..."> Lorem ipsum dolor sit amet...</p>
Learn more about using variants in the variants documentation .
Use the --text-* theme variables to customize the font size utilities in your project:
@theme { --text-tiny: 0.625rem; }
Now the text-tiny utility can be used in your markup:
<div class="text-tiny"> <!-- ... --></div>
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; --text-tiny--letter-spacing: 0.125rem; --text-tiny--font-weight: 500; }
