There are two avenues for modifying font size in Atlas.
The following classes can be used to accurately adopt a heading's size (h1- h6). These sizes are tied to the default heading sizes renderer within the markdown component.
Heading 1
Heading 2
Heading 3
Heading 4
Heading 5
Heading 6
<p class="font-size-h1">Heading 1</p>
<p class="font-size-h2">Heading 2</p>
<p class="font-size-h3">Heading 3</p>
<p class="font-size-h4">Heading 4</p>
<p class="font-size-h5">Heading 5</p>
<p class="font-size-h6">Heading 6</p>The following classes targets text that are not headings.
Extra large text
Large text
Medium text
Small text
Extra small text
<p class="font-size-xl">Extra large text</p>
<p class="font-size-lg">Large text</p>
<p class="font-size-md">Medium text</p>
<p class="font-size-sm">Small text</p>
<p class="font-size-xs">Extra small text</p>Appending -tablet to a font-size class will make that class applicable to tablet screen size and above. In this way, you may apply mobile-first font sizes, then apply a more fitting font-size for larger screens.
Heading level two on mobile, level one on tablet
Medium on mobile, large on tablet
<p class="font-size-h2 font-size-h1-tablet">Heading level two on mobile, level one on tablet</p>

Text is centered on tablet size and above.
<p class="text-align-center-tablet">Text is centered on tablet size and above.</p>The .text-wrap-pretty atomic can be used to prevent orphans, or situations where a line breaks and just one small word ends up on the next line. When the .text-wrap-pretty atomic is applied, the browser will instead try to cut the line so the break looks a little more balanced.
If your browser supports pretty text-wrapping, resize your browser window and notice the differences between how these two paragraphs break.

</p>.text-wrap-pretty has two caveats:
- Support: As of March 2024, support is mainly available in Chromium browsers. Browsers which don't support this rule will ignore it and break lines as usual. Treat this as a progressive enhancement.
- Performance: Calculating optimal line breaks can be expensive, especially for larger blocks of text. Use, but use sparingly.
