Text
Text utilities handle alignment (with responsive variants), wrapping, truncation, breaking, transforms, font size, weight and style, line height, monospace and decoration. Combine them to build headings, meta lines and price tags without touching CSS.
1Text alignment
text-start, text-center and text-end.
text-start
text-center
text-end
<div class="d-grid gap-2 small">
<p class="text-start border rounded-3 p-2 mb-0">text-start</p>
<p class="text-center border rounded-3 p-2 mb-0">text-center</p>
<p class="text-end border rounded-3 p-2 mb-0">text-end</p>
</div>2Responsive alignment
text-center text-sm-start text-lg-end changes alignment per breakpoint.
Automations take care of the repetitive steps, so people can focus on real work.
<p class="text-center text-sm-start text-lg-end border rounded-3 p-2 mb-0">Automations take care of the repetitive steps, so people can focus on real work.</p>3Wrap and no wrap
text-nowrap keeps text on one line, text-wrap allows wrapping (for example inside a badge).
<div class="d-grid gap-2" style="max-width:14rem">
<div class="border rounded-3 p-2 text-nowrap overflow-hidden small">
text-nowrap: Automations take care of the repetitive steps, so people can focus on real work.
</div>
<span class="badge text-bg-primary text-wrap text-start">text-wrap badge: Automations take care of the repetitive steps, so people can focus on real work.</span>
</div>4Truncate
text-truncate cuts a single line with an ellipsis; it needs a block or inline-block with a width.
<div class="d-grid gap-2" style="max-width:18rem">
<div class="text-truncate border rounded-3 p-2">
Every update lands in one place, so nothing gets lost in email threads. Granular roles keep sensitive work private while everyone else stays informed.
</div>
<span class="d-inline-block text-truncate border rounded-3 p-2" style="max-width:150px">Your whole team, finally in sync</span>
</div>5Break long words
text-break wraps very long strings that have no spaces.
