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-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: Granular roles keep sensitive work private while everyone else stays informed.

<span class="badge text-bg-primary text-wrap text-start">text-wrap badge: Granular roles keep sensitive work private while everyone else stays informed.</span>
</div>4Truncate
text-truncate cuts a single line with an ellipsis; it needs a block or inline-block with a width.
