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.

<p class="text-center text-sm-start text-lg-end border rounded-3 p-2 mb-0">Children are welcome, and our paediatric team knows how to make them smile.</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: Children are welcome, and our paediatric team knows how to make them smile.
</div>
<span class="badge text-bg-primary text-wrap text-start">text-wrap badge: Children are welcome, and our paediatric team knows how to make them smile.</span>
</div>4Truncate
text-truncate cuts a single line with an ellipsis; it needs a block or inline-block with a width.
