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.
Ninety cents of every dollar goes directly to the projects you support.
<p class="text-center text-sm-start text-lg-end border rounded-3 p-2 mb-0">Ninety cents of every dollar goes directly to the projects you support.</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: Ninety cents of every dollar goes directly to the projects you support.
</div>
<span class="badge text-bg-primary text-wrap text-start">text-wrap badge: Ninety cents of every dollar goes directly to the projects you support.</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">

</div>5Break long words
text-break wraps very long strings that have no spaces.
