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-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>

text-nowrap keeps text on one line, text-wrap allows wrapping (for example inside a badge).

text-nowrap: This flexible launch brings customers coming back from the very first day.

</div>4Truncate
text-truncate cuts a single line with an ellipsis; it needs a block or inline-block with a width.
