Documentation and examples for common text utilities to control alignment, wrapping, weight, and more.

Font size

Quickly change the font-size of text.

<p class="fs-1">.fs-1 text.</p>
<p class="fs-2">.fs-2 text.</p>
<p class="fs-3">.fs-3 text.</p>
<p class="fs-4">.fs-4 text.</p>
<p class="fs-5">.fs-5 text.</p>
<p class="fs-6">.fs-6 text.</p>

Font weight and italics

Quickly change the weight (boldness) of text or italicize text.

<p class="font-normal">Text without font style.</p>
<p class="font-italic">Italic text.</p>
<p class="fw-thin">Thin weight text.</p>
<p class="fw-extra-light">Extra-light weight text.</p>
<p class="fw-light">Light weight text.</p>
<p class="fw-lighter">Lighter weight text (relative to the parent element).</p>
<p class="fw-normal">Normal weight text.</p>
<p class="fw-medium">Medium weight text.</p>
<p class="fw-semi-bold">Semi bold weight text.</p>
<p class="fw-bold">Bold weight text.</p>
<p class="fw-bolder">Bolder weight text (relative to the parent element).</p>
<p class="fw-extra-bold">Extra-bold weight text.</p>
<p class="fw-black">Black weight text.</p>

Line height

Change the line height with .lh-* utilities.

<p class="lh-tight"></p>
<p class="lh-snug"></p>
<p class="lh-relaxed"></p>
<p class="lh-loose"></p>

Text alignment

Easily realign text to components with text alignment classes. For left, right, and center alignment, responsive classes are available that use the same viewport width breakpoints as the grid system.

<p class="text-left">Left aligned text on all viewport sizes.</p>
<p class="text-right">Right aligned text on all viewport sizes.</p>
<p class="text-center">Center aligned text on all viewport sizes.</p>
<p class="text-sm-left">Left aligned text on viewports sized SM (small) or wider.</p>
<p class="text-md-left">Left aligned text on viewports sized MD (medium) or wider.</p>
<p class="text-lg-left">Left aligned text on viewports sized LG (large) or wider.</p>
<p class="text-xl-left">Left aligned text on viewports sized XL (extra-large) or wider.</p>

Note that we don’t provide utility classes for justified text. While, aesthetically, justified text might look more appealing, it does make word-spacing more random and therefore harder to read.

Text transform

Transform text in components with text capitalization classes.

<p class="text-lowercase">Lowercased text.</p>
<p class="text-uppercase">Uppercased text.</p>
<p class="text-capitalize">Capitalized text.</p>

Note how .text-capitalize only changes the first letter of each word, leaving the case of any other letters unaffected.

Text decoration

Decorate text in components with text decoration classes.

<a class="text-decoration-none" href="#">This link has its text decoration removed</a>
<p class="text-decoration-underline">This text has a line underneath it.</p>
<p class="text-decoration-line-through">This text has a line going through it.</p>

Word break

Prevent long strings of text from breaking your components’ layout by using .text-break to set word-wrap: break-word and word-break: break-word. We use word-wrap instead of the more common overflow-wrap for wider browser support, and add the deprecated word-break: break-word to avoid issues with flex containers.

<p class="text-break"></p>

Text wrapping and overflow

Wrap text with a .text-wrap class.

<p class="text-wrap">This text should wrap.</p>

Prevent text from wrapping with a .text-nowrap class.

<p class="text-nowrap">This text should overflow the parent.</p>
