Clearfix
Quickly and easily clear floated content within a container by adding a clearfix utility.
Easily clear floats by adding .clearfix to the parent element. Can also be used as a mixin.
Color and background
Set a background color with contrasting foreground color.
Colored links
Colored links with hover states
Focus ring
Utility classes that allows you to add and modify custom focus ring styles to elements and components.
Icon link
Quickly create stylized hyperlinks with Bootstrap Icons or other icons.
Position
Use these helpers for quickly configuring the position of an element.
Ratios
Use generated pseudo elements to make an element maintain the aspect ratio of your choosing. Perfect for responsively handling video or slideshow embeds based on the width of the parent.
Stacks
Shorthand helpers that build on top of our flexbox utilities to make component layout faster and easier than ever.
Stretched link
Make any HTML element or Bootstrap component clickable by “stretching” a nested link via CSS.
Add .stretched-link to a link to make its containing block clickable via a ::after pseudo element. In most cases, this means that an element with position: relative; that contains a link with the .stretched-link class is clickable. Please note given how CSS position works, .stretched-link cannot be mixed with most table elements.
Text truncation
Truncate long strings of text with an ellipsis.
For longer content, you can add a .text-truncate class to truncate the text with an ellipsis. Requires display: inline-block or display: block.
Vertical rule
Use the custom vertical rule helper to create vertical dividers like the <hr> element.
Visually hidden
Use these helpers to visually hide elements but keep them accessible to assistive technologies.
Visually hide an element while still allowing it to be exposed to assistive technologies (such as screen readers) with .visually-hidden. Use .visually-hidden-focusable to visually hide an element by default, but to display it when it’s focused (e.g. by a keyboard-only user). .visually-hidden-focusable can also be applied to a container–thanks to :focus-within, the container will be displayed when any child element of the container receives focus.
Breakpoints
Breakpoints are customizable widths that determine how your responsive layout behaves across device or viewport sizes in Bootstrap.
Columns
Learn how to modify columns with a handful of options for alignment, ordering, and offsetting thanks to our flexbox grid system. Plus, see how to use column classes to manage widths of non-grid elements.
Containers
Containers are a fundamental building block of Bootstrap that contain, pad, and align your content within a given device or viewport.
CSS Grid
Learn how to enable, use, and customize our alternate layout system built on CSS Grid with examples and code snippets.
Grid system
Use our powerful mobile-first flexbox grid to build layouts of all shapes and sizes thanks to a twelve column system, six default responsive tiers, Sass variables and mixins, and dozens of predefined classes.
Gutters
Gutters are the padding between your columns, used to responsively space and align content in the Bootstrap grid system.
Utilities for layout
For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
Z-index
While not a part of Bootstrap’s grid system, z-indexes play an important part in how our components overlay and interact with one another.
Several Bootstrap components utilize z-index, the CSS property that helps control layout by providing a third axis to arrange content. We utilize a default z-index scale in Bootstrap that’s been designed to properly layer navigation, tooltips and popovers, modals, and more.
