Below is a primer on what's included in Bootstrap and how these utilities can help you with layout. + +## Contents + +* Will be replaced with the ToC, excluding the "Contents" header +{:toc} + +## Changing `display` + +Use our `display` utilities for responsively toggling common values of the `display` property. Mix it with our grid system, content, or components to show or hide them across specific viewports. + +## Flexbox options + +Bootstrap 4 is built with flexbox, but not every element's `display` has been changed to `display: flex` as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of [our components](/components/) are built with flexbox enabled. + +Should you need to add `display: flex` to an element, do so with `.d-flex` or one of the responsive variants (e.g., `.d-sm-flex`). You'll need this class or `display` value to allow the use of our extra [flexbox utilities](/utilities/flexbox/) for sizing, alignment, spacing, and more. + +## Margin and padding + +Use the `margin` and `padding` [spacing utilities](/utilities/spacing/) to control how elements and components are spaced and sized. Bootstrap 4 includes a five-level scale for spacing utilities, based on a `1rem` value default `$spacer` variable. Choose values for all viewports (e.g., `.mr-3` for `margin-right: 1rem`), or pick responsive variants to target specific viewports (e.g., `.mr-md-3` for `margin-right: 1rem` starting at the `md` breakpoint). + +## Toggle `visibility` + +When toggling `display` isn't needed, you can toggle the `visibility` of an element with our [visibility utilities](/utilities/visibility/). Invisible elements will still affect the layout of the page, but are visually hidden from visitors. |
