 - Clicking on the modal "backdrop" will automatically close the modal.
 - Bootstrap only supports one modal window at a time. Nested modals aren't supported as we believe them to be poor user experiences.
 - Modals use `position: fixed`, which can sometimes be a bit particular about its rendering. Whenever possible, place your modal HTML in a top-level position to avoid potential interference from other elements. You'll likely run into issues when nesting a `.modal` within another fixed element.

 ## HTML5 `[hidden]` attribute

-HTML5 adds [a new global attribute named `[hidden]`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/hidden), which is styled as `display: none` by default. Borrowing an idea from [PureCSS](http://purecss.io), we improve upon this default by making `[hidden] { display: none !important; }` to help prevent its `display` from getting accidentally overridden. While `[hidden]` isn't natively supported by IE10, the explicit declaration in our CSS gets around that problem.

---
-
-For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.
-
-Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation.
-
-## Contents
-
-* Will be replaced with the ToC, excluding the "Contents" header
-{:toc}
-
-##  Available classes
-
-* The `.hidden-*-up` classes hide the element when the viewport is at the given breakpoint or wider. For example, `.hidden-md-up` hides an element on medium, large, and extra-large viewports.
-* The `.hidden-*-down` classes hide the element when the viewport is at the given breakpoint or smaller. For example, `.hidden-md-down` hides an element on extra-small, small, and medium viewports.
-* There are no explicit "visible"/"show" responsive utility classes; you make an element visible by simply not hiding it at that breakpoint size.
-* You can combine one `.hidden-*-up` class with one `.hidden-*-down` class to show an element only on a given interval of screen sizes. For example, `.hidden-sm-down.hidden-xl-up` shows the element only on medium and large viewports. Using multiple `.hidden-*-up` classes or multiple `.hidden-*-down` classes is redundant and pointless.
-* These classes don't attempt to accommodate less common cases where an element's visibility can't be expressed as a single contiguous range of viewport breakpoint sizes; you will instead need to use custom CSS in such cases.

+description: Use any of our dozens of responsive utility classes for showing, hiding, aligning, and spacing content.
+group: layout
+---
+
+For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content. 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.
