With the current docs directory setup, I'm making too many mistakes and have to manually address path changes and directory moves on deploy. This makes for a frustrating experience developing locally and shipping releases. With this PR, we're basically back to the same setup from v3—duplicating the dist directory into our docs directory. Not the most ideal, but very straightforward for me as the release manager.

## Changing `display`
|
|
|
|
Use our [display utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/) 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]({{ site.baseurl }}/docs/{{ site.docs_version }}/components/alerts/) 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]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/flex/) for sizing, alignment, spacing, and more.
|
|
|
|
## Margin and padding
|
|
|
|
Use the `margin` and `padding` [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/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]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/visibility/). Invisible elements will still affect the layout of the page, but are visually hidden from visitors.
