## Auto margins ## Auto margins
Flexbox can do some pretty awesome things when you mix `justify-content` with `margin-right: auto` or `margin-left: auto` on a particular flex item. For example, we can move all flex items to the right, but keep one on the left like so. Flexbox can do some pretty awesome things when you mix flex alignments with auto margins.
### With justify-content
Easily move all flex items to one side, but keep another on the opposite end by mixing `justify-content` with `margin-right: auto` or `margin-left: auto`.
{% example html %} {% example html %}
<div class="d-flex justify-content-end bd-highlight"> <div class="d-flex justify-content-end bd-highlight mb-3">
<div class="mr-auto p-2 bd-highlight">Flex item</div> <div class="mr-auto p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div> <div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div> <div class="p-2 bd-highlight">Flex item</div>
</div> </div>
<div class="d-flex justify-content-start bd-highlight">

<div class="p-2 bd-highlight">Flex item</div>
<div class="ml-auto p-2 bd-highlight">Flex item</div>
</div>

Similarly, move one flex item to the top or bottom of a container by mixing `align-items`, `flex-direction: column`, and `margin-top: auto` or `margin-bottom: auto`.
{% example html %}
<div class="d-flex align-items-start flex-column bd-highlight mb-3" style="height: 200px;">
<div class="mb-auto p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
</div>
<div class="d-flex align-items-end flex-column bd-highlight mb-3" style="height: 200px;">
<div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
<div class="mt-auto p-2 bd-highlight">Flex item</div>
</div>
