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.

## Example
|
|
|
|
The [media object](http://www.stubbornella.org/content/2010/06/25/the-media-object-saves-hundreds-of-lines-of-code/) helps build complex and repetitive components where some media is positioned alongside content that doesn't wrap around said media. Plus, it does this with only two required classes thanks to flexbox.
|
|
|
|
Below is an example of a single media object. Only two classes are required—the wrapping `.media` and the `.media-body` around your content. Optional padding and margin can be controlled through [spacing utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/spacing/).

{% capture example %}
|
|
<div class="media">
|
|
<img class="mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Media heading</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.

##### Flexbug #12: Inline elements aren't treated as flex items
|
|
|
|
Internet Explorer 10-11 do not render inline elements like links or images (or `::before` and `::after` pseudo-elements) as flex items. The only workaround is to set a non-inline `display` value (e.g., `block`, `inline-block`, or `flex`). We suggest using `.d-flex`, one of our [display utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/display/), as an easy fix.

## Nesting
|
|
|
|
Media objects can be infinitely nested, though we suggest you stop at some point. Place nested `.media` within the `.media-body` of a parent media object.
|
|
|
|
{% capture example %}
|
|
<div class="media">
|
|
<img class="mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Media heading</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
|
|
|
|
<div class="media mt-3">
|
|
<a class="pr-3" href="#">
|
|
<img data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
</a>
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Media heading</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
|
|
</div>

{% endcapture %}

{% include example.html content=example %}
|
|
|
|
## Alignment
|
|
|
|
Media in a media object can be aligned with flexbox utilities to the top (default), middle, or end of your `.media-body` content.
|
|
|
|
{% capture example %}
|
|
<div class="media">
|
|
<img class="align-self-start mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Top-aligned media</h5>
|
|
<p>Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.</p>
|
|
<p>Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p>
|
|
</div>
|
|
</div>
|
|
{% endcapture %}
|
|
{% include example.html content=example %}
|
|
|
|
{% capture example %}
|
|
<div class="media">
|
|
<img class="align-self-center mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Center-aligned media</h5>
|
|
<p>Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.</p>
|
|
<p class="mb-0">Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p>
|
|
</div>
|
|
</div>
|
|
{% endcapture %}
|
|
{% include example.html content=example %}
|
|
|
|
{% capture example %}
|
|
<div class="media">
|
|
<img class="align-self-end mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0">Bottom-aligned media</h5>
|
|
<p>Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.</p>
|
|
<p class="mb-0">Donec sed odio dui. Nullam quis risus eget urna mollis ornare vel eu leo. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.</p>
|
|
</div>
|
|
</div>
|
|
{% endcapture %}
|
|
{% include example.html content=example %}
|
|
|
|
## Order
|
|
|
|
Change the order of content in media objects by modifying the HTML itself, or by adding some custom flexbox CSS to set the `order` property (to an integer of your choosing).
|
|
|
|
{% capture example %}
|
|
<div class="media">
|
|
<div class="media-body">
|
|
<h5 class="mt-0 mb-1">Media object</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
|
|
</div>
|
|
<img class="ml-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
</div>
|
|
{% endcapture %}
|
|
{% include example.html content=example %}
|
|
|
|
## Media list
|
|
|
|
Because the media object has so few structural requirements, you can also use these classes on list HTML elements. On your `<ul>` or `<ol>`, add the `.list-unstyled` to remove any browser default list styles, and then apply `.media` to your `<li>`s. As always, use spacing utilities wherever needed to fine tune.
|
|
|
|
{% capture example %}
|
|
<ul class="list-unstyled">
|
|
<li class="media">
|
|
<img class="mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0 mb-1">List-based media object</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
|
|
</div>
|
|
</li>
|
|
<li class="media my-4">
|
|
<img class="mr-3" data-src="holder.js/64x64" alt="Generic placeholder image">
|
|
<div class="media-body">
|
|
<h5 class="mt-0 mb-1">List-based media object</h5>
|
|
Cras sit amet nibh libero, in gravida nulla. Nulla vel metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
