## Border

Use border utilities to add or remove an element's borders. Choose from all borders or one at a time.

### Additive

<div class="bd-example-border-utils">
{% capture example %}
<span class="border"></span>
<span class="border-top"></span>
<span class="border-right"></span>
<span class="border-bottom"></span>
<span class="border-left"></span>
{% endcapture %}
{% include example.html content=example %}
</div>

### Subtractive

<div class="bd-example-border-utils bd-example-border-utils-0">
{% capture example %}
<span class="border-0"></span>
<span class="border-top-0"></span>
<span class="border-right-0"></span>
<span class="border-bottom-0"></span>
<span class="border-left-0"></span>
{% endcapture %}
{% include example.html content=example %}
</div>

## Border color

Change the border color using utilities built on our theme colors.

<div class="bd-example-border-utils">
{% capture example %}
{% for color in site.data.theme-colors %}
<span class="border border-{{ color.name }}"></span>{% endfor %}
<span class="border border-white"></span>
{% endcapture %}
{% include example.html content=example %}
</div>

## Border-radius

Add classes to an element to easily round its corners.

<div class="bd-example bd-example-images">
  {%- include icons/placeholder.svg width="75" height="75" class="rounded" title="Example rounded image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-top" title="Example top rounded image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-right" title="Example right rounded image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-bottom" title="Example bottom rounded image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-left" title="Example left rounded image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-circle" title="Completely round image" -%}
  {%- include icons/placeholder.svg width="150" height="75" class="rounded-pill" title="Rounded pill image" -%}
  {%- include icons/placeholder.svg width="75" height="75" class="rounded-0" title="Example non-rounded image (overrides rounding applied elsewhere)" -%}
</div>

{% highlight html %}
<img src="..." alt="..." class="rounded">
<img src="..." alt="..." class="rounded-top">
<img src="..." alt="..." class="rounded-right">
<img src="..." alt="..." class="rounded-bottom">
<img src="..." alt="..." class="rounded-left">
<img src="..." alt="..." class="rounded-circle">
<img src="..." alt="..." class="rounded-pill">

{% endhighlight %}
