Border

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

Additive

{% capture example %} {% endcapture %} {% include example.html content=example %}

Subtractive

{% capture example %} {% endcapture %} {% include example.html content=example %}

Border color

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

{% capture example %} {% for color in site.data.theme-colors %} {% endfor %} {% endcapture %} {% include example.html content=example %}

Border-radius

Add classes to an element to easily round its corners.

{% highlight html %} {% endhighlight %}
