Convey meaning through color with a handful of emphasis utility classes. These may also be applied to links and will darken on hover just like our default link styles.
Fusce dapibus, tellus ac cursus commodo, tortor mauris nibh.
Nullam id dolor id nibh ultricies vehicula ut id elit.
Duis mollis, est non commodo luctus, nisi erat porttitor ligula.
Maecenas sed diam eget risus varius blandit sit amet non magna.
Etiam porta sem malesuada magna mollis euismod.
Donec ullamcorper nulla non metus auctor fringilla.

{% endhighlight %}Sometimes emphasis classes cannot be applied due to the specificity of another selector. In most cases, a sufficient workaround is to wrap your text in a <span>
with the class.
Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (the contextual colors are only used to reinforce meaning that is already present in the text/markup), or is included through alternative means, such as additional text hidden with the .sr-only
class.
Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes.

{% endhighlight %}Sometimes contextual background classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a <div>
with the class.
As with contextual colors, ensure that any meaning conveyed through color is also conveyed in a format that is not purely presentational.
Use the generic close icon for dismissing content like modals and alerts.
Use carets to indicate dropdown functionality and direction. Note that the default caret will reverse automatically in dropup menus.
Float an element to the left or right with a class. !important
is included to avoid specificity issues. Classes can also be used as mixins.
Set an element to display: block
and center via margin
. Available as a mixin and class.
Easily clear float
s by adding .clearfix
to the parent element. Utilizes the micro clearfix as popularized by Nicolas Gallagher. Can also be used as a mixin.
Force an element to be shown or hidden (including for screen readers) with the use of .show
and .hidden
classes. These classes use !important
to avoid specificity conflicts, just like the quick floats. They are only available for block level toggling. They can also be used as mixins.
.hide
is available, but it does not always affect screen readers and is deprecated as of v3.0.1. Use .hidden
or .sr-only
instead.
Furthermore, .invisible
can be used to toggle only the visibility of an element, meaning its display
is not modified and the element can still affect the flow of the document.
Hide an element to all devices except screen readers with .sr-only
. Combine .sr-only
with .sr-only-focusable
to show the element again when it's focused (e.g. by a keyboard-only user). Necessary for following accessibility best practices. Can also be used as mixins.
Utilize the .text-hide
class or mixin to help replace an element's text content with a background image.
