Dealing with specificity

-

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.

To align components in navbars with utility classes, use .navbar-left or .navbar-right instead. See the navbar docs for details.

They can also be used as mixins. - -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. - -{% highlight html %} -
