The .invisible class 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 scss %} // Class .invisible { visibility: hidden; }

// Usage as a mixin .element { @include invisible; } {% endhighlight %}
