+### Hidden elements
 
-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](#helper-floats). They are only available for block level toggling. They can also be used as mixins.
+Hide any HTML element with the `[hidden]` attribute. Previously, v3.x included a `.hidden` class that forced toggled content. However, we removed it due to conflicts with jQuery's `hide()` function. It's taken from [PureCSS](http://purecss.io).
 
-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.
