/**
* @ngdoc directive
* @name mdContent
* @module material.components.content
*
* @restrict E
*
* @description
*
* The `<md-content>` directive is a container element useful for scrollable content. It achieves
* this by setting the CSS `overflow` property to `auto` so that content can properly scroll.
*
* In general, `<md-content>` components are not designed to be nested inside one another. If
* possible, it is better to make them siblings. This often results in a better user experience as
* having nested scrollbars may confuse the user.
*
* ## Troubleshooting
*
* In some cases, you may wish to apply the `md-no-momentum` class to ensure that Safari's
* momentum scrolling is disabled. Momentum scrolling can cause flickering issues while scrolling
* SVG icons and some other components.
*
* Additionally, we now also offer the `md-no-flicker` class which can be applied to any element
* and uses a Webkit-specific filter of `blur(0px)` that forces GPU rendering of all elements
* inside (which eliminates the flicker on iOS devices).
*
* _<b>Note:</b> Forcing an element to render on the GPU can have unintended side-effects, especially
* related to the z-index of elements. Please use with caution and only on the elements needed._
*
* @usage
*
* Add the `[layout-padding]` attribute to make the content padded.
*
* <hljs lang="html">
* <md-content layout-padding>
* Lorem ipsum dolor sit amet, ne quod novum mei.
* </md-content>
* </hljs>
