A layout component for web apps


The .ds-app component provides the layout/arrangement of a web app.

Basic usage 

The basic building blocks of ds-app are as follows:

Class Required? Description
ds-app The top-most level container.
ds-app__header The container for the header component.
ds-app__notice Optional The container for notice content.
ds-app__breadcrumb Optional The container for the breadcrumb component.
ds-app__main The container for the main content of the page.
ds-app__main-title Recommended The app title panel. This panel will disappear when scrolling.
ds-app__main-controls Optional A panel to contain the main controls. This panel will stick to the top when scrolling.
ds-app__main-content A panel to contain the main page content. This panel will scroll automatically.
ds-app__footer Optional A panel for footer content.


A notice directly inside ds-app “should” always appear directly under the header and will be pinned with the header and not scroll off the page.

A notice inside ds-app__main will appear based on the source code order and will scroll when the main content scrolls.

The recommend structure for notices is (see Notice - pinned style and Notice - strong color):

<div class="ds-notice--alert ds-notice--pinned ds-notice--strong">
  An example alert notice
XS Mobile 320px Mobile 420px Tablet 680px Desktop 960px
<div class="ds-notice--alert ds-notice--pinned ds-notice--strong">
  An example alert notice
