Card
The card component provides a navigation mechanism consisting of a title and link, descriptive text and an optional list of further links.
<div class="ons-card" aria-labelledBy="title" aria-describedBy="text">
<h3 class="ons-u-fs-m" id="title">

When to use this component
Use the card component to signpost users to pages and to provide context and further information on the contents of the destination page.
Good examples of where the use of cards work well include; the homepage, to create a collection of the main areas of the service and provide further affordance of what the service offers; hub level pages, to show the key content areas of what could be a deep structure; as a consistent pattern of navigation at any level within a site structure.
How to use this component
Cards should be used in the main container of the page and not within side bars, footers etc. The card component needs to be implemented using the ons-grid component and the various layout options available to display cards in rows. A row should contain no more than 3 or 4 cards and stack vertically on small viewports.
The html tab shows the various classes used to achieve the layout.

How to use this component
If using the card pattern with images, we have two versions of the image, one for standard screens and the other for retina screens.
Image dimensions (width × height):
- standard screen is:
303px × 200px - retina screen is:
606px × 400px
We specify a small and a large image path, which is defined in the macro as smallSrc and largeSrc.
