    target="_blank"

    <div slot="description">10/15/18</div>
    <div slot="footer">Footer</div>
</sp-card>

Asset

When leveraging the asset attribute, a card can be declared as representing a file or a folder:

<sp-card heading="Card Heading" subheading="JPG Photo" asset="file">
    <div slot="heading">File Name</div>
    <div slot="description">10/15/18</div>
    <div slot="footer">Footer</div>
</sp-card>
<sp-card subheading="JPG Photo" asset="folder">
    <div slot="heading">Folder Name</div>
    <div slot="description">10/15/18</div>
    <div slot="footer">Footer</div>
</sp-card>

Toggles

When the toggles boolean attribute set to true, the card can be toggled between selected and unselected states. A checkbox will be rendered on hover, focus within, and when the card is selected.

<sp-card toggles variant="quiet" heading="Card Heading" subheading="JPG Photo">
    <img alt="" slot="preview" src="https://picsum.photos/200/350" />
    <div slot="description">10/15/18</div>
</sp-card>

Accessibility

Be concise

Heading text should be no more than 5-7 words. If the card has an href, the heading is used as a link and should ideally be no more than 3 words. For buttons, 1-2 words.

Use descriptive heading, link, and button text

Be descriptive. Set expectations on what someone will find and where they will go once they interact with a card. Avoid using the same text on more than one interactive element, unless both elements go to the same place.

Make the first word in a heading meaningful

Consider making the first word of links, buttons and headings something an assistive technology user might search for when headings and links are listed alphabetically.
