Generate inline content previews on Twitter.com and Twitter clients by including <a href="https://dev.twitter.com/docs/cards" rel="nofollow ugc">Twitter Card</a> HTML meta elements for individual posts.
All cards are a Twitter Card summary by default. Tap into the <code>twitter_card_properties</code> filter to reference the Twitter accounts of your site or author.
Test your site’s Twitter Card display through <a href="https://dev.twitter.com/docs/cards/preview" rel="nofollow ugc">Twitter’s card preview tool</a>.
