Twitter Card display on desktop
Generate inline content previews on Twitter.com and Twitter clients by including Twitter Card HTML meta elements for individual posts.
All cards are a Twitter Card summary by default. Tap into the twitter_card_properties filter to reference the Twitter accounts of your site or author.
Test your site’s Twitter Card display through Twitter’s card preview tool.
twitter_cards_properties – act on an array of properties before they are output to the pagetwitter_cards_htmlxml – override the default treatment of html with xml. XML will self-close the meta void element ( “” vs. “” )
