Button Shortcode
Adds a [button] shortcode that turns a link into a styled button using your theme's button styles, for calls to action inside classic content and widgets.
Snippet Library
Content snippets for WordPress
Snippets that add to or change your posts and pages: reading time, author boxes, “last updated” notes, content after the post or after a paragraph, and excerpt tweaks. For bloggers, publishers and anyone who wants richer posts without editing theme files.
Post Title, Date and Author Shortcodes
Adds [post_title], [post_date], [post_modified], [post_author] and [post_url] shortcodes for templates, patterns and widgets that need details of the current post.
