Using the Modal from Regular Labs gives you the opportunity to extend your content, image, video, or an external link into a popup that displays it.

The word Modal implies "relating to mode or form as opposed to substance", and this is actually what it does. The Extension Modal from Regular Labs is useful for displaying pop-up content on your page. We use it for our articles, to display information about the author.

Some of Modals features

• Image modal
  If you have an image that is large, you can use this extension to popup a larger image of the displayed _thumbmail. This is very useful when dealing with large images with high contrast, you can then easily connect the image to a modal and have the user click for a larger version (See the image on right). 
• Popup external links
  This feature is handy if you have links to external sites, but don't want the reader to leave your site. (You cannot open non-SSL (http) urls inside a SSL (https) website, nor can you  open SSL (https) urls inside a non-SSL (http) website).
• Create an image gallery
  With Modal, you can easily insert a image gallery.
• Link content directly
  If you don't want to create an article for your content, you can simply create it on the fly
• Articles
  If you in the other hand has created an article, and want to display it in a popup, you can do so
• Display Videos
  You can easily include videos from sites like YouTube, Vimeo, and others in a popup window when the reader clicks a link.
• Auto-load
  The Auto-load can be used for popups when someone enters a page. (Auto Popups are annoying, and not recommendable)
