Scroll Triggered Boxes


Scroll Triggered Boxes

Scroll Triggered Boxes is a lightweight plugin for adding flexible call-to-actions to your WordPress site. Boxes can slide or fade in at any point and can contain whatever content you like.

This plugin is the predecessor of the Boxzilla Plugin, which you should use instead.


  • Create boxes containing whatever content you like: shortcodes, links, custom HTML, anything really.
  • Show boxes automatically after scrolling down based on a percentage point or a certain element (like your comment section).
  • Show boxes using a button or link.
  • Choose the box position: centered or in any corner of the screen.
  • Choose between a fading or sliding animation for showing the box.
  • Customize the box appearance using a few simple color & dimension controls.
  • Only load the box on certain pages, posts, etc.
  • Control how long dismissed boxes should stay hidden.
  • Control whether boxes should show on small screens.

In May 2016, this plugin was replaced by Boxzilla, which is also available on the plugin repository.

Installation Instructions

This plugin has been replaced by Boxzilla. It is highly recommended you use that instead.

Should I use this or Boxzilla?

We are no longer actively pushing out new features to this plugin, so it highly recommended you use the Boxzilla Plugin instead.

What does this plugin do?

Have a look at the Scroll Triggered Boxes demo site.

How to display a form in the box?

The plugin is battle-tested with the plugins below but will work with any plugin that uses shortcodes.

How to display sharing options in the box?

The plugin is tested with the plugins below but will work with any plugin that uses shortcodes.

How do I set more advanced rules for on which pages to show a box?

You can use conditional tags to set super-customized rules.

Example: only show for posts in category ‘cars’

is_single() && in_category( 'cars' )

*Example: show everywhere except on pages with slug ‘contact’ and ‘checkout’

! is_page( array( 'contact', 'checkout' ) )
Can I have a box to open after clicking a certain link or button?

Sure, just link to the box element.

Example (box ID is 94 in this example)

<a href="#stb-94">Open Box</a>
Can I have a box to open right after opening a page?

Sure, just include stb- followed by the box ID in the URL.

Example (box ID is 94 in this example)
How to set more advanced styling rules

If you want more advanced styling, you can use CSS to further style the boxes. Every box gets its own unique #id as well as various CSS classes.

.stb-{id} { } /* 1 particular box */
.stb { } /* all boxes */
.stb-close{ } /* the close button of the box */
I want to disable auto-paragraphs in the box content

All default WordPress filters are added to the stb_content filter hook. If you want to remove any of them, add the respectable line to your theme its functions.php file.

remove_filter( 'stb_box_content', 'wptexturize') ;
remove_filter( 'stb_box_content', 'convert_smilies' );
remove_filter( 'stb_box_content', 'convert_chars' );
remove_filter( 'stb_box_content', 'wpautop' );
remove_filter( 'stb_box_content', 'do_shortcode' );
remove_filter( 'stb_box_content', 'shortcode_unautop' );
I want to disable closing of the box

add_filter( ‘stb_box_options’, function( $opts ) {
$opts[‘unclosable’] = true;
return $opts;



its good
but please clear the documentation a little bit.

Amazing & Superb

Pop-up are greatly needed for any website, this plugin provides you the most convinient way of implementing it ! Hassle free…. Kudos to the plugin team !


I thought I would have to implemente my own system to display a box in a corner in some pages….

Most of this “call to action” plugins take over the page or need a short codes to appear….

Note: My adblocker was blocking the box and took me some time to discover that problem…. You guys could add a note about that in Settings page!

Thanks for creating this plugin!
