Infinite-Scroll

Infinite scroll has been called autopagerize, unpaginate, endless pages. But essentially it is pre-fetching content from a subsequent page and adding it directly to the user’s current page.

When a user scrolls towards the bottom of the page, the next page of posts is automatically retrieved and appended. This means they never need to click ”Next Page”, which dramatically increases stickiness.

Features:

• Works out-of-the-box for many popular WordPress themes — just activate the plugin and scroll
• Fully customizable to adapt to your site and theme
• Requires no (hopefully) template hacking, only a knowledge of CSS selectors.
• Relies on shared database of common themes to simplify installation process
• Maintain local database of theme presets for all installed themes (shared across network on multisite installs)
• Countless API endpoints to modify the behavior.
• Backwards compatible: Will not break RSS readers, mobile devices, or browsers with javascript
