Overview

Slidr is a clean, simple, responsive and touch-friendly multi-purpose Carousel. It takes a different approach than most other carousel plugins on that it displays posts or custom posts instead of just gallery photos (but it can show gallery photos as well if you like). Its goal is to be as flexible as possible, allowing you to fully customize its appearance via CSS and override the default HTML output. You can even use it as a “vessel” to display your custom loops which could, practically, contain any content you like, from YouTube videos and Google Maps to Instagram feeds and Tweets!
