Smart-Content-Placer

A small JavaScript class to programmatically position difficult content. What do I mean by that? Well lets assume you have many images which are different widths and heights. How do you place them on a page such that there are no "gaps"? This is basically a constrained bin packing problem. Using just CSS this is a no go as you will end up with blocks of whitespace appearing, thus some JavaScript is required. This little component allows for variable width and height content - imagine Pinterest on steroids (Pinterest only allows for variable height).

Browser Support

Key features

  • Fully responsive (up to the largest element width used).
  • Allows for variable width AND height content. All content must be a multiple of a base unit size.
  • Works with any type of responsive content (not just images).
  • Supports margins between content.
  • Works in all modern browsers.
  • Supports transitions for initial display and for fluid repositioning of content.
  • Requires no 3rd party libraries to work - pure native JavaScript.
  • Lightweight and efficient.
  • Fully customizable - all transitions / style is defined via CSS.

Why does this exist?

After a quick Google it seemed many other existing solutions required some third party library to work (jQuery), or were not as efficient as I wanted. I therefore decided to roll my own from a blank canvas to keep it as lightweight and efficient as possible.

Browser support

All popular browsers supported. Chrome, Firefox, Safari, Opera, Internet Explorer 9+ and I have tested on Android/iOS which seems to be fine too. Browser Support
