Calculate the position of an element relative to another element or event. Tries to find a collision free position within the viewport of a given container.
Download the production version or the development version or install it via Bower.
or for quick tests, add this tag to load it direct from github:
<script src="http://tlindig.github.io/position-calculator/dist/position-calculator.min.js"></script>
I will deploy it on CDN "cdnJS.com" if this requirement is met:
Libraries must have notable popularity: 100 stars or watchers on GitHub is a good example, but as long as reasonable popularity can be demonstrated the library will be added."
Visit demonstration and documentation page: Position Calculator
Ready to use version of this lib can be found in folder: "dist"
