myAlert
myAlert is a very simple Js library that can display callout dialogs anywhere on a HTML page. It's very lightweight in its filesize and performance. The lib depends on only two other popular libs which are: jQuery & iscroll, and it is still open for other cool implementations. So, any contribution will be welcome. I hope you like it.
I use myAlert to create this chrome extension: https://chrome.google.com/webstore/detail/jhehenajiifngcndnlecbmcdobnkeglb
