AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

How to make faster scroll effects?

• Avoid too many reflows (the browser to recalculate everything)
• Use advanced CSS3 for graphic card rendering
• Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

Skateside

// Detects whether or not a given CSS selector is supported by the current
// browser.
//
//        Takes:
//            selector (String)     The CSS selector to test.
//        Returns:
//            (Boolean)             true if the selector is supported, false
//                                  otherwise.
var supportsSelector = (function () {

# the javascript.

# Usage: ruby pnginator.rb input.js output.png.html
