// Animate a set of properties of an element
|
|
//# element - the element to be moved (optional
|
|
//# duration - duration of animation
|
|
//# properties - an array of objects describing each property that is to be modified:
|
|
//# format - one of:
|
|
//# "style" for numeric styles (default)
|
|
//# "color" for #RRGGBB format colour styles
|
|
//# style - name of the style being animated. Includes pseudo-styles:
|
|
//# "-tw-scrollVert" - controls vertical scrolling
|
|
//# "-tw-scrollHoriz" - controls horizontal scrolling
|
|
//# start - starting value to animate from
|
|
//# end - ending value to animation from
|
|
//# atEnd - final value (taking priority over the end value) (eg, for switching style.display)
|
|
//# template - template for formatString() for setting the property (eg "%0em", or "#%0")
|
|
//# callback - function to call when the animation has completed as callback(element,properties);
