Differences between this plugin and jQuery.marquee

Although this plugin can be a drop in replacment for the jQuery plugin there are some caveats, which may be deal breaking:

• allowCss3Support and easing options have been removed (all animations use the @keyframe implementation)
• pauseOnCycle option has been removed, since it was available only when allowCss3Support was set to false
• no IE and dead browser support, since we are in $currentYear I don't think it's necessary
• this module is not transpiled for old browsers, you can transpile it yourself: example with rollup and babel

babel({
  babelHelpers: 'bundled',
  exclude:      '/node_modules/',
  include: [
    'src/**', // src folder
    /node_modules\/.+(vanilla-marquee|matt-utils)/,
  ]
}),

• the methods can only be called with instance.method(), in the jQuery version they can be called using $( selector ).marquee( 'methodName' )
• events are fired on the selector rathen than the instance

Options

Option	Default	Description
css3easing	'linear'	a css3 transtion timing
delayBeforeStart	1000	Time in ms before the marquee starts animating
direction	'left'	Direction towards which the marquee will animate 'left', 'right', 'up', 'down'
duplicated	false	Should the marquee be duplicated to show an effect of continuous flow. Use this only when the text is shorter than the container
duration	5000	Duration in ms in which you want your element to travel
speed	0	Speed will override duration. Speed allows you to set a relatively constant marquee speed regardless of the width of the containing element. Speed is measured in pixels/second
gap	20	Gap in pixels between the tickers. Will work only when the duplicated option is set to true. Note: 20 means 20px so no need to use '20px' as the value.
pauseOnHover	false	Pause the marquee on hover.
startVisible	false	The marquee will be visible from the start if set to true.
recalcResize	false	Should the marquee be updated on resize.

Methods

Name	Description
pause	To pause the marquee at any time.
resume	To resume the marquee after being paused previously.
toggle	To toggle between pause and resume methods.
destroy	To remove the marquee and all attached events from your element. This method is useful if you are loading/changing the data using Ajax or just another string. You can combine this with the finished event so you can have the marquee show some data and as soon as it finishes showing that, you can destroy it, change the html and then apply the plugin again.
refresh	Recalcs the marquee size and position. Works like the recalcResize but is triggered manually instead of on window resize.

Events:

Name	Description
beforeStarting	Event will be fired on the element before animation starts.
finished	Event will be fired on the element on each iteration of the animation when it finishes.
paused	Event will be fired on the element when the animation is paused.
resumed	Event will be fired on the element when the animation is resumed.
