Sequence - The Responsive Slider with Advanced CSS3 Transitions

Sequence provides the complete functionality for a website slider without forcing you to use a set theme. In fact, Sequence has no in-built theme, leaving you complete creative control to build a unique slider using only CSS3 -- no jQuery knowledge required!


  • Unique transition styles created using CSS3
  • Supports all modern browsers
  • Gracefully degrades in older browsers*
  • Supports responsive layouts
  • Supports touch devices and swiping
  • Many developer features with even more to come
  • Semantic and easy to use markup
  • Open source

*Tested down to Firefox 3.6 and IE7. Extensive support details to come.

What's New?

v0.7.5.1 13/11/2012

  • Minor fixes

v0.7.5 13/11/2012

  • It's now possible to skip frames whilst they are animating. Finally!
  • Added new options relating to navigation skipping: navigationSkip, navigationSkipThreshold, fadeFrameWhenSkipped, fadeFrameTime, and preventReverseSkipping
  • Removed transitionThreshold option. One frame can now only animate in immediately after the other. Nobody seemed to use this option and its presence affected the new navigation skipping options. If you want a time period between one frame animating out and the next frame animating in, use a CSS transition-delay instead
  • Removed defunct code and general tidy up

v0.7.4.1 01/11/2012

Note: If upgrading from an existing Sequence.js version and using a preloader, please add preloader: true to your options

  • Changed the preloader option to false by default.

v0.7.4 31/10/2012

  • Now works with jQuery 1.8.2
  • Rewritten autoPlay logic, which is now much simpler and easier to maintain
  • Added .unpause() function for clarity (.pause() will still toggle between pause and unpause for backwards compaitibility)
  • Added isHardPaused public variable. isHardPaused is set to true when Sequence is paused via the pause button. You can also pass an argument of true when using the .pause(true) public method to manually set isHardPaused to true
  • The transitionThreshold setting now works when animateStartingFrameIn is true
  • Fixed keyboard events. Pressing numeric keys will now navigate to respective frames. Custom key events are also working
  • Removed pauseOnElementsOutsideContainer setting. Seemed to have been broken for a while and nobody noticed so decided it was useless!
  • Added more inline documentation to the non minified version -- more to come!

v0.7.3 16/09/2012

  • Preloader should now work perfectly in all browsers

v0.7.2 13/09/2012

Note: 0.7.2 may not be backwards compatible with existing themes if those themes use callbacks or the public variable paused, which has now been renamed to isPaused. Please see the documentation for how callbacks now work and update your theme accordingly.

  • Preloader now more stable (although still not perfect, will be fixed in 0.7.3)
  • Change how callbacks work to be more intuitive and work around IE issues
  • Updated themes to work with new callback method

v0.7.1 21/08/2012

v0.7.0.1 17/08/2012

  • Minor fix to prevent frames from being able to animate in before another frame has finished animating (when the transitionThreshold is greater than the animation time).

v0.7 16/08/2012

  • Added preloadTheseFrames and preloadTheseImages options. Previously, when the preloader option was true, Sequence wouldn't initiate until the entire page had loaded. By giving the preloadTheseFrames option a comma separated list of frame numbers, you can tell Sequence which images need to be loaded before Sequence initiates. The preloadTheseImages can be given a comma separated list of image paths that tells Sequence to only initiate once those images have loaded. If you'd like, you can combine these options to have all images in frame 1 and one image from frame 2 to load before Sequence initiates.

v0.6.9 14/08/2012

  • Added moveActiveFrameToTop option that will bring an active frame to the top via z-index
  • Dropped Opera 11 down to fallback theme support due to it's poor implementation of CSS3 transitions
  • Made adding UI elements simpler (which reduced a lot of code too)
  • The default preloader icon now uses SVG - no more 404s for the preloader image!
  • General fixes and tidy up

v0.6.8 10/07/2012

  • Added "Slide" fallback theme and made it the default. "Slide" provides better support for older versions of Internet Explorer because opacity is no longer needed. In the original "Fade" fallback, opacity was used which caused a black halo around PNGs.
  • Added new option hideFramesUntilPreloaded, which is true by default. When true, frames will be hidden as soon as Sequence is loaded and then shown when everything has preloaded.
  • Lots of changes made to the themes to better assist with Internet Explorer support. Also removed CSS Resets into their own files to make themes a little more modular.

v0.6.7.1 19/06/2012

  • Minor fix to get Sequence working in Opera 12

v0.6.7 5/06/2012

Note: 0.6.7 may not be backwards compatible with existing themes if those themes use the afterPreload callback, which has now been renamed to afterLoaded

  • Fixed bug that prevented Sequence from initiating when the preloader was disabled
  • Changed the name of the afterPreload callback to afterLoaded and made it execute whether a preloader is used or not
  • Changed the name of the FallbackTheme object to fallback. fallback now has an option within it called theme. In the future, the theme option can be given different strings such as fade and slide to provide different fallback themes for older browsers.
  • A few minor adjustments to improve or remove redundant code

v0.6.6 16/05/2012

Bug fix for Multiple Instances of Sequence

The documentation has been slightly modified to better assist with multiple instances of Sequence on the same page. The default Sequence preloader was originally appended to the Sequence container as an ID but this caused issues when using more than one Sequence instance, so it's now a class.

v0.6.5 14/05/2012

Note: 0.6.5 may not be backwards compatible with existing themes if those themes use the delayDuringOutInTransitions setting, which has now been renamed to transitionThreshold

New callback

You can now use afterCurrentFrameAnimatesOut which is triggered once the current frame reaches the end of its animate out transition

Minor changes to delayDuringOutInTransitions Setting

delayDurintOutInTransitions option renamed to transitionThreshold Fix for transitionThreshold which now makes all possible settings work

v0.6.4 09/05/2012

Minor changes to how the nextButton/prevButton/pauseButton and prependNextButton/prependPrevButton/prependPauseButton options work. Now closer match how they are described in the documentation.

v0.6.3 08/05/2012

Check out the updated Apple Style theme that showcases the new pause options and callbacks.

New Pause Options

pauseButton, prependPauseButton, pauseButtonSrc, pauseButtonAlt, unpauseDelay have been added to allow for a pause button when using autoPlay.

New Pause Callbacks

Two new callbacks added for pause and unpause

New customKeyEvent for Pausing

If using customKeyEvents, you can now hook a key to the pause event.

startAutoPlay Public Method Bug Fix

The public method startAutoPlay accepted an argument that would cause Sequence to wait x amount of milliseconds before autoPlay was started. This argument wasn't correctly implemented but should now work.

Sequence Container is Given a Class of "sequence-fallback" When in Fallback Mode

If Sequence goes into fallback mode because the browser doesn't support CSS3 transitions, it is given the class of "sequence-fallback" allowing for the application of styles specifically for older browsers

v0.6.2 06/05/2012

Note: 0.6.2 may not be backwards compatible with existing themes if those themes use the touchEnabled and keysNavigate settings (these settings have changed names, see below)

Added keyEvents Option

keyEvents allows you to specify which way the left and right arrows should cause Sequence to navigate. See Keyboard Options

Added customKeyEvents Option

customKeyEvents are keyEvents on steroids! Specify a key (using a keyCode) and the event to be trigger when the user hits that key. Example: 65: "prev" causes Sequence to navigate backwards when the "a" key is pressed on the keyboard.

Added numericKeysGoToFrames Option

When the keyboards numeric keys are pressed, if there is a frame that represents that number, Sequence will navigate to that frame.

Added swipeEvents Option

swipeEvents allows you to specify which way Sequence should navigate when the user swipes in a particular direction. Up/Down/Left/Right supported.

Added swipePreventsDefault Option

If set to true, on touch devices, when swiping over Sequence, the default will be prevented (the page will not scroll). Useful if you want up/down swiping to cause Sequence to navigate but be careful that this doesn't affect user experience by preventing scrolling the page all together.

Changed the Names of a Few Options

touchEnabled changed to swipeNavigation keysNavigate changed to keyNavigation

Tidied up the Documentation

Changed the layout of the options in the documentation

v0.6.1 03/05/2012

Bug Fix

In previous versions of Sequence, all frame elements HAD to have a class for Sequence to work. This was unintentional but is now resolved in 0.6.1. Use IDs and classes as you see fit, but they're no longer necessary.

v0.6 03/05/2012

Code Optimisation and General Tweaks

Note: 0.6 may not be backwards compatible with existing themes, particularly if they use before/after callbacks or rely on the "current" class

  • A frame is now only deemed as being "current" when it is in the viewport but not animating. If animating in, it will have a class of "next-frame". The "current" frame now has a class of "current-frame".

  • Changed the before/after callbacks. These callbacks are now beforeNextFrameAnimatesIn, afterNextFrameAnimatesIn, beforeCurrentFrameAnimatesOut. Please consult the documentation and the to better understand this.

  • before/after callbacks are now working correctly in the fallback themes.

Fix for Reversed Animation Speeds

If an element animates-in at 2 seconds and then animates-out at 3, when it reverses in (from the animate-out position), it will take 3 seconds.

v0.5.2 02/05/2012

Made 'Modern Slide In' Responsive

The theme 'Modern Slide In' is now responsive.

No changes made to Sequence.js.

v0.5.2 18/04/2012

Touch Swiping Improved

Swiping on touch devices has been improved and swipeThreshold is working again. Links within frames are clickable and the page can be scrolled vertically without initiating a frame change.

v0.5.1 17/04/2012

Changed Default Values for nextButton and prevButton

The nextButton and prevButton options are now turned off out of the box. To turn them on, either use the defaults by setting these options to true or by specifying a CSS selector to use your own custom buttons

v0.5 15/04/2012

Multiple Instances Now Working

Merged a pull request that got multiple instances of Sequence on one page working.

v0.4 11/03/2012

Previous/Next Button Options

The previous and next buttons now have a couple more options:

  • nextButtonSrc: specify a path to an image to be used as the next button
  • nextButtonAlt: specify a string to be used as the alt text for the next button image
  • prevButtonSrc: specify a path to an image to be used as the previous button
  • prevButtonAlt: specify a string to be used as the alt text for the previous button image


General tidy up of the script. Made some changes for better practice -- now only using one jQuery function etc, all dependencies are enclosed within the Sequence function. Also optimised .init().

v0.3 06/03/2012)

Modernizr Detect

Sequence will now detect whether Modernizr.prefixed is installed on the site, if it's not, it'll use its own instance.


Sequence will now only trigger the pause function when hovering over its child elements inside the container. If you'd like Sequence to pause when hovering on child elements outside of the container, set this to true.

pauseIcon Fix

In update v0.2, the pauseIcon option got broken. This is now fixed.

v0.2 28/02/2012


Sequence now has a default preloader or support for a custom preloader. When preloading is complete, a class of "preloading-complete" can be added to one or multiple elements to allow you to write your own reveal using CSS3 transitions. Also comes with a callback for when the preloading is complete.

Cycle Option

Choose whether Sequence should go back to the start when it reaches the last frame (or the first frame if navigating backwards)

reverseAnimationsWhenNavigatingBackwards Option

When navigating backwards, you can now specify whether frames should animate forwards or in reverse

Something went wrong with that request. Please try again.
