- This class is added to all slides that appear after the 'next' slide.
-
- options.classes.before
- This class is added to all slides that appear before the 'previous'
- slide.
-
- options.classes.childCurrent
- This class is added to all elements in the DOM tree between the
- 'current' slide and the deck container. For standard slides, this is
- mostly seen and used for nested slides.
-
- options.classes.current
- This class is added to the current slide.
-
- options.classes.loading
- This class is applied to the deck container during loading phases and is
- primarily used as a way to short circuit transitions between states
- where such transitions are distracting or unwanted. For example, this
- class is applied during deck initialization and then removed to prevent
- all the slides from appearing stacked and transitioning into place
- on load.
-
- options.classes.next
- This class is added to the slide immediately following the 'current'
- slide.
-
- options.classes.onPrefix
- This prefix, concatenated with the current slide index, is added to the
- deck container as you change slides.
-
- options.classes.previous
- This class is added to the slide immediately preceding the 'current'
- slide.
-
- options.selectors.container
- Elements matched by this CSS selector will be considered the deck
- container. The deck container is used to scope certain states of the
- deck, as with the onPrefix option, or with extensions such as deck.goto
- and deck.menu.
-
- options.selectors.slides
- Elements matched by this selector make up the individual deck slides.
- If a user chooses to pass the slide selector as the first argument to
- $.deck() on initialization it does the same thing as passing in this
- option and this option value will be set to the value of that parameter.
-
- options.keys.next
- The numeric keycode used to go to the next slide.
-
- options.keys.previous
- The numeric keycode used to go to the previous slide.
-
- options.touch.swipeDirection
- The direction swipes occur to cause slide changes. Can be 'horizontal',
- 'vertical', or 'both'. Any other value or a falsy value will disable
- swipe gestures for navigation.
-
- options.touch.swipeTolerance
- The number of pixels the users finger must travel to produce a swipe
- gesture.
-
- options.initLockTimeout
- The number of milliseconds the init event will wait for BeforeInit event
- locks to be released before firing the init event regardless.
-
- options.hashPrefix
- Every slide that does not have an id is assigned one at initialization.
- Assigned ids take the form of hashPrefix + slideIndex, e.g., slide-0,
- slide-12, etc.
-
- options.preventFragmentScroll
- When deep linking to a hash of a nested slide, this scrolls the deck
- container to the top, undoing the natural browser behavior of scrolling
- to the document fragment on load.
-
- options.setAriaHiddens
- When set to true, deck.js will set aria hidden attributes for slides
- that do not appear onscreen according to a typical heirarchical
- deck structure. You may want to turn this off if you are using a theme
- where slides besides the current slide are visible on screen and should
- be accessible to screenreaders.
