[Name] auto-height [Type] integer or ratio [Default Value] 0 [Description] 
This option determines whether or not Cycle2 will provide height management for the slideshow which can be very useful in fluid or responsive designs. There are three ways this option can be used: an integer can be provided to identify the zero-based slide index for a sentinel slide the string "calc" can be provided to instruct Cycle2 to calculate the tallest slide and use it as the sentinel a ratio string can be provided which identifies the width:height aspect ratio for the container By default, the slideshow's first slide is used as the sentinel slide and its demensions will control the height of the slideshow container if the container does not have a specific height set via CSS. To force the slideshow container to a specific aspect ratio, for example to hold a set of images that are 600x400, use a ratio string like this: data-cycle-auto-height="600:400" To disable height management, set this option's value to -1 or false. See Auto Height demo for more info.
