Size Considerations and Recommendations

By default, maintainAspectRatio is true, which means height is controlled through proportion.

If you want to have an image slider with constant height (regardless of width), you must set maintainAspectRatio to false.

By default, slideHeight is set to 100%, which will not work if the parent element height isn't defined (i.e. relative heights do not work if the parent height is auto). In that case you can use a fixed CSS unit for slideHeight. You can use any valid css height string like 100px or 25vh.

Play around with the demo here to see how you can use this image slider with or without explicit parent height.

With parent elements that have height:auto

• use proportion if you want an image slider that resizes responsively (this is the default configuration).
• use maintainAspectRatio="false" and a non-percentage slideHeight if you want a fixed height image slider.
• DO NOT use relative (%) values for slideHeight; the image slider will not render.

With parent elements that have a set height

• use maintainAspectRatio="false" if you want a fixed height image slider that fills the parent element (slideHeight is 100% by default).
• DO NOT use maintainAspectRatio="false" and slideHeight (unless slideHeight="100%"); the image slider will not
