Hello

1. By default the images of your slideshow have a background-size property set to 'cover'. This ensures that the slideshow will automatically fill the area provided regardless of the screensize. Because of this your images will be cropped either vertically or horizontally depending on the device. Changing this property will cause a 'letterbox' effect on your slideshow with blank space appearing either horizontally or vertically.

2. Examples of classes that can be used in the animate on scroll option can be found here... http://demo.joomla51.com/0124/index.php/features/animations-on-scroll

Thank you Ciaran,
I will do some experimenting with size to try and get the effect I want.
Just to clarify, we are talking about the "header" option in the template styling area and not the separate J51 Slideshow module (which I have turned off), right? (vegas-slide). Is there a way to change the height of this showcase module?

Thanks again.

Yes that is correct.

You can set a specific height to your vegas slideshow by adding the following to the Custom CSS field of your templates parameters (edit to taste)...

#header_bg {

    height: 700px !important;

}
