Hello Adil,

Thank you for getting in touch with us!

You should create separate layouts for sliders on desktop and on mobile, you can do it two ways.
Since version 6 of LayerSlider you have the option to display layers only on certain devices (desktop, mobile, tablet). This feature is called device specific layers, and it gives you the option to create separate layers for mobile, tablet and desktop view in the same slide, and only show them on the required device. This only changes the slider on the layer level.

Additionally to the device specific layers, you could also build two sliders with different sizes or with different content/layout for desktop and mobile, include them both to the site, and only display them (using the Hide over and Hide under options in the Slider Settings) on the required device. You can change every slider option this way. So this gives you more control, but requires more work.
