Slider isn't showing at the right size on other devices
If the issue you're having is that the slider is clipping the images or showing too much white space, it's because the images themselves aren't optimized for being viewed through a slider. You have to account for the "responsiveness" of the slider by either re-sizing the images or toggling a few settings.
Here are some options;
1. Fix the height of the slider so that it is smaller. To do this, click the slider >>> edit >>> more >>> change the height accordingly.
2. Change it so that the image doesn't fill the slider (which causes it to enlarge). To fix this, click the slider >>> edit >>> design >>> images fill slider (off)
3. If all the images are different sizes, edit the images so that they all have the same (or similar) ratios. A good "all around" ratio for a slider is around 4:3 pixels, although this can vary widely depending on the look you're trying to achieve.
4. Use the hide on device feature. Create two-three separate sliders, one for each device, then use the "hide on device" feature to show each one separately.
