Why is the slider preview different from the actual slider in the theme editor?

Every theme in Shopify has their own custom design and styles.

These things include:

FoxSell doesn't show the preview based on your theme's assets. We use a single set of assets to show the preview.

The purpose of the preview is to give an idea of the placement and color schemes of the FoxSell Sliders.

Any decisions on the section should be made only by seeing the final preview in the theme editor.
