You can apply a saved skin to change the look of your shopping cart storefront, including the settings for template, color theme, custom colors and fonts, category page style, product page style, and any advanced CSS you've included.
When you apply a saved skin, your current storefront settings are overwritten. To prevent permanently losing your current settings, back them up as a new skin before you apply a saved skin.
You must publish the Website before the new skin's settings are applied to your current storefront design.
