  • Preview your design on both desktop and mobile devices before publishing.

Well-balanced shadows improve visual hierarchy while keeping your interface clean and modern.

Common Mistakes to Avoid

Although box shadows are simple to apply, overusing them can make a website look cluttered.

  • Applying different shadow styles on every page.
  • Using heavy shadows on small elements.
