Checkout or order processing is a final stage of any marketing campaign or eCommerce website without any doubt. So I create modern design awesome checkout wizard using HTML, CSS and jQuery fully hand-coded. In this checkout wizard, you see when first step is completed than its close and up next is open as same follow with other steps. Or, suppose if you filled any wrong entry and submit those step than you again go to same step directly or those steps is already completed and have no mistake which shown as completed. So its user-friendly or easily to manage custom changes as per requirement at the developer ends.
