Today we will learn how to design a checkout form by combining HTML, CSS, Javascript and Bootstrap.
Forms of Payment
Checkout Form is an important and indispensable part of today's online business stores. As this is the final step where the customer pays to buy your product. Therefore, in building a payment form, we need to pay attention to parts such as providing detailed information, images, prices, and shipping costs for the product that the customer has selected. When you do the payment, you should attention to some features that must be so that users can easily update the quantity, change the color or delete the product. This helps users reduce unnecessary navigation as well as not leaving the page where you want customers to stay the most. Normally, when designing this section, we will need to pay attention to some of the following factors:
- Product photo.
- Product name and price
- The ability to remove products, change the product size details that the user has selected.
- Show total product price and shipping cost.
- The estimated delivery date can be checked
