Update index.html

Incorrect Comments: The comments in the HTML are not properly formatted. The use of multi-line comments within HTML can be confusing, especially if you're sharing the code with others. It's advisable to use single-line comments () for clarity.

Missing meta Tags: Although the viewport tag is included, the charset declaration is present but could benefit from additional meta tags for SEO, like a description or keywords.

Accessibility:

The label elements are associated with their corresponding input fields, but not all elements have for attributes that match their input IDs. Ensure all labels correctly reference their inputs.
Consider adding aria-label or aria-describedby attributes to improve accessibility for users relying on screen readers.
Inconsistent Input Types:

The expiration date fields are using elements, which is appropriate. However, there’s no placeholder for the selected month or year, which may confuse users. The CCV field could have an input type of text instead of number to allow for leading zeros (e.g., 012). Form Validation: While basic validation is performed in JavaScript, the HTML could benefit from using attributes like required, minlength, and maxlength to provide built-in HTML validation. Hard-coded Year Options: The expiration year dropdown only goes up to 2028. It would be better to dynamically generate these options or ensure that they are updated for future years. Card Number Format: The input field for the card number does not automatically format as the user types (e.g., grouping numbers in sets of four). This could enhance user experience. Missing DOCTYPE Declaration: The declaration is present, but ensure it is the very first line in the document to avoid rendering issues. No Fallback Content for SVG: While you have an SVG logo, consider including fallback content (like a PNG) for browsers that do not support SVG. HTML Structure: The heading for "Checkout" should ideally be wrapped in a or tag for better semantic structure. There is a missing closing tag for the main container of the card flip effect (though it seems to be implied). Missing autocomplete Attributes: Adding autocomplete attributes to input fields can enhance user experience by allowing browsers to pre-fill information. Inconsistent Use of Classes and IDs: While the class names are descriptive, ensure consistency in naming conventions (e.g., input-cart-number vs. input-expiration).
