New points:
1) Mobile version – Add to cart and Buy now – space issue for mobile version only.
check the drive link for a screenshot – 1
2) Button issue – on clicking buttons of view cart, proceed to checkout and place order after clicking the section is going blank – check the screenshot – 2
3) Validation error – Can we do the validation error just below the form fields? Screenshot – 3
4) on clicking Add to cart button, can we directly open the popup of the cart right side tab? Currently, after clicking on add to cart – we need to go and click on the cart icon to open the popup. That must be automatically done.
