Hi guys, can someone tell me how can I change the entiry checkout page like this:
So after you press checkout it show everything , you can add in one page everything details and card details and its done. On normal shopify you need to add your details , then shipping , then credit card....
That's not a Shopify checkout page. They are using Crossboarder Checkout by FedEx nee Bongo Checkout. The checkout is external to Shopify and loaded inside an Iframe. Shopify's checkout can only be customized if you're on a Plus plan and have requested / been granted permission to customize checkout.liquid.
Nick here from Shopify.
Karl is exactly right here. To be able to customize the checkout in any way you would need to be on the Shopify Plus plan. You can find out more details about this and the checkout.liquid file from information document Shopify has on it here.
In saying this above, you can make some edits to the checkout page such as adding your logo, background images, colors or text fonts to give the checkout it's unique identity. You can see the guide Shopify has on how to implement these edits here should you wish.
Hope this helps and answers your question.
All the best, Nick
