Dear @MinhajAhmed106 ,

I have reviewed your requirement, you just need to edit css script and the issue will be resolved. You can follow my instructions!

Step 1: Go to Admin → Online store → Theme > Edit code:

Step 2: Search for the file base.css. And add this code snippet to the end of the file.

.checkout .main-header__logo {
    margin-bottom: 10px !important; 
}

.checkout .main-header__nav {
    margin-top: 10px !important; 
}

In this step, you can change value of margin-bottom of logo and margin-top of nav to reduce spacing between they.

Step 3: Save your code and reload this page.

If it not work, Can you kindly share your store link (with the password, if any) with us? We will check it and suggest you a solution if possible.

I hope these instructions will help you. If they are helpful, please give us likes and mark as the solution.

Have a nice day sir!

Hi @MinhajAhmed106 ,

Sorry about misunderstanding your require.

About this your issue, the cause lies in the customizations being made on the Shopify checkout page.
Shopify does not allow editing, embedding, or interfering with the checkout page due to user information security reasons.
The CSS properties are contained in a compressed file managed by Shopify with their CDN. The class names are also different from usual so cannot be changed style in file css or theme.liquid on our theme.

Sorry for not being able to help you. I will leave a comment here to wait for other solutions from everyone to solve this problem.

Good luck, and have a nice day sir!
