If you want to create a new style for the checkout_success.php page, you can create a custom template of your choice and upload it to the themes//checkout/checkout_success.tpl. If the checkout folder is not present you can create a folder with name checkout.

If you want to add some custom/local changes in checkout_success.php, you need to add a custom php file with name custom_tpl_checkout_success.php in themes/functions/ folder where you can add the new changes and define those to a template variable. Also you should place that variable in themes//checkout/checkout_success.tpl.

We have a custom file custom_add.php in themes/functions/ folder which will be available for all files. If you want a new template variable for all the checkout section, you can define that on custom_add.php.
