I have created (bought and edited) an HTML responsive email template for customer account registration notifications.
I used it for modifications visual studio and tested it in local browser. The page renders beautifully without any issues.
When I copy and paste the same source code into the body of the message template editor, the CSS layout shifts.
I tried moving the CSS styles into the body of the HTML page (from the head section), but even then the CSS layouts are changing around the area for the logo.
Also, I notice the javascript is not working on the rendered page and in fact, the javascript just disappears when we switch between the source code view and design view.
Please see the code below for reference:
