  <p>Hello friends, How can I prevent the border from appearing when the welcome screen appears?
  That means I want to see a border on the only main page. How can fix this on my code? I couldn't block the border during the welcome screen. I also added a picture of the desired situation. You can see it below. I am waiting for your help.
