Code was working on 7.0 and it doesn't on 7.1 - Can i get an update? Thanks

Hello, that's added in the advanced > custom code setting popup on a page working good on 7.0 , but when i switched over to 7.1 it stopped working, can you tell me what's wrong thanks. 

Here is the code: 

 

<style>
  /* Hide blocks outside of edit mode */
  body:not(.sqs-edit-mode) .sqs-layout .sqs-block {
    pointer-events: none;
    opacity: 0;
    visibility: hidden;
  }

  /* Show specific blocks when condition is met */
  body:not(.sqs-edit-mode) .removex {
    pointer-events: auto !important;
    opacity: 1 !important;
    visibility: visible !important;
  }

  /* Lock and fade out certain elements */
  body:not(.sqs-edit-mode) .subslock {
    opacity: 0 !important;
    pointer-events: none;
  }

  body:not(.sqs-edit-mode) .fadeload {
    opacity: 1 !important;
  }

  body:not(.sqs-edit-mode) .sqs-layout {
    opacity: 0;
    transition: opacity 1ms ease-in-out;
  }

  /* Responsive font size for header */
  @media screen and (max-width: 768px) {
    .subsmessage h1 {
      font-size: 1.5rem;
    }
  }

  @media screen and (min-width: 769px) {
    .subsmessage h1 {
      font-size: 2rem;
    }
  }

  /* Button styling */
  .subs-button {
    border: none;
    padding: 15px 32px;
    text-align: center;
    text-decoration: none;
    display: inline-block;
    font-size: 16px;
    margin: 4px 2px;
    cursor: pointer;
  }

  .subs-button.join-now {
    background-color: hsl(19, 87%, 53%);
    color: white;
  }

  .subs-button.member-login {
    background-color: white;
    color: black;
    border: 1px solid black;
  }

  /* Responsive button adjustments */
  @media screen and (max-width: 768px) {
    .subs-button {
      font-size: 12px;
      padding: 10px 20px;
    }
  }
