自定义CSS/HTML/JS烟雾动画不可见问题求助

Hey there, let's break this down step by step—you've got the full FTP files, so we can track down that smoke animation without the original developer's notes. Here's what I'd do to get it working on your new site:

• Locate the animation-related files
  Start by digging through the FTP folders to find assets tied to the smoke effect:

  • Look for .js, .css, or image/sprite files with names like smoke.js, animation.css, or smoke-sprite.png. Common spots are /js, /assets, /dist, or even the root directory for smaller sites.
  • Open the old site's main HTML files (like index.html or the specific page where the smoke appeared) and scan for script tags or CSS links that reference these files—these will be your key clues.

• Figure out how the animation is initialized
  Once you've found the relevant files:

  • For JS/jQuery-driven animations: Open the JS file and look for initialization functions (e.g., initSmokeAnimation()) or event listeners like $(document).ready(function() { ... }) that kick off the smoke effect. Note any target elements (like a div with id="smoke-container") that the code references.
  • For CSS-only animations (less common for complex smoke, but possible): Check CSS files for @keyframes rules with smoke-related names, or classes that apply animation properties (e.g., .smoke-effect { animation: smoke-float 10s infinite; }).

• Test the animation in isolation
  Create a simple test HTML file to verify the animation works on its own:

  <!DOCTYPE html>
  <html>
  <head>
    <link rel="stylesheet" href="path/to/smoke-styles.css">
    <!-- Include jQuery if the animation uses it (match the old site's version!) -->
    <script src="path/to/jquery.min.js"></script>
    <script src="path/to/smoke-animation.js"></script>
  </head>
  <body>
    <!-- Add the target element the animation needs -->
    <div id="smoke-container"></div>
  </body>
  </html>
  

  This helps rule out conflicts with other code from the old or new site.

• Fix common issues
  If the animation doesn't run in your test file:

  • Open your browser's dev tools (F12) and check the Console tab for errors—missing image assets, undefined variables, or missing jQuery are the most frequent problems.
  • Double-check that all file paths are correct (relative paths might need updating if your new site's folder structure differs from the old one).
  • Ensure the target element (like #smoke-container) exists in your HTML and matches the selector used in the animation code.

• Integrate into your new site
  Once the animation works in isolation:

  • Copy the necessary files (JS, CSS, images) into your new site's asset folders.
  • Link the files in your new site's HTML, updating paths as needed.
  • Add the required target element to the page where the smoke should appear.
  • Test again and use the browser console to debug any new conflicts with your existing site code.
