GitHub.io新作品集页面CSS及图片无法加载问题求助

Hey there! Let’s work through this frustrating problem with your updated portfolio page—CSS and images failing to load even after clearing cache is a common roadblock, but we can narrow it down step by step:

1. Verify Resource Paths Are Correct #

• First, double-check the relative/absolute paths in your HTML for CSS and images. GitHub Pages serves your site from the root of your repository, so paths like ./css/style.css or /css/style.css should work (avoid local absolute paths like C:/Projects/...).
• Open your browser’s DevTools (F12), go to the Network tab, and refresh the page. Look for resources marked with a 404 error—this tells you the path being requested is incorrect.

2. Check GitHub Pages Deployment Status #

• Head to your repository’s Actions tab to confirm the latest deployment workflow completed successfully. If it failed, click into the run to view error logs (common issues include missing dependencies or build errors).
• Also, check Settings > Pages to ensure you’re deploying the correct branch (e.g., main) and root folder—accidentally switching branches can break resource loading entirely.

3. Watch Out for Case Sensitivity #

• GitHub is case-sensitive! If your local files use Style.css but the repo has style.css, your browser will load it locally but GitHub Pages will return a 404. Make sure filenames and folder names match exactly between your local setup and the repository.

4. Force a Hard Browser Refresh #

• A regular cache clear might not cut it—try a hard refresh to bypass all cached resources:
  • Windows/Linux: Ctrl + Shift + R
  • Mac: Cmd + Shift + R
• This forces the browser to pull everything fresh from the GitHub Pages server.

5. Bypass CDN Caching #

• GitHub Pages uses a CDN, which can cache old versions of your site even after you deploy updates. Try:
  • Waiting 10-15 minutes for the CDN to propagate your new changes.
  • Adding a version parameter to your resource links (e.g., <link rel="stylesheet" href="/css/style.css?v=2">)—this tricks the browser into treating it as a new, uncached resource.

6. Ensure Resources Aren’t Ignored by .gitignore #

• Check your repository’s .gitignore file to make sure you didn’t accidentally exclude CSS folders, image directories, or specific files. Navigate to the repo on GitHub to confirm the relevant folders exist and contain your updated resources.
