首页布局自动变更问题求助：内容两侧出现空白区域

Hey there, let's work through this homepage layout problem together—since only the homepage is showing those side gaps while other pages are fine, we can target our checks pretty specifically:

• Inspect homepage-specific styles first
  Open your browser's dev tools (F12 or right-click > "Inspect"), then look at the main content container on the homepage. Check for unexpected margin-left, margin-right, padding, or max-width values that might be squeezing the content. Compare this container's styles to the same element on a working page—you’ll often spot a missing class or a newly added style that’s causing the gap. Also keep an eye out for broken media queries (e.g., a responsive rule that’s incorrectly applying to all screen sizes instead of just mobile).

• Check for template or layout file changes
  If you’re using a CMS or framework, verify if the homepage’s template file was modified recently. It’s easy to accidentally remove a full-width container class, nest an extra restricted-width div, or alter the layout structure without noticing. If the homepage loads dynamic components (like a hero slider or featured content block), check if those components have updated styles that are overriding the page’s global layout.

• Clear cache and refresh
  Browser cache or CDN caching can sometimes serve outdated styles. Try a hard refresh (Ctrl+Shift+R on Windows, Cmd+Shift+R on Mac) to force the browser to load fresh resources. If you use a CDN, log in and clear the cache for the homepage specifically—old cached assets are a common culprit for sudden layout shifts.

• Test third-party scripts/plugins
  Have you added any new third-party tools (analytics, ads, widgets) to the homepage lately? These scripts can inject unexpected CSS that messes with your layout. Try temporarily disabling any homepage-specific plugins or scripts, then reload the page to see if the gaps disappear. If they do, you’ll know which tool is causing the issue and can adjust its styles or placement.

• Verify responsive breakpoints
  Double-check your homepage’s responsive styles. Sometimes a breakpoint that’s meant to adjust layout for small screens gets misconfigured, causing the restricted width to apply to desktop views too. Use the dev tools’ responsive view to test different screen sizes and see if the gaps appear or disappear at specific breakpoints.

Start with the dev tools inspection—it’s usually the quickest way to pinpoint the problem. Let me know what you uncover, and we can refine the fix further!
