HTML代码显示异常：编写文本与网页展示不符的修复求助

Hey Bob, let’s break down what’s going wrong and how to fix it—those weird characters like ’ and missing heading are totally fixable!

Why You’re Seeing Garbled Text #

Those messed-up characters are caused by mismatched character encoding. The special characters in your text (like the apostrophe ’) are Unicode characters, but your browser is trying to parse them with the wrong encoding (usually ISO-8859-1 instead of UTF-8). That’s why you get gibberish instead of your intended text.

Step-by-Step Fixes #

1. Add UTF-8 Encoding Declaration to Your HTML #

Put this meta tag at the very top of your <head> section—this tells your browser exactly which encoding to use for parsing the page:

<head>
  <meta charset="UTF-8">
  <!-- Rest of your head content (title, styles, etc.) goes here -->
</head>

This is the most critical step to fix the character garbling.

2. Ensure Your File is Saved in UTF-8 #

Open your HTML file in a code editor (like VS Code, Sublime Text, or Atom) and check the encoding:

• In VS Code: Look at the bottom-right corner of the window—you’ll see the current encoding. Click it, select "Save with Encoding", then choose "UTF-8".
• Other editors have similar options in their "File" or "Encoding" menus.

3. Fix the Missing Heading #

You mentioned your <h1 class="title2"> text isn’t showing up. Double-check your CSS for rules targeting .title2—it might be hidden accidentally:

• Look for styles like display: none or visibility: hidden on the .title2 class.
• Make sure there isn’t a more specific CSS selector overriding your heading’s visibility (e.g., body h1.title2 { display: none; }).

4. Clean Up Existing Garbled Text #

If some text is already messed up, replace the gibberish (like ’) with the original correct characters (like ’), then re-save the file with UTF-8 encoding.

Final Check #

After making these changes, refresh your browser—your text should display as intended, and your heading should show up if the CSS was the issue.
