textarea占位符无法正常显示求助：退格两次才显现

Hey there! I spotted the issue right away—your HTML has some syntax errors that are throwing off how browsers parse the textarea element, which is why the placeholder is behaving so strangely. Let's break down the problems and fix them:

The Issues in Your Code: #

• Malformed style attribute: You have align-top: " in your style declaration—this is invalid CSS (there's no align-top property, and you left an unclosed quote hanging). This messes up the browser's ability to read the rest of the element's attributes correctly.
• Misplaced name attribute: The name attribute is stuck inside the style attribute's code, which makes the browser misinterpret it and the other properties.
• Inconsistent quoting: While not a critical error, it's best practice to wrap all attribute values in consistent quotes (double quotes here) to avoid parsing confusion.

Corrected Code: #

<div class="form-group">
  <label>Description:</label>
  <textarea 
    placeholder="Describe yourself" 
    style="height:200px; width:300px; font-size:12pt;"
    name="profile_description" 
    class="form-control" 
    required
  ></textarea>
</div>

What Changed: #

1. Removed the invalid align-top: " part from the style attribute (if you meant to adjust vertical alignment, use vertical-align: top; instead, but only if your layout actually needs it).
2. Moved the name attribute outside the style declaration so it's properly recognized by the browser.
3. Cleaned up the quoting around all attribute values to be consistent and valid.
4. Ensured all style properties are properly separated with semicolons.

Once you update your code to this version, the placeholder should show up immediately in all browsers without needing to press backspace at all.
