Blank Pages in HTML Documents: How to Fix

When creating HTML web pages, you may encounter blank page issues . This can happen for a number of reasons, which this article will explore and provide ways to fix the problem.

Causes of blank page

Missing root element: Every HTML document must have a root element, usually <html> element. Without a root element, the browser cannot render the page.
Missing title element: The title element (<title>) is the text displayed in the browser window. If the title element is missing, the page may appear blank.
Syntax errors: Syntax errors prevent the browser from correctly parsing the HTML code.
Unable to load resource: Failure to load external resources (such as CSS files or images) may cause the page to appear blank.
Browser cache issues: Sometimes, browser cache prevents new versions of pages from loading.

Solution

1. Add the root element

Make sure your HTML document contains the following code:

<!DOCTYPE html>
<html>
  ...
</html>

Copy after login

2. Add the title element

Add the following code in the <head> element:

<head>
  <title>我的网页</title>
  ...
</head>

Copy after login

3. Check for syntax errors

Use HTML validator to find and fix syntax errors.

4. Check external resources

Make sure the CSS files and images used can be loaded normally.

5. Refresh the browser cache

Hold down the following key combination to refresh the browser cache:

Windows: Ctrl F5
Mac: Command Option R

Practical case

Suppose you have an HTML document named index.html , and it shows blank. Upon inspection, you find that the root and title elements are missing. After adding the following code, the problem was solved:

<!DOCTYPE html>
<html>
  <head>
    <title>我的网页</title>
  </head>
  <body>
    ...
  </body>
