Import Template File into Blogger Theme Safely

Import a Template File into Blogger/blogspot

Theme - Customize right-side dropdown menu - Revert

Select the .xml file

* I have prepared a test file that contains all the widgets, and none of the widgets use the h2 tag

View the Actual Template File Used by Blogger/blogspot

Theme - Customize right-side dropdown menu - Edit HTML

Note the Key Changes

Conclusion

When Blogger/blogspot imports a template file, the system forcibly sets the title within the Followers widget to h2

If you want to fully plan a template with h1, h2, ... tags, then do not use the Followers widget

Postscript

I myself know almost nothing about Blogger/blogspot template files; this knowledge comes entirely from various AI models.

The test file mentioned in this article was also created by AI.

Experts are welcome to point out my mistakes. ^_^
