Language Attribute

To add a language attribute in Blogger, you should alter the HTML code of your blog. Here are the means you can follow:

1.         Go to your Blogger dashboard and select the blog you need to alter.

2.         Click on the "theme" tab and afterward click on the "Alter HTML" button.

3.         Search for the <html> label in the code and add the lang attribute to it. For example, if you need to set the language to English, you would add lang="en" to the <html> label like this: <html lang="en">

4.         Save the progressions to your layout.

Note: It's critical to take note that this will set the language for the whole blog, not only for a particular post or page:
