About This HTML Issue
The http-equiv attribute on the <meta> element does not accept "title" as a valid value.
The http-equiv attribute is designed to simulate specific HTTP response headers. It only accepts a limited set of predefined values: content-type, default-style, refresh, x-ua-compatible, and content-security-policy. Using "title" is not among these valid values and will trigger a validation error.
If you want to set the title of your page, use the <title> element inside <head> instead. The <title> element is the correct and standard way to define the document's title, which appears in the browser tab and is used by search engines.
Bad Example
<head>
<meta http-equiv="title" content="My Page Title">
</head>
Good Example
<head>
<title>My Page Title</title>
</head>
