    <!DOCTYPE html>
<html>
<head>
  <title>Example</title>
</head>
<body>

Example html doc......

</body>
</html>

    Hi there PunitJain,

    your basic HTML document should look like this...
    


<!DOCTYPE HTML>
<html lang="en">
<head>

<meta charset="utf-8">
<meta name="viewport" content="width=device-width,height=device-height,initial-scale=1">

<title>Untitled document</title>

<link rel="stylesheet" href="screen.css" media="screen">

</head>
<body>
   
</body>
</html>
    Code (markup):
    ...PERIOD !

    Doesn't really help, the poor sod has been suckered into using the shit-show that is "cheerio" which is why stuff like that is (poorly) auto-generated for him. "cheerio.js" is the poster child for SPA only "f*** accessibility" asshat nonsense. A how-to guide on "screw usability and accessibility" hiding behind bald faced lies of making things "better" or "easier". Of course it's based on the shit-show that is jQuery.

    He'd be doing something like:
    
const cheerio = require('cheerio');
$.html();
    Code (markup):
    And it spits out the HTML/HEAD/BODY tags and the contents therein for him.

    Because it's jQuery f***wittery, I believe you can selector the page and simply replace its content.

    $("head").html("<title>Test</title>");

    Would replace the entire contents of the head with that title tag.

    Horrifying waste of bandwidth though, possibly insecure since $().html() is a innerHTML wrapper. But that's to be expected with the shit-show of developer ignorance, incompetence, and ineptitude that is jQuery. Worst of all it's doing something client side that generally has ZERO honking business being even touched client-side.

    I think that's something that pisses off jQ fans when I rag on it. I do know how to use it, so I know where to stick the knife and twist. And knowing it and how it works is why I hate it and cannot fathom how or why anyone is gullible enough to use it by choice.

    But to be fair I say the same about all the hot and trendy framework bullshit. Makes you work harder, not smarter.
