How to Set Style to Title Tag in Header

Can we set style to title tag in header

You can apply CSS to the <title> element, but not though the style attribute (since it is for "All elements but BASE, BASEFONT, HEAD, HTML, META, PARAM, SCRIPT, STYLE, TITLE").

I'm not aware of any browser that will apply CSS for the rendering of the title in browser tabs or title bars though.

You can, however, do something like:

head { display: block; }
title { display: block; font-size: 200%; font-weight: bold; }

styling title tag in the head with css or js

The browser allows JS to give the page dynamic behaviour, but changing the font of a window belongs to the OS.
The tab, instead is controlled by the browser but it doesn't interact with the page.

How to apply style to the HTML title element?

No, there is no way set a style to this element, as it is controlled by the browser and the user. The only thing you can do to the title while viewing the page, is change it, but stay on the same page:

function changeTitle() {  document.title = "Title Changed!";  document.getElementById('test').innerHTML = "Title has been changed!";}

<button onclick="changeTitle()">Click Me!</button>
<p id="test"></p>
<p>View source to see the effect!</p>

How do you change the style of the Title tag in css?

You don't. The title tag is not formatted text. If JavaScript is an option you can use: document.title = document.title.toUpperCase();

Display superscript in title tag of html head

Try this:

<title>🅪 or 🅪 or lt;/title>

Or:

document.title = "🅪 or 🅪 or quot;;

Alternative is:

document.title = '\uD83C\uDD6A';

If none of these are visible, it's probably a font issue on the browser itself. Utf-8 is widely supported.

EDIT

Ensure you are setting your charset:

<meta http-equiv="Content-type" content="text/html; charset=utf-8" />

The UTF-8 character set supports all languages. But just in case..

Add a language to your html:

<html lang="en">

All language codes can be found here.

Will update when I find more information on this matter...

In the end, formatting the title tag is a time consuming activity.

Is the MC character really important? Does it add anything valuable to the SERP (Search Engine Results Page)?

MC in superscript is used as a trademark sign in, for example, Quebec, Canada.
In Canada, there is no legal obligation to use the ® , TM, MC or MD
symbols. It is however recommend to use ® (registered trade-mark) or
MD (marque de commerce déposée) in association with your registered
trade-marks. Symbols TM (trade-mark) or MC (marque de commerce) can be
used in association with your other trade-marks whether an application
has been filed or not. These symbols remind consumers and your
competitors that you are the owner of the trade-marks in question.

A title or a header for a div

What you want looks like a fieldset element with a legend tag inside, but I wouldn't recommend using them.
Just use position: absolute like this:

<div class='section'>
    <header>Header</header>
    ....
</div>

.section{
    position: relative;
}

.section header{
    position: absolute;
    top: 0;
    transform: translate(0, -50%);
    background: white;
}

Can I give a title tag a color and different font?

Answer is NO you cannot do that in any way....you cannot apply any styles to page title, btw you can just blink the titles

Blinking Titles

More Info On CSS Which You Are Using:

If you are declaring something like this

title{ color: red; font: 12px tahoma;}

You don't need to define any class as you are targeting specific title tag which is only 1 in your whole document

And if you are using .title than your CSS should be

.title{ color: red; font: 12px tahoma;}
