<!DOCTYPE html>
<html>
<head>
  <title>A Meaningful Page Title</title>
</head>
<body>

The content of the document......

</body>
</html>
A Meaningful Page Title

The content of the body element is displayed in the browser window.

The content of the title element is displayed in the browser tab, in favorites and in search-engine results.

<style>
  body {background-color: powderblue;}
  h1 {color: red;}
  p {color: blue;}
</style>

The HTML <link Element>

The <link> element defines the relationship between the current document and an external resource.

<link rel="stylesheet" href="mystyle.css">

The HTML <meta> Element

The <meta> element is typically used to determine the character set, page description, watchwords, author of the document, and viewport settings.

The metadata won’t be shown on the page, however are used by browsers (how to show content or reload page), via web search engines (watchwords), and other web services.

Examples

Define the character set used:

<meta charset="UTF-8">

Define keywords for search engines:

<meta name="keywords" content="HTML, CSS, JavaScript">

Define a description of your web page:

<meta name="description" content="Free Web tutorials">

Define the author of a page:

<meta name="author" content="Salman Khan">

Refresh document every 30 seconds:

<meta http-equiv="refresh" content="30">

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Example of <meta> tags:

Example

<meta charset="UTF-8">
<meta name="description" content="Free Web tutorials">
<meta name="keywords" content="HTML, CSS, JavaScript">
<meta name="author" content="Salman Khan">

Setting The Viewport

The viewport is the user’s apparent area of a site page. It varies with the gadget – it will be smaller on a cell phone than on a computer screen.

You ought to incorporate the accompanying <meta> element in the entirety of your website pages:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

This gives the browser directions on how to control the page’s measurements and scaling.

The width=device-width part sets the width of the page to follow the screen-width of the gadget (which will vary depending on the device).

The initial-scale=1.0 part sets the initial zoom level when the page is first loaded by the browser.

Here is an illustration of a site page without the viewport meta tag, and a similar website page with the viewport meta tag:


The HTML <script> Element

The <script> element is used to define client-side JavaScripts.

The accompanying JavaScript states “Hi JavaScript!” into an HTML element with id=”demo”:

Example

<script>
function myFunction() {
  document.getElementById("demo").innerHTML = "Hello JavaScript!";
}
</script>
Page Title
