A Simple HTML Document
Example
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
Example Explained
- The
<!DOCTYPE html>
declaration defines that this document is an HTML5 document - The
<html>
element is the root element of an HTML page - The
<head>
element contains meta information about the HTML page - The
<title>
element specifies a title for the HTML page (which is shown in the browser's title bar or in the page's tab) - The
<body>
element defines the document's body, and is a container for all the visible contents, such as headings, paragraphs, images, hyperlinks, tables, lists, etc. - The
<h1>
element defines a large heading - The
<p>
element defines a paragraph
What is an HTML Element?
An HTML element is defined by a start tag, some content, and an end tag:
The HTML element is everything from the start tag to the end tag:
Start tag | Element content | End tag |
---|---|---|
<h1> | My First Heading | </h1> |
<p> | My first paragraph. | </p> |
<br> | none | none |
Web Browsers
The purpose of a web browser (Chrome, Edge, Firefox, Safari) is to read HTML documents and display them correctly.
A browser does not display the HTML tags, but uses them to determine how to display the document:
Note: The content inside the <body> section (the white area above) will be displayed in a browser. The content inside the <title> element will be shown in the browser's title bar or in the page's tab.
