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:
<tagname> Content goes here... </tagname>
The HTML element is everything from the start tag to the end tag:
<h1>My First Heading</h1><p>My first paragraph.</p>
Note: Some HTML elements have no content (like the <br> element). These elements are called empty elements. Empty elements do not have an end tag!
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:
HTML Page Structure
Below is a visualization of an HTML page structure:
<html><head><title>Page title</title></head><body><h1>This is a heading</h1><p>This is a paragraph.</p><p>This is another paragraph.</p></body></html>
Note: The content inside the <body> section 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.
