<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>
| 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:
