HTML Elements

HTML elements are written with a start tag, with an end tag, with the content in between:

<tag>content</tag>

The HTML element is everything from the start tag to the end tag:

<p>My first HTML paragraph.</p>

Start tag	Element content	End tag
<h1>	My First Heading	</h1>
<p>	My first paragraph.	</p>
<br>

	Some HTML elements do not have an end tag.

Nested HTML Elements

HTML elements can be nested (elements can contain elements).
All HTML documents consist of nested HTML elements.
This example contains 4 HTML elements:

Example

<!DOCTYPE html>
< html>
<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

< /body>
</html>

HTML Example Explained

The <html> element defines the whole document.
It has a start tag <html> and an end tag </html>.
The element content is another HTML element (the <body> element).

<html>
< body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

< /body>
< /html>

The <body> element defines the document body.
It has a start tag <body> and an end tag </body>.
The element content is two other HTML elements (<h1> and <p>).

<body>

<h1>My First Heading</h1>
<p>My first paragraph.</p>

< /body>

The <h1> element defines a heading.
It has a start tag <h1> and an end tag </h1>.
The element content is: My First Heading.

<h1>My First Heading</h1>

The <p> element defines a paragraph.
It has a start tag <p> and an end tag </p>.
The element content is: My first paragraph.

<p>My first paragraph.</p>

Don't Forget the End Tag

Some HTML elements will display correctly, even if you forget the end tag:

Example

<html>
<body>

<p>This is a paragraph
<p>This is a paragraph

</body>
</html>

The example above works in all browsers, because the closing tag is considered optional.
Never rely on this. It might produce unexpected results and/or errors if you forget the end tag.

Empty HTML Elements

HTML elements with no content are called empty elements.
<br> is an empty element without a closing tag (the <br> tag defines a line break).
Empty elements can be "closed" in the opening tag like this: <br />.
HTML5 does not require empty elements to be closed. But if you want stricter validation, or you need to make your document readable by XML parsers, you should close all HTML elements.

HTML Tip: Use Lowercase Tags

HTML tags are not case sensitive: <P> means the same as <p>.
The HTML5 standard does not require lowercase tags, but We recommends lowercase in HTML4, and demands lowercase for stricter document types like XHTML.

HTML Basic Examples

Don't worry if these examples use tags you have not learned.

You will learn about them in the next chapters.

HTML Documents

All HTML documents must start with a type declaration: <!DOCTYPE html>.
The HTML document itself begins with <html> and ends with </html>.
The visible part of the HTML document is between <body> and </body>.

Example

<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>

<p>My first paragraph.</p>

</body>
</html>

HTML Headings

HTML headings are defined with the <h1> to <h6> tags:

Example

<h1>This is a heading</h1>
< h2>This is a heading</h2>
< h3>This is a heading</h3>

<!DOCTYPE html>

<html>

<body>

<h1>This is heading 1</h1>

<h2>This is heading 2</h2>

<h3>This is heading 3</h3>

<h4>This is heading 4</h4>

<h5>This is heading 5</h5>

<h6>This is heading 6</h6>

</body>

</html>

HTML Paragraphs

HTML paragraphs are defined with the <p> tag:

Example

<p>This is a paragraph.</p>
< p>This is another paragraph.</p>

<!DOCTYPE html>

<html>

<body>

<p>This is a paragraph.</p>

</body>

</html>

HTML Links

HTML links are defined with the <a> tag:

Example

<!DOCTYPE html>

<html>

<body>

</body>

</html>

The link's destination is specified in the href attribute.
Attributes are used to provide additional information about HTML elements.

HTML Images

HTML images are defined with the <img> tag.
The source file (src), alternative text (alt), and size (width and height) are provided as attributes:

Example

<!DOCTYPE html>

<html>

<body>

</body>

</html>

basic structure of a HTML coding.

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

<h1>my first code</h1>
<p>My first page.</p>

</body>
</html>

The DOCTYPE declaration defines the document type to be HTML
The text between <html> and </html> describes an HTML document
The text between <head> and </head> provides information about the document
The text between <title> and </title> provides a title for the document
The text between <body> and </body> describes the visible page content
The text between <h1> and </h1> describes a heading
The text between <p> and </p> describes a paragraph

What is a HTML tag?

HTML tags are keywords (tag names) surrounded by angle brackets:

<tag>content</tag> 

HTML tags normally come in pairs like <p> and </p>
The first tag in a pair is the start tag, the second tag is the end tag.
The end tag is written like the start tag, but with a slash before the tag name .

HTML Page Structure

Below is 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>

	Only the <body> area (the white area) is displayed by the browser.
