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