HTML elements is everything from the start tag to the end tag.
HTML have tow type of tags, one: start tag is often is called the opening tag, and second: end tag is often called the closing tag.
HTML Element tag:
HTML element starts with a start tag or opening tag and ends with an end tag or closing tag.
The element content is everything between the start and the end tag or opening / closing tag.
Some HTML elements have empty content.
Empty elements are closed in the start tag.
HTML Element Explained:
<p>My first HTML paragraph.</p>
The <p> element:
<p>This is my first HTML paragraph.</p>
The <p> element defines a paragraph in the HTML document.
The element has a start tag <p> and an end or closing tag </p>.
The element content is: This is my first HTML paragraph.
The <body> element:
<body>
<p>This is my first HTML paragraph.</p>
</body>
<body>
<p>This is my first HTML paragraph.</p>
</body>
The <body> element defines the body of the HTML document.
The element has a start tag <body> and an end or closing tag </body>.
The element content is another HTML element (a p element).
The <html> element:
<html>
<body>
<p>This is my first HTML paragraph.</p>
</body>
</html>
The <html> element defines the whole HTML document.
The element has a start tag <html> and an end or closing tag </html>.
The element content is another HTML element (the body element).
Don't Forget the End or Closing Tag:
Some HTML elements might display correctly even if you forget the end tag:
<p>This is a HTML paragraph
The example above works in most browsers, because the closing tag is considered optional.
Never rely on this. Many HTML elements will produce unexpected results and/or errors if you forget the end tag .
[Never forget use End or Closing Tag, must use End or Closing Tag.]
Empty HTML Elements:
HTML elements with no content it's called empty elements.
<br> and <hr/> is an empty element without a closing tag (the <br> tag defines a line break and <hr/> tag defines a line border).
Tip: In XHTML, all elements must be closed. Adding a slash inside the start tag, like <br />, is the proper way of closing empty elements in XHTML.
