Html Elements
An HTML element is declared by a start tag, some content, and an end tag.
The HTML element is everything from the start tag to the end tag:<tagname>Content goes here…</tagname>
Example:
My First Heading
My first paragraph.
My First Heading
My first p
Output:
My First Heading
My first paragraph.
My First Heading
My first p
Nested HTML Elements
HTML elements can be nested which means that the elements can contain other elements. All HTML documents have nested HTML elements.
The following example contains four HTML elements (<html>, <body>, <h1> and <p>)
Example
My First Heading
My first paragraph.
Output:
My First Heading
My first paragraph.
Example Explained:
- The <html> element is the root element that defines the whole HTML document.
- It consists of a start tag <html> and an end tag </html>.
- Within the <html> element there is a <body> element.
- The <body> element defines the document’s body.
- It has a start tag <body> and an end tag </body>.
- Then, within the <body> element there are two other elements: <h1> and <p>
The <h1> element defines a heading.
It has a start tag <h1> and an end tag </h1>:
The <p> element describes a paragraph.
It consist of a start tag <p> and an end tag </p>
Never skip The End Tag
Some of the HTML elements are displayed correctly, even if you forget the end tag:
Example
This is a paragraph.
This is a paragraph.
Empty HTML Elements
HTML elements consist of no content and are called empty elements.
The <br> tag defines a line break, and is an empty element without a closing tag:
Example
This is a
paragraph with a line break.
Output:
This is a
paragraph with a line break.
