HTML Elements
HTML documents are text files made up of HTML elements.
HTML elements are defined using HTML tags.
HTML Tags
- HTML tags are used to mark-up HTML elements
- HTML tags are surrounded by the two characters < and >
- The surrounding characters are called angle brackets
- HTML tags normally come in pairs like <b> and </b>
- The first tag in a pair is the start tag, the second tag is the end tag
- The text between the start and end tags is the element content
- HTML tags are not case sensitive, <b> means the same as <B>
HTML Elements
Remember the HTML example from the previous page:
HTML Code:
<html>
<head>
<title>Title of page</title>
</head>
<body>
This is my first homepage. <b>This text is bold</b>
</body>
</html>
This is an HTML element:
HTML Code:
<b>This text is bold</b>
The HTML element starts with a
start tag: <b>
The
content of the HTML element is: This text is bold
The HTML element ends with an
end tag: </b>
The purpose of the <b> tag is to define an HTML element that should be displayed as bold.
This is also an HTML element:
HTML Code:
<body>
This is my first homepage. <b>This text is bold</b>
</body>
This HTML element starts with the start tag <body>, and ends with the end tag </body>.
The purpose of the <body> tag is to define the HTML element that contains the body of the HTML document.
Why do We Use Lowercase Tags?
We have just said that HTML tags are not case sensitive: <B> means the same as <b>. If you surf the Web, you will notice that plenty of web sites use uppercase HTML tags in their source code. We always use lowercase tags. Why?
If you want to follow the latest web standards, you should always use lowercase tags. The World Wide Web Consortium (W3C) recommends lowercase tags in their HTML 4 recommendation, and XHTML (the next generation HTML) demands lowercase tags.
