HTML Tag Attributes
HTML tags can have attributes. Attributes provide additional information to an HTML element.
Attributes always come in name/value pairs like this: name="value".
Attributes are always specified in the start tag of an HTML element.
Attributes Example 1:
<h1> defines the start of a heading.
<h1 align="center"> has additional information about the alignment.
Attributes Example 2:
<body> defines the body of an HTML document.
<body bgcolor="yellow"> has additional information about the background color.
Attributes Example 3:
<table> defines an HTML table. (You will learn more about HTML tables later)
<table border="1"> has additional information about the border around the table.
Use Lowercase Attributes
Attributes and attribute values are case-insensitive. However, the World Wide Web Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4 recommendation, and XHTML demands lowercase attributes/attribute values.
