XHTML Attributes
XHTML tags can have attributes.
Attribute values must always be quoted An element can optionally contain one or more attributes in its start tag. An attribute is a name-value pair separated by an equal sign (=). Attribute values must always be quoted.
Example with an image we could have;
<img alt="anything" src="anything.jpg" />
Notice that the attributes, alt & src have been quoted.
ID attribute replaces the Name attribute
Example with the image above
<img alt="anything" src="anything.jpg" name="anything" /> Incorrect
<img alt="anything" src="anything.jpg" id="anything" /> Correct
Attributes cannot be minimized
Example with form items;
<input type="radio" checked /> Incorrect, checked has no attribute
<input type="radio" checked="checked" /> Correct
