HTML Attributes
Attributes provide additional information
about HTML elements.
HTML Attributes
- HTML elements can have attributes
- Attributes provide additional information
about the element
- Attributes are always specified in the start tag
- Attributes come in name/value pairs like: name="value"
Attribute Example
HTML links are defined with the <a> tag. The link address is provided
as an attribute:
(You will learn about links in a later chapter of this tutorial)
Always Quote Attribute Values
Attribute values should always be enclosed in quotes.
Double style quotes are the most common,
but single style quotes are also allowed.
In some rare situations, like when the attribute value itself contains
quotes, it is necessary to use single quotes:
name='John "ShotGun" Nelson'
HTML Tip: Use Lowercase Attributes
Attribute names and attribute values are case-insensitive.
However, the World Wide Web Consortium (W3C) recommends lowercase
attributes/attribute values in
their HTML 4 recommendation
Newer versions of (X)HTML will demand
lowercase attributes.
