Case sensitivity of attributes and attribute valuesInsensitive.

However, the World Wide Web Consortium recommends lowercase attributes/attribute values in its HTML 4 recommendation standard.

However, the new version of (X)HTML requires the use of lowercase attributes.

Always quote attribute values

In some particular cases, such as when the attribute value itself contains double quotes, you must use single quotes, for example:
