HTML Attributes
Attributes are additional information provided by HTML elements.
HTML elements can set attributes;
Attributes are generally described in the opening tag; attributes always appear in the form of name/value pairs, such as: name="value".
Attribute values should always be enclosed in quotes.
Double quotes are the most commonly used, but there is no problem using single quotes.
Note: In some individual cases, such as the attribute value itself contains double quotes, you must use single quotes, for example: name='John "ShotGun" Nelson'
