Html Attributes

HTML elements can have attributes
Attributes provide additional information about elements
Attributes are always specified in the start tag
Attributes usually come in name/value pairs like: name="value"
Always Use Lowercase Attributes
Double quotes around attribute values are the most common in HTML, but single quotes can also be used.
In some situations, when the attribute value itself contains double quotes, it is necessary to use single quotes
Boolean attributes are attributes without values. Boolean attributes can only have one value which is generally the same as the attribute name.
