HTML properties often refer to property values

Property values should always be included in quotation marks.

Double quotes are the most commonly used, but there is no problem with using single quotes.

HTML properties Tip: In some individual cases, such as when the property value itself contains double quotes, you must use single quotes, for example: name'John "ShotGun" Nelson'

HTML Tip: Use small-case properties

Properties and property values are not case sensitive.

However, the World Wide Web Federation recommends smaller properties/property values in its HTML 4 recommendations.

The new version of (X) HTML requires the use of small-case properties.
