Unique Titling Rules

Markup

img[alt] (HTML4)

Using images to covery text content makes it difficult for people with visual impairments to restyle text content to their own needs, therefore images should not be used to style text content, use CSS instead.

h1 (HTML4)

title (HTML4)

title elements are used to describe both web site and sub page information
