A selected state is usually found in a list of navigation links to show what link is selected at that moment. This is a great way to show a user where they’re at within the site. For example if a site visitor is on the About Us page, the “About Us” link in the header would have some sort of selected state activated. The text may be bold, underlined, a different colour or all of the above.
Anyone who has been marketing online knows that the lifeblood of a business is the traffic of a site. More visitors equal more sales.
