Answer 1

?A hyperlink link color changes due to the use of pseudo-classes in a style sheet.Pseudo-classeschange the style of a link based on four link states: link, visited, hover, and active.A unique style for normal, visited, hover, and active links is defined by creating four separate style rules with a:link, a:visited, a:hover, and a:active as the selectors. A pseudo-class is attached to a selector with a colon to specify a state or relation to the selector to give the web developer more control over that selector.?The colon (:) is part of the pseudo-class and is placed between the selector and the pseudo-class.?The following is an example of a navigation :link pseudo-class:nav a:link {color: #FFFFFF;}The selectornav a:linkidentifies the color to apply to a navigation link that has not yet been visited or clicked. In this case, the initial link color is white.?The following is an example of a navigation :visited pseudo-class:nav a:visited {color: #000000;}The selectornav a:visitedidentifies the color to apply to a navigation link that has been visited or clicked. In this case, the link color is black.?The following is an example of a navigation :hover pseudo-class:nav a:hover {color: #FFFF00;}The selectornav a:hoveridentifies the color to apply to a navigation link while the pointer is hovering over the link. In this case, the link color is yellow. The :hover pseudo-class enhances the interactivity between the user and the webpage.?The following is an example of a navigation :active pseudo-class:nav a:active {color: #0066CC;}The selectornav a:active?identifies the color to apply to a navigation link when the link is being clicked or when it gains focus.
