A: First, it is not a good idea to change link colours on a page. Users tend to identify links with a standard, fixed colour and may ignore text with a different, varying colour. People with visual impairment may also find it difficult to read the text, especially if it is the same as the custom background colour they have chosen. It is therefore important to ensure the background colour is set with the foreground colour.
The example code below creates an array of 4 named colours, a delay of 5000 milliseconds and uses the setTimeout() method to trigger the colour change. A reference to the link is obtained by assigning an id attribute to the anchor and using the DOM1 getElementById() method. The existence of the getElementById() method is checked before setting the style.color and style.background properties of the element.
