The code is as follows:

This code, the search engine to see a black background there are some white text, this is not cheating. But the user sees is a piece of white, do not see inside of text. The reason is to use a white picture as the background. In a table-layout Web page, if you also define a table's background color and background picture, it is preferred to display the picture color. In this way, the user sees a white background of white text, of course, can not see these words. This cheating method uses a point: the search engine has not yet recognized the color of a picture.
