<Div id = "content"> <SPAN class = "out"> </span> <SPAN class = "iner"> </span> <SPAN class = "right"> </span> <p> no matter what content is written, in short, it is necessary to implement a small triangle without a figure. If there is a background color, it would be excellent. If there is no background color, it would be a little troublesome. </P> </div>
