<html> <body> <h1>This is heading 1</h1> <h2>This is heading 2</h2> <h3>This is heading 3</h3> <h4>This is heading 4</h4> <h5>This is heading 5</h5> <h6>This is heading 6</h6> <p>Please only the title tag for the title text. Not just to produce bold text and use them. Please use other tags or CSS instead. </ P > </ body > </ HTML >
