  $( function() {

    $( "p" ).click( function() {

      $( this ).css( {

       "background": "gold",
10
       "font-size": "+=1.5em",

       "padding": "+=10"
12
      } );

  });

<p>Click me.</p>
17
<p>Using jQuery relative values such as <code>+=1.5em</code> adds that amount to the current value.</p>
18
<p>Clicking the element continuously will result in the value being incremented continuously.</p>
