title: Toggle animation or Css
body: <p>How can I toggle an animation or css change? For example I wanted a button that when pressed changes the font size then when pressed again it will change back. I could of course use two buttons, but It would be nice to have one button. I tried changing the id of the button right after changing the font size and then having a separate function for the new id to change it back, but that didn't seem to work.</p>
  
  <p>Sorry, I'm new to Jquery :)</p>
  
  <p>Thanks!</p>
