I'm fairly new to jQuery, but I thought this would be simple enough to add an onClick function.   
But for some reason it's not working. I'm thinking it's something little that I am overlooking. Also, I would like the div-1 to fade in slowly so it doesn't just appear right away.. But for some reason I can't even get the show to work.
Here is my html:
    <button id="button-1" style="height: 50px; 
width: 50px; background: red;">Click Me!</button>
    <div id="div-1" style="height: 400px; 
 width: 400px; background: blue; visibility: hidden;"></div>
and the jQuery
jQuery('#button-1').onClick(){
    jQuery('#div-1').show();
}
