The element is:
span {
position:absolute;
float:left;
height:80px;
width:150px;
top:210px;
left:320px;
background-color:yello
If you are planning to hide show some span based on click event which is initially hidden with style="display:none" then .toggle() is best option to go with.
$("span").toggle();
Reasons : Each time you don't need to check whether the style is already there or not. .toggle() will take care of that automatically and hide/show span based on current state.
