In fact, I've done a project that creates tab dynamically. For example, when you each time click on email button, it creates a new tab and also in the new tab there is ('x') symbol to remove that. Indeed, I want to prevent click event triggering multiple tabs. If a user clicks on 'x' symbol .so, I can create a new tab.

#mainTab li span {
position: relative;
top: -31px;
left: 5px;
}
