I am making a jquery shooting/aim game and I'm not entirely sure how to make the focus of the mouse shift to the center (i.e. the crosshair property), like so (the bottom line):   

```
#num {
    position: relative;
    height: 20px;
    left: 45%;
    top: -40px;
    text-align: center;
    width: 10%;
    background: gray;
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
    cursor: url(c_hair.png), crosshair; /* HERE IS THE PROBLEM */
}

```

THANKS!!!  

**UPDATE**  

I am trying to make the focal point of the cursor image in the center (with the crosshair or 'precision' cursor, for example), not the default top-left (with the pointer, for example).
