style object's left and top properties. Although these properties denote physical measurements, they are strings. The string includes a number followed by the string "px". The following strings are example values of the left and top properties: 50px, 32px, and 0px. When setting these properties, concatenate the "px" string to the value. For example, to set the left property of an element with ID="counter1" to xlocation, you will write:
document.getElementById('counter1').style.left = xlocation + "px";
The browser won't complain if you omit the "px" string:
document.getElementById('counter1').style.left = xlocation;
The browser assumes the unit of measure is pixels and will add the "px" automatically. You'll always get a "px" ended string when querying the top and left properties.
