Determining Element Page Coordinates, Part 4
IE Win - Final Comments

Bordered Static Elements with Width/Height

 

This time the red square is nested in a static element that has a width value.

Move the blue square.



  

<P STYLE="border:5px green solid;
          width:230px"
          padding:10px;>
    <IMG ID="redbox"
         SRC="redbox.gif"
         WIDTH="200" HEIGHT="200">
&lt/P>
        


Result

By adding a width (or height) value to the P element, we have given it "layout" properties.

In the IE5+ scheme of things this means that the element also defines a co-ordinate system and is part of the page's element offset hierarchy.
This is discussed in the MSDN documentation in the section Size, Layout, and Location of Elements.

Therefore, in IE5+, our position calculations are incorrect in both directions.

Let's try the example with a positioned element.
