position-left vs margin-left

[Mark and two Cats]

What's the diff between eg: position-left:10px and margin-left:10px They seem to do the same thing. Thanks from a newbie! Best Regards,-Mark and two Cats

If you use position, then the element is allowed to occupy the same space as other elements that are surrounding it. This allows for overlapping which is usually not desirable.

Have you copied that correctly? There is no position-left property. There is a left property, but it can be used only when the position property is set to something other than the default value, which is static.

As Ingolme suggested, to make left or right coordinates work, you have to use some positioning mode other than the default mode. For some things this is necessary, but for a garden-variety page, it's best to position elements with margins and floats (if you need them). We're always fielding questions from people who use absolute positioning and suddenly discover their page is ruined if it loads into a display with a different resolution.
