What is the difference between using top and left properties and top and left margins?
I know top and left are usually used in position:absolute situation but I'm still wondering if there is any major difference.
ex:
position:absolute;
top:5px;
left:5px;
-vs-
margin-top:5px;
margin-left:5px;

Well, the main difference is that absolutely positioned elements are pulled out of the content flow.
But also with relatively positioned elements, the surrounding content may become obfuscated.
Margins on the other hand are added to the element's size while the surrounding content flows accordingly.
See this sample fiddle with some differences.
Surely there are situations where both deliver the same results, but under normal conditions, these two aproaches aren't simply exchangeable nor comparable.

A There's a semantic difference. Box offsets like top specify how far a box's margin edge (dotted edges in the image below) is offset from a reference edge (For absolutely positioned elements, that's the top edge of the box's containing block). Margin properties like margin-top specify the width of the margin area of a box (The distance TM between the dotted edge and and solid edge in the image below).
B top and left apply only to positioned elements (elements with position set to anything other than static) while margin-top and margin-left apply to all elements except elements with table display types other than table-caption, table and inline-table.
