i cant decide what is better, i used to use absoulte because i thought i have more control , but now i relize that when you change the size of the browser (manualy) my divs change there position. so i tried relative and from what i understand the relative means that the location is relative to the div that is written before in the html.

my problem is i am not sure that what i am saying is correct because in one case i have a few divs that i want to switch between them by using visibilty hidden and visible. so they are located one under the other in the html :

Code:

 <div id="Discription1" >
   <img src="images/prestentation1.jpg" /><br />
   some text<br /><a href="#" onclick="window.open('powerOfTen.html','window_name','scrollbars=no,width=820,height=600');">לצפייה</a>      </div>
 <div id="Discription2" >   
<img src="images/prestentation2.jpg" /><br /><a href="#" onclick="window.open('hamachpela.html','window_name','scrollbars=no,width=780,height=480');"> xome text</a> </div>

i am using the id="Discription1" in order to call them from javascript and also to add style

Code:

#Discription1{
position:relative;
margin-right:184px;
 margin-top:-215px;
}

so the relative is to the div before? so my margin-top should change from div to div right? i cant figure out how this works in this case....
i hope you had the patience to read this very very long question..
and help me not make it a monolog..

Not exactly. The element is positioned relative to it's nearest POSITIONED ancestor. So, if you have a #wrapper div set to position: relative, an div INSIDE #wrapper would be positioned relative to #wrapper - it's nearest positioned ancestor.

The error that most newbies make is to set positioning on everything or at least a lot more than is necessary. Better to learn to use the normal document flow and then only use positioning where it's really needed.

In the example you've given, #discription1 would be positioned relative to <body> unless you've got positioning on another element that #description1 is sitting inside of.
I can't tell what might be affecting #description2 without seeing ALL of your code.

all my divs are inside one main div named td

Code:

.
td{
margin:0 auto;
width:640px;
height:520px;
background-color:#42CBCC;
 border:1px solid #000000;
}

so description1 is relative to my td div but it looks like that only in the margin-right because the margin-top seems like being relative to the div written above it in the html. and here i have the problem, that it doesnt seem to work consistently...

It's NOT relative to TD because TD is not POSITIONED.
You misunderstood what I told you, positioning is relative to is nearest POSITIONED ancestor. The order in the document is not the controlling factor.

Why are you using tables anyway ? It seems pretty pointless to go so far to use divs and css and then stick the whole thing in a table. That's like putting a rolls royce inside a chevy body !

i am not using tables i just called my main warper div td......

Ok, then the name should be #td, not just 'td'. "TD" is the element and targets a table cell.
