Question

Let’s suppose there are many divs inside a div:

<div id="#container">
 div div div div
</div>

the inner divs can be next to each other even. Now I want to have 5px padding between all of then, just like cellspacing of table.

Answer 1

you would do something like:

 #container div
 {
     margin: 0px 5px 5px 0px;
 }

or for only the immediate children:

 #container > div
 {
     margin: 0px 5px 5px 0px;
 }

if you want the divs to go side-by-side you have to float them:

 #container div
 {
     float:left;
     clear:none;
     margin: 0px 5px 5px 0px;
 }
