hi
we define margin as a part of box model of the element but what happen when i define margin for an element that don't have any sibling, are margins of that element affected?
for example see the below example:
	you can see above example at http://www.w3schools.com/css/tryit.a...trycss_nesting,
i added margin: 10px; declaration to .marked p selector only.
In above example we have a p element that is matched with .marked p selector and this element doesn't have any sibling , I define margin: 50px for that but this margin is not affected because background-color of div element with marked class is spread under the p element without any margin for that, is that for the sake of no sibling exist?

background-color:red;
}
.marked p
{
color:white;
margin: 50px;
}
</style>
</head>
<body>
<p>This is a blue, center-aligned paragraph.</p>
<div class="marked">
<p>This p element should not be blue.</p>
</div>
<p>p elements inside a "marked" classed element keeps the alignment style, but has a different text color.</p>
</body>
</html>
</CODE>
