href target

<!DOCTYPE html>
<html>
<head>
<style>
:target
{
border: 2px solid #D4D4D4;
background-color: #e5eecc;
}
</style>
</head>
<body>

<h1>This is a heading</h1>

<p><a href="#news1">Jump to New content 1</a></p>
<p><a href="#news2">Jump to New content 2</a></p>

<p>Click on the links above and the :target selector highlight the current active HTML anchor.</p>

<p id="news1"><b>New content 1...</b></p>
<p id="news2"><b>New content 2...</b></p>

<p><b>Note:</b> Internet Explorer 8 and earlier versions do not support the :target selector.</p>
