nav div必须垂直固定,并且位于容器div的右侧。
使用position:fixed;
并设置值left和top,可以让div保持在同一个位置,但是左边的值取决于父div(page-container)居中。
<html>
<body>
<div id="page-container" style="width: 700px; height:1000px; margin-left: auto; margin-right: auto;background-color:moccasin;">
<div class="content" style=" width: 340px; height:300px; float:left;background-color:mediumseagreen;">
.content
</div>
<div class="nav" style="float:left;height: auto; width: 300px; display: block;background-color:lightblue;">
.nav <br><br>This div must:<br>
1. be fixed vertically (if scrolling down, you should see me in the same place) <br>
2. be aligned to the right side of <b>content</b>
</div>
</div>
</body>
</html>
