Center a list vertically in a div

I want my navigation links to be in the middle of the parent div, vertically. How do I do that?

HTML:

<div id="nav">
    <ul>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
    </ul>
</div>

CSS:

#nav {
  background: #8DC3E9;
  width: 100%;
  height: 70px;
  border-bottom: 2px solid #4C88BE;
}

#nav ul {
  margin: 0;开发者_运维问答
}

#nav ul li {
  display: inline;
  font-size: 40px;
}

According to your comment to the other answer, you want them vertically aligned in the middle. Since you have a fixed height already, this should work:

#nav ul {
    margin: 0;
    vertical-align: middle;
    line-height: 70px;
}

I would just add a 15 pixel padding to the nav div:

#nav {
  background: #8DC3E9;
  border-bottom: 2px solid #4C88BE;
  height: 70px;
  padding-bottom: 15px;
  padding-top: 15px;
  width: 100%;
}

Also, I would highly suggest ordering your attributes alphabetically (as I've done above) so that people can more easily find the attribute for which they are looking.

Use vertical-align: middle; it is browser compatible.
