Safari与Firefox：奇怪的UL“填充”

Question

I have this HTML:

<article class="images">
  <ul class="cf">
    <li>
      <a href="#">
        <img src="http://www.placehold.it/800x600" alt="" />
      </a>
    </li>
  </ul>
</article>

And this CSS:

 * {
  margin: 0;
  padding: 0;
}

 .images ul {
  margin-left: -3%;
  width: 100%;
  background: red;
}
.images li {
  list-style-type: none;
}
.images li img {
  width: 17%;
  margin-left: 3%;
  margin-bottom: 3%;
  float: left;
}

Still, in Safari the ul seems to have some kind of padding on the right.
In Firefox the ul is displayed correctly.

See it for yourself: http://jsfiddle.net/EdCXx/

Is there any way to fix that?

Edit: With Safari 6.0.2 on OS X 10.8.2 it looks like this:

I'm assuming the issue is that you're using negative margin and this is causing a problem (I don't have access to a Mac at the moment, so I can't verify).

Try changing your CSS to what's below. I also changed your clearfix to one I picked up a while ago that has had excellent cross-browser results.

CSS:

/* Reset */
* {
    margin: 0;
    padding: 0;
}

/* Clearfix */
.clear:after {
    clear: both;
    content: ".";
    display: block;
    height: 0;
    line-height: 0;
    visibility: hidden;
}

/* Images */
.images ul {
    width: 100%;
    background: red;
}
.images li {
    list-style: none;
    overflow: hidden;
    margin-right: 3%;
    margin-bottom: 3%;
    float: left;
    width: 17%;
    height: 17%;
}
.images li img {
    float: left;
    max-width: 100%;
    max-height: 100%;
}

And tighten up your HTML (not necessary, but it's prettier):

<article class="images">
    <ul class="clear">
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li><a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
        <li> <a href="#"><img src="http://www.placehold.it/800x600" alt="" /></a></li>
    </ul>
