Default :target with CSS

Issue

I have this CSS:

<style type="text/css">
.tab {
  display: none;
}
.tab:target {
  display: block;
}
</style>

And this HTML:

<div class="tab_container">

  <ul class="tabs">
    <li><a href="#updates-list">List</a></li>
    <li><a href="#updates-map">Map</a></li>
  </ul>

  <ul class="tab list" id="updates-list">
    Eh.. Hello!
  </ul>
  <div class="tab map" id="updates-map"></div>
</div>

However, my page is empty if no target (# in URL) is specified and no tab is clicked yet. I want to show ul#updates-list by default.

How can I do this? Thanks.

Update: Next to this, my Google Map is broken if it is not the initial target. Does anyone know a fix?

Solution

Spontaneously I'd have to say that the only solution I can think of is unfortunately using JavaScript. Something like:

<script type="text/javascript">
  if (document.location.hash == "" || document.location.hash == "#")
    document.location.hash = "#updates-list";
</script>

EDIT:

Ok, got a CSS solution. This however requires the default entry #updates-list to be placed last (after #updates-map and any other tabs you may add):

.tab, .tab:target ~ #updates-list  {
  display: none;
}
#updates-list, .tab:target {
  display: block;
}
