If u have more slots just copy paste their desc

For design purpuses u can use div#google_ad_div_SLOTNAME_ad_container - this div creates if there is ad, so u can do something like:

<!-- Marketing_VacList_240x400 -->
<script type="text/javascript">
  GA_googleFillSlot('Marketing_VacList_240x400')
</script>
<style type="text/css">
  #google_ads_div_Marketing_VacList_240x400_ad_container {
    background: #ccc;
    padding: 10px;
    margin: auto;
  }
</style>

Or even use js to do whatever u want

GA_googleAddAttr('region', 'kiev')
GA_googleAddAttr('region', 'lviv')

Notice:

keys - must be 10 characters length, only alphanumeric and underscores allowed,
