How can I center the output from some javascript?

On my site, I'm using the following advertising tag:

<script type='text/javascript'>
GA_googleFillSlot("Skyscraper");
</script>开发者_Go百科;

How can I get that "Skyscraper" to be centered, rather than range left (everything else in that zone is properly range left, but the skyscraper is narrower than the column, so I need it to center)?

I have no idea what that outputs, but you might be able to do...

<div style="margin: 0 auto">
    <script type='text/javascript'>
    GA_googleFillSlot("Skyscraper");
    </script> 
</div>

<div class="ad_container">
   <script type='text/javascript'>
      GA_googleFillSlot("Skyscraper");
   </script> 
</div>

and

.ad_container div {
   text-align:center;
}

worked nicely as the Google ad has "display: inline-table;" on it.

Try with max-content

<div style="width: max-content; margin: 0 auto 0;">
    <script type='text/javascript'>
    GA_googleFillSlot("Skyscraper");
    </script> 
 </div>
