I have this adsense ad code:
<script async src="http://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<ins class="adsbygoogle"
style="display:inline-block;width:728px;height:90x"
data-ad-client="ca-pub-xxxxxxxxxxxxxxxx"
data-ad-slot="6440411535"></ins>
<script>
What is a data-ad-slot
for Google Adsense and why is inline styling required — aren't all ads have a fixed mobile-first styling?
This question is very much a follow up to this question.
