Remove Yellow Background from Google Adsense Adverts

Microsoft Dynamics 365 Business CentralI’ve been hosting adverts from Google Adsense for a while and, after my last site redesign, I started using responsive adverts which scale according to the size of the browser window (or device size).

Since then, I’ve had yellow background showing either side of the adverts:

Adverts with yellow bars

The other day, I finally had time to track down and fix the issue. The html code for the adverts, which is supplied by Google, places the adverts within an ins tag and a class of adsbygoogle (see two highlighted sections):

...<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
				<!-- azurecurve Responsive Leaderboard -->>
				<ins class="adsbygoogle"
					 style="display:block"
					 data-ad-client="{adsense publisher id}"
					 data-ad-slot="5299901990"
					 data-ad-format="auto"></ins>
				<script>
				(adsbygoogle = window.adsbygoogle || []).push({});
				</script>...

The yellow background is the default colour used by WordPress for ins tags; so to remove it, all you need is a snippet of css in your stylesheet:

ins.adsbygoogle {
	background: transparent;
}

With the css saved, the yellow background disappears:
