If you’re using responsive adsense ads with certain wordpress themes you’ll notice a yellow background behind the ads. It’s fairly easy to fix, the issue is the <ins> tag has a background of#fff9c0 in your theme’s css file. The adsense code is also using the <ins> tag. The adsense code also has a default class on it of “adsbygoogle” so i went ahead and added a background style of #fff on that and you can see it overriding in chrome inspector now. Fixed.
Solution CSS:
.adsbygoogle { background: #fff; }
