Remove Adsense Yellow Block From Untitled Theme

Hi,

I’m running WordPress 4.0 and the WordPress Untitled Theme V1.1.3 (most recent). I have decided to add Google Adsense to my site and am using the WPInsert Plugin V2.0.12 (most recent).

For some reason when I add Ads to my site a pale yellow block is included around the adverts. I have Googled this and found that by adding the following code into the css, the issue is resolved.

ins.adsbygoogle {background: #fff }
}

However, the yellow block is actually pushing the Ads down so that a section of padding above the ad exists. The code above only changes the yellow block to white, the padding around the ad where the yellow block is remains. This makes placement of my Ads sub-optimal and in fact pushes the ad over the article text.

I would be super appreciative is someone would take a look at my site and let me know how I can completely remove the yellow block (not just colour it white).

I have left the ads live on my site. Here is an example URL: https://www.climbkilimanjaroguide.com/climb-mount-kilimanjaro/

Many thanks!
