Within the template its Yellow Color Under The Adsense Widget

#google_ads_frame2 {
  background-color: white !important;
}

add this custom css. It will remove that.

On appearience “Edit CSS” Pasted the code

#google_ads_frame2 {
background-color: white !important;
}

didn’t worked!

Give this a try:

.entry .adsbygoogle {
    background: #fff;
}

Thanks It Worked
