Transparent White Area Only - Slider

notice the green arrow, I want this to stay, but is it possible for the circle part to be transparent? I'mnot sure how it would look on my site but as you can see it's overlapping some of the graphics on the slider I wish to try to remove so I can see how it looks please.

 

Hello,
It is not possible to do that with this theme through Custom Css because it is the single image, but you can edit next.png and prev.png image from the image directory (Theme Directory > image directory) with the help of photoshop or any other image editor tool.
This will solve your issue.

 

that answer is perfect thanks Piyush
