Hamburger Menu Button Styling

Hi All,

Newbie here so apologies if this is a simple question.

I have styled my hamburger menu button as follows:

However, when I preview it and click on the hamburger, I get this unwanted result:

Can anyone give me some pointers on how to eliminate those corners around the hamburber button so that the background shows through just as it does before being clicked.

PS - My navigation wrapper is inside my hero section.

Hope you can help.

Cheers,

Helena

Never mind. I found it. If anyone else has a similar issue. You need to edit the background of the Menu Button Container rather than the icon itself.
Hope that helps someone.
