Want to remove yearly and monthly from members sign up

Hello, 

dodecahedron-hypersphere-4xd3.squarespace.com

pw: 1234

I wanted to ask if it is possible to remove the upper part that says monthly and yearly. I only have the button option toggle on and that is the only thing that I want to have. I don't want to have monthly and yearly. 

Thanks a lot

Barbara

Hey Barbara, try adding this to 'Design > Custom CSS'
 

.member-area-block .ma-pricing-options {

display: none;

}
