Using Grid. Puzzling about Background Image and Testimonial Images

Hi,

there are a some details, I don't understand: 1.) Where to place the quotation marks? I think, it is neccessary to display them as background-image. Otherwise you need to set Opacity, which makes the Headline blurr. I tried first to put it in a div and place it absolute. Than I put the marks as background in heade. Problem: They are not displayed as in design. How to cope with this? 2.) Testimonial images behaves mostly okay. Except Jonathan Walters and Jeanette Harmon, when the containers are very small. How to tackle this? Best and stay healthy,

S.
