I’d like to change the colors of the mobile navigation menu to be like the Twitter Bootstrap style button you’ve included as part of the tiny-forge CSS. I see that it’s in the section “/* From Expound css/expound.css */” but I’m not clear on what to change / how to do it. Any tips?
Copy whole “Mobile menu” CSS part from Tiny Forge and apply changes. Overall I don’t recommend to mess a lot with mobile menu, unless you rename Parent theme, because future updates might introduce some changes. I consider mobile menu more or less out of the box element.
