We’re rebuilding our pre-Cornerstone X Theme website using Cornerstone to future-proof it. Our previous website (www.shapesdesign.uk) was based on a Renew stack, but we’d prefer to base the new website on Ethos but we’d like to change the header menu from the key-line appearance of the menu buttons of Ethos to the solid button look of Renew, as per our existing website. We’ve downloaded the child theme but don’t know where we can edit this part of site. Can you help?
