The site I am currently developing is supposed to have a burger/mobile menu for all screen sizes, so I selected the last header type ( #19 )
With the light header type option selected I can see that the menu is there (mouse pointer changes on rollover) but it is white on a white background.
In WP additional CSS page I tried editing the CSS to
.hamburger-icon: { color: #414141 !important }
but it had no effect. Changing the background colour of the icon kind of works:
.hamburger-icon: { background-color: #414141 !important }
So I am nearly there – just not seeing the actual menu.
I tried looking at previous answers and they refer to a header builder and something called WCAG, which I don’t appear to have. What is that?
