That’s odd you need to look at the code of the website, when you created your own themes. The theme I have is literally the Fotografie theme unchanged. I mean, if I am the developer of my own code, I would know exactly which CSS to change to expand the width of the navigation menu bar.
So with that said, forget about it. I was actually considering buying the theme if it included this feature to change on the fly, but resorted to see if the theme can be changed manually. I’ll look for a different one.
Thanks.
