I’ve recently changed themes on this site, from my own development of P2 Categories to Automattic’s TwentyThirteen. P2 Categories was not mobile friendly by default, and TwentyThirteen gives all my major notebook sites a cohesive look, making maintenance easier for me.
One thing I’ve noticed about TwentyThirteen is a small bug that’s been discussed several times around the web: when no header text elements are shown (under Appearance – Customise – Site Identity), a graphical header image disappears on mobile devices. Or more accurately, when the screen width changes to anything below 767 pixels.
If a site title and description are shown, the bug does not present itself, and instead the theme resizes the header image as well as the text without issues. That’s the behaviour I’m experiencing on both my 3D Dev Diary and my iOS Dev Diary.
I did some digging and found a suitable solution for this problem. Let me share it with you here.
