I’ve got a header image (1180 x 120px), and a custom logo (270 x 89px). Viewed on a mobile the effect isn’t good, the header image scrunches up beneath the logo and makes the logo very indistinct. i.e. it’s a mess!
Below a breakpoint of, say, 600px window width, I’d like not to display the header image and just have a black background colour, against which my logo will display well.
Can I do this in Tempera? If I have to throw some custom CSS at it, what would this be? (I’m not a css guru!)
