Hi Tom,
I was also having problems with my header image (the image above the navigation) being responsive in mobile view. I followed your suggestion in this thread and separated the background image from the logo image. I uploaded the background image in the ‘Background’ section and the logo in ‘Site Identity’. Everything looks OK until I add the logo image. When I upload the logo image, the background image expands in width. I tried using different sizes of the logo image thinking that was the problem, but that didn’t help. I am new to WordPress so I’m sure it’s something simple. I followed other threads in the forum and tried adjusting the CSS, but that didn’t work either. I am using a child theme.
While I am here, I would like to ask a couple more questions. If I wanted to reduce the size of the images when viewed on a mobile phone, how would I do that. For example, If I am using a top header image above my main navigation and an image below my navigation (i.e. a slider or just a single image) how would I make those images appear smaller in mobile view. Not only responsive, but smaller.
Thank you,
Brenda
