My site: http://www.citiesagenda.com when I mobile view using Firefox with 320x480px, the image didn’t fit in as per text. When I build the web offline, I thought the issue was I manually add to Epik folder not WP uploader yet the results are the same with the online version.
I don’t quite understand what you’re asking….but if you’re referring to the image on your homepage, take a look around line 390 in your css and change “auto” to 100% –
