Please help me. I feel like such a beginner. I should be easy but I just cannot find how it works. I work in theme twenty fourteen, that should have a flexible header. Still I always have to crop my picture and so I get a white empty space on the side of my header. I wold like to header to fill the whole width of my blog. I cannot work in css and did'nt buy the upgrade.
The blog I need help with is annelissen.wordpress.com.
