hej, mam problem z tym elementem: 
dokładnie nie mogę sobie poradzić aby te dwa elementy czyli obrazek i div po prawej były ciągle w 50% czyli takie same na wielkość, oczywiście w każdej rozdzielczości ( no może nie licząc mobilnych bo to już na media query zrobie ), i druga sprawa jak zrobić aby ten tekst w divie po prawo ciągle był wyśrodkowany w poziomie (chodzi o wysokość) oczywiście na każdej rozdzielczości bo te dwa elementy mają się zmniejszać wraz z niższą rozdzielczością.
