It must work
Websites, apps and e-stores. The very core of the Internet. In other words, we code, position and do all sorts of important things to ensure flawless performance but you do not necessarily need to know names of things. They have to work. On all platforms ( both PC AND Apple) - and yes, they make a difference in website creation, smartfones, tablets, etc.
It must look good and direct your audience
There's no need to deceive ourselves - appearance is important. But so is content. We have fantastic graphic designers, or, even more than that, we have creators. They're visionaries. It's big luck to work with such people. Good taste and style, championship of the world and of the Adobe packet. Amen. Logo, publications, layouts, all designed by the customer following the rules of psychophisiology (why I want to buy).
