"The website content is written by human beings: designers, copywriters, bloggers, and so on. But after being published on the Web, a web page is firstly read by robots: search engines, different web data aggregators and extractors, web statistical resources, and of course browsers. So, converting designs and texts into the website code, HTML/CSS coders are those who link the world of people with the world of machines and translate human ideas, emotions, and thoughts into a language understandable to the robots. It is an extremely important mission, eh :)?
In my opinion, it is the fact that makes the profession of HTML/CSS coders utterly attractive for many people. It forces people to be more versatile and use both hemispheres of their brain."
