Tools might have got better but.. it hasn't got any easier to develop for the web. To be a web developer today you need to know the ever changing HTML/CSS Specifications, have a good understanding of Javascript, be fairly good with the backend platform you use, have some design aesthetics, know the HCI basics for UI design, be up to date with the mobile browsers, have knowledge of a couple of SQL or NoSQL data stores, knowledge of web security and maybe even have knowledge of cloud hosting services.
Of course in big projects developers/designers only take up one of the above tasks but in most down to earth projects handled by smaller companies and startups you need to be an all-around expert to keep things running.
