Every time an article--such as this--is posted somewhere, it's immediately followed by a series of responses where one is unable to make a web page work the way they want it. Often there is no representation of the markup they used. More often the markup they show is invalid and nonsensical. In other posts about programming languages, you can't write invalid code because the compiler will complain and stop. When the browser fails to render your HTML, one complains about HTML and rants about how it was developed in the 1990s while forgetting that their own programming language might have been developed long before that. I've been developing web sites commercially for 25 years. I have no such issues making highly performant, modern and cool web sites.
