Why some websites don't work properly in your favorite browser
It never fails: No matter which browser you use, and how well you keep up with its updates, sooner or later you end up finding a website that doesn’t quite work the right way. Even more frustratingly, bugs and defects always seem to crop up more often on sites that tend to push the limits of what can be done with a browser, with activities like printing, interactivity, and complex animations frequent targets of malfunctions and misfirings.
It’s easy to blame Web developers for being lazy and allowing these problems to occur, but the reality is that the Web has become a complex, well, web of technologies and competing interests that are, sometimes, at odds with the goal of writing software that works across as many platforms as possible.
A fuzzy standard
Web pages are programmed primarily using three different languages: HTML, used to define the structure of documents; CSS, which determines the way they look; and JavaScript, which is used to drive interactive features.
Of these, the first two are “managed” by a non-profit organization called the World Wide Web Consortium, or W3C, that is responsible for defining the standards that—in theory—browser manufacturers and developers must follow in order for their products to be compatible with each other.
