They probably work in popular browsers. There are many web browsers and I guarantee you it doesn't work in at least one of them.
All browsers can read html. However, not all tags work the same on all browsers, with some being ignored and older browsers may show pages differently. Some browsers have tags that are designed specifically for them, so they should be avoided in favour of tags that work on all browsers.
Not all browsers are exactly the same. Some tags only work in some browsers and some tags work differently in different browsers. So it will depend on what code you have in your page. Try to use standard tags only and it should work on most browsers in the same way.Not all browsers are exactly the same.

As long as there is support for it, Javascript will work on all browsers and all Operating Systems
It is the fault of browsers that they support HTML or not. Some browsers support all the versions, while others none.
In general it isn't, but some tags were invented by particular companies to work only on their browsers. Netscape and Microsoft invented a lot of tags that only work on their respective browsers. As a rule of designing web pages, you should test your code on all the main browsers and avoid using the proprietary tags.
A website remains the same for all operating systems. All that matters is the web browsers that handles it.
Google Chrome will work on the same server settings as all other browsers.
