As Roger Johannson writes: Note that "works in any web browser" does not mean "looks the same in every web browser." Making a document look identical across browsers and platforms is next to impossible.Not even using only images will make a website look exactly the same everywhere.Validating your Web page won't guarantee that it will appear just the way you want it.It only ensures that your code is free of syntax errors.Perhaps the most straightforward way to do this, is the way I do it all the time."View source" of the web page, select it all (ctrl a), choose "copy" (crtl c), tab over to the validator, and its "direct input" option, and paste it in (ctrl v). What if you have to validate a website with hundreds of pages? I run a website where most of the content is generated from Te X by a not-very-reliable Perl script.
I have an application server running on my local machine (Orion Application Server) and I'm connecting to web pages I've deployed on this server using a browser running on the same machine, directed to example).This makes the HTML Java Script environment a rather unique -- and often frustrating -- software development platform. There are provisions and mechanisms for validating your HTML markup through the official W3C Validator.Playing with the validator underscores how deep that forgiveness by default policy has permeated the greater web.Therefore, the best starting step to ensure a webpage appears and works as intended in all modern web browsers and web rendering softwares is to write HTML code adhering to the HTML 4.01 specification.Generally speaking, a webpage using valid HTML code along with valid CSS code is smaller in size (so downloading is faster) and is also rendered considerably faster in modern browsers.
