What does validating a web page mean
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.Unfortunately, not everyone's browser will support the spiffy Java Script menu behind that innocent-looking button.If your browser won't display the menu, just click on the button and you'll be taken to a separate page with the entire menu displayed in clear, non-Java Script HTML.They were supposed to say “This is a header”, or “This is a less important header “, or “This is a paragraph “, and by using tags.The layout of the document was supposed to be taken care of by the browser, without using any formatting tags.
On the front page of the W3C’s Web site is a sidebar called W3 A to Z, which contains all sorts of links.These technologies, which we call "web standards," are carefully designed to deliver the greatest benefits to the greatest number of web users while ensuring the long-term viability of any document published on the Web.— Web Standards Group Even the most proficient Web designers sometimes fail to validate their documents — checking a Web document against the existing, DOCTYPE-specific technical specifications. HTML and CSS validation does not guarantee perfect Web documents, and some truly heinous Web sites can be designed that are completely valid.can be used to separate design from content, making websites easier to use and ultimately, maintain.It can also help with download times as the CSS is downloaded only once and held in browser cache. ) website development technique is to build your pages using HTML and link this page to what is called an external CSS file that controls all elements of style on the site.
