This kind of goal, as sacramental as it might be, has not gained substantial support and proper attitude so far. Since a result, despite the accepted standards and the testing mechanism, passing this examination has nearly no practical influence on a website, and the website through no means "harmed" by not passing the test. Moreover, striving to meet the W3C requirements requires thorough and thoughtful code development according to extremely strict guiding guidelines, which is utterly not in line with systems designed to make this easy process.

Regarding search engines, no evidence has yet been presented indicating there is any immediate connection between meeting the W3C standards and search engine ranking (big reports sites with thousands of errors make the perfect piece of evidence). In contrast to that, there are much more important factors, such as keywords and address text rewriting, that may push you up to the summit of the search results.

Hence, a site constructor should better give full attention to the main and important factors, which affect website promotion and my browser size suitability, out from the set of hundreds less significant ones.

Try validating the primary websites on the web, major search engines like yahoo and news sites, and discover the vast amount of problems found by the validator. If they succeed in spite of these 'errors', one must ponder if the test itself is well-constructed...

What is CSS?

CSS is a computer language, which allows creating fixed design settings for a website, thus guaranteeing its imperturbable appearance. It is not a piece of wedding cake, especially for a starter, and requires some time resource and desire to grasp the basics. Even so, if you feel keen about it, feel free to learn more on the subject on multiple sites online. Here is one of these: http://www.w3schools.com/css/default.asp.

Performing tests

The best way of testing your website is downloading and installing a number of leading web browsers and trying to surf to your site using different configurations, changing resolution etc. Most web developers together use Internet Explorer, Mozilla Firefox, Apple Safari, Ie and others when screening their websites, while constantly changing resolutions and color settings during the practice of fitting the website for any pair of options.
