Checking the markup of W3C member sites

Considering the possible difficulties with traveling to an interview with a well-known company, I planned one hour as a spare time. Two trains did not arrive and the time ran out quickly. In the invitation, instead of a phone number and an email, there was a link to a corporate website where you can send a message to any employee.



It turned out that the site lives its own life if you open it from a mobile phone. As a result, it took me 20 minutes to simply send a late message and a quarter of the battery charge, which was only half before.



This was the case when the technology I came to trust failed me.



Later I noticed that technology began to fail more and more often and began to rely less on it.



In many cases, the reason is a simple mistake in organizing Internet sites.

We are increasingly using mobile phones and mobile Internet, the resources of which are limited. Quite simple sites are overloaded with ads, trackers, libraries, animations, gigantic pictures, and have a lot of mistakes.

More and more often, it just doesn't work.



Interestingly, the internet is also overloaded with all sorts of advice, SEO, rules on how to do it right. There is even an organization dedicated to improving the internet.



Members of the W3C club



Despite criticism of the organization, it is dedicated to Internet standardization and provides many free resources. It has over 400 participants.



I wondered how the club members themselves relate to their sites.

Below are the results of experiments to test their layout using validator validator.w3.org .



Results of checking the markup of W3C member sites







Without checking (value -1) there were addresses that were entered with an error in the list of participants or did not allow themselves to be analyzed. The latter include, for example, facebook and google. It can be explained by the peculiarity of their business model. Although Youtube can be checked and shows 53 errors, one of them is listed as fatal. 23 sites turned out to be



completely error-free . This is about 5%. Confirms the inner feeling that this is how much Internet is working normally.



Up to five errors are shown by 88 member sites.



The other 297 members do not seem to care much about the standards on their sites. Maybe because the giants don't have time for such little things.



For example, Habr's check shows 61 errors.



Output



More and more services are moving to the Internet and only a small part inspire confidence due to their functional ability in limited conditions.



If site builders, search engine and client optimization specialists try to pay more attention to functionality and errors, not to turn Internet pages into cartoons, then the situation can still be improved.



But this applies to the non-European Internet, which cannot be saved after the second version of the law on "cookies" was issued.



Links



A good example of an organization that actually improves the Internet, you can call w3schools .



In the CSS templates section you can download design examples for free. The technologies are well structured and described.
