W3C Compatibility – Is it Important?
The World Wide Web Consortium (W3C) is the main international standards organisation for the World Wide Web and is headed by Sir Tim Berners-Lee (the man credited with “inventing” the Internet).
W3C’s only goal is to ensure that the Internet and Websites work as well as they should. Their guidelines are extremely strict and focus on the concept of “accessibility for all”. Whilst it is not official (Google keep the formula they use for scoring and ranking websites a closely guarded secret) it is widely agreed amongst website developers that following these guidelines will help your website list higher on the search engines.The W3C themselves state “Following these guidelines will also help people find information on the Web more quickly.”Therefore if you wish to compete effectively on the Internet then your business needs a website that the W3C approve of – one which is web compliant.
You should test websites against these guidelines using W3C’s free online validation service at http://validator.w3.org. To do this you simply enter the URL of the web address you want to check.
If a website “validates” then it complies with W3C’s guidelines. If it does not “pass” the validator will declare the errors and any warnings. These errors and warnings can be used to identify the problems in the website’s code so that a web developer can address them. Often these are complex and detailed descriptions which may be unintelligible to a lay person.
From a coders point of view a W3C report is very beneficial because it includes a description on how to fix the problem in a way that should result in the website passing validation.
Errors
The most common error declared by the W3C Validator is know as a “Syntax Error”. HTML and XHTML are languages used within the coding of the website and W3C produce an approved list of commands (words that are used in the language). If a web developer has used a non-approved command or word, then a Syntax Error is produced. The website may still appear to work and display properly but it does not achieve the levels of accessibility required by the W3C.
Warnings
Unlike errors, warnings are generated when the W3C validator is unable to make sense of the coding the developer has used. It is sometimes the case that the commands used are so different from the list of approved HTML and XHTML commands that the W3C are unable to give the developer advice on how to address the problem. Even more seriously, this could mean that the website has the potential to crash or not display properly. This guide is a relatively simple overview of an extremely complex and highly technical subject usually reserved for well qualified website developers. It is therefore important that we bring to your attention some additional details about W3C guidelines that are relevant on certain occasions.
Levels of Validation
There are several different levels of validation and you should ensure that your website conforms to at least level 1 of the Guidelines. You could also work to higher levels if you want to, which may include providing visitors with the ability to increase the size of the font on the website to make it more legible. You can also ensure your website is “screen reader” compatible (screen readers give the website a ‘voice’ and read the content of the site to the visitor).
Content Management Systems and Validation
Many websites now support the use of a Content Management System (also known as a Content Editor) which allows people with little to no web development skills to create and manage content on their website quickly and easily.This means that what was once the preserve of those with considerable technical expertise is now open to anyone with basic computer skills.
Content Editors, do, however, have a very tricky job on their hands as they have take all the raw text, images, links, tables, bullet lists, etc. that you throw at them and by using a combination of processes and formulas, convert this raw data into HTML and/or XHTML code that is approved by the W3C. Whilst this is easy for a web developer to do, because they have prior knowledge of what is and what isn’t “valid” code, it is very difficult for an automated system to do and often leads to shortfalls. For reference, around 95% of validation errors on our websites originate from a content editor. You can avoid many of these problems by not cutting and pasting copy directly from Word for Windows into the Content Editor.
This is because Microsoft Word for Windows contains huge amounts of hidden information that can interfere with the HTML and/or XHTML code on the website. We always recommend that you first cut and paste from Word into a more simple word processor such as Notepad. You can then re-cut and paste from Notepad into the Content Editor and avoid many validation errors. This is often the case and it is an issue that is often experienced by many web designers across the world.
It is therefore very important that whenever you or your client create or change content on a website you also check that it still validates. It it doesn’t, then your website designer should be able to look into it for you.
