As the most standards-compliant Web browser, Opera is dedicated to promoting Web standards across the globe. Web standards make the Web available to anyone, on any device, anywhere in the world.
Why should you incorporate the Opera WSC into your curriculum? Web standards in a Web site promote efficiency, ease of maintenance, accessibility, device compatibility, and search optimization. The Opera WSC features the most up-to-date practices in Web standards. Best of all, the course is free, requiring no expensive textbooks.
When Netscape started the Mozilla browser, it made the conscious decision to support W3C standards. As a result, Mozilla is not fully backwards-compatible with Netscape Navigator 4.x and Microsoft Internet Explorer legacy code; for example, Mozilla does not support as I will discuss later. Browsers, like Internet Explorer 4, that were built before the conception of W3C standards inherited many quirks. In this article, I will describe Mozilla’s quirks mode, which provides strong backwards HTML compatibility with Internet Explorer and other legacy browsers.
Testing your sites on different versions of Internet Explorer has always been notoriously difficult mainly due to the fact that Microsoft prevents you from running to different versions of the browser in Windows. Sure there have been solutions to get around this limitation but in my experience, they’ve always caused unexpected results and instability for the operating system or required you to run a VM. Not ideal.
Als je met webstandaarden bezig bent en er belang bij hebt dat al je pagina’s in orde zijn heb je de plicht om toch bijna elke pagina te checken in de W3C-validator. Dit kan een tijdrovende bezigheid zijn als je met 100+ documenten zit.
Okay, the Data Web (from the man himself – Tim Berners-Lee) is coming. Linked data will rule the day and if you don’t act quick your website will be left behind. Or more likely your site will simply go on strike demanding better work conditions and an observance of the fact that it is capable of oh so much more and you haven’t been caring enough to see it.
Unless you limit yourself to one-page web sites, you’ll need to design navigation. In fact, navigation is among the most important parts of any web design, and requires a great deal of thought if visitors are to move around your site easily.
Many web users don’t understand the inevitable consequences of exposing their e-mail address on the web. Experienced web developers and website owners, however do. Thousands of spam bots tirelessly crawl the web to collect e-mail addresses exposed on websites, in blog comments and elsewhere. These addresses end up in databases sold to unsavory marketers, who bombard the owners’s inboxes with unsolicited mail.
Of course, spam is an increasingly complicated problem that can never be solved by the efforts of web developers alone. But don’t underestimate your own powers.
One thing that is particularly frustrating with caring about Web standards and accessibility is what often happens after your work is done and a site is handed over to the client.
I’m sure most of you have been there. Despite your hard work to educate the client’s editor(s), regardless of the style guide you wrote, and no matter how much time you spent patching the CMS they use, there will be problems.
