Day 25 Explore W3C’s Before and After demonstration.

-

 The World Wide Web Consortium (W3C) is an international community where Member organizations, a full-time staff, and the public work together to develop Web standards. W3C's mission is to lead the Web to its full potential.

On their website (www.w3.org) you can find The Before and After Demonstration page which is a multi-page resource that shows an inaccessible website and a retrofitted version of this same website. Each web page includes inline annotations that can be activated to highlight some of the key accessibility barriers or repairs. Each web page is also accompanied by an evaluation report to inform the developers on the level of conformance to the Web Content Accessibility Guidelines (WCAG).


Here are two pictures of the home page they use for their example (there are several pages with before/after examples). I used WAVE tool to scan both before & after pictures for better understanding.


As you can see in first picture we can see lots of error such as alternative text are missing for images & links, incorrect or incomprehensible alternative text (which could be accessibility issue for blind user who use screen reader) & colour contrast ( issue for colour blind user)


Second picture is a retrofitted version which have better accessibility.

                              Recently I did a presentation after almost 20 years at a Bootcamp showcase on Agile. As Agile celebrated its 20th anniversary this year I decided to talk on what Agile is? Below are the few drops from Agile's ocean which I managed to pour during my showcase. What is Agile Software Development? Agile is a time boxed, iterative approach to software delivery that builds software incrementally from the start of the project, instead of trying to deliver it all at once near the end. It works by breaking projects down into little bits of user functionality called user stories, prioritizing them, and then continuously delivering them in short time cycles called iterations.                In iterative development, feature code is designed, developed and tested in repeated cycles. With each iteration, additional features can be designed, developed and tested until there is a fully functional software application ready to be deployed to customers. Agile Manifesto
