HTTP/2 TECHNOLOGY DEMO This test consists of 200 small images from CDN77.com so you can see the difference clearly. SceneJS / Examples.
About the Demo
The Before and After Demonstration 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).
Note: This Demo is intended to illustrate some of the aspects of web accessibility. It does not cover every type of accessibility barrier or accessibility requirement. Some of the inaccessible Demo content may not be easily usable by all readers.

Using the Demo
This Demo serves a variety of purposes such as raising awareness on web accessibility or for providing practical examples for developers. Some of the common ways of using and navigating through the Demo include:
- Preparing presentations on web accessibility: Demonstrating practical examples during presentation is usually very effective. The description pages provide an overview of the accessibility barriers and features that are shown in the Demo. Together with the inaccessible and accessible Demo pages, concrete before and after examples can be explained during presentations.
- Learning about specific web accessibility barriers: Often web developers want to learn more about specific accessibility barriers. For example, what is the cause of a problem and how can it be fixed? While the evaluation reports provide detailed analysis, the inaccessible and accessible Demo pages provide implementation examples for developers to study.
- Understanding the implications of web accessibility barriers: In certain cases, the real issues for people with disabilities are not clear to developers or managers. Browsing through the inaccessible Demo pages using different browser configurations or assistive technologies (such as screen readers and magnifiers) helps highlight these issues. The accessible Demo pages can be browsed in the same manner to show the difference.
- Writing detailed reports of conformance evaluations: A well written evaluation report is key in the process of retrofitting websites for accessibility. It communicates the problems to managers and the developers who need to decide which solutions to implement. The evaluation reports of the Demo serve as a sample format for evaluators.
The Robot Operating System (ROS) is a set of software libraries and tools for building robot applications.From drivers to state-of-the-art algorithms, and with powerful developer tools, ROS has what you need for your next robotics project.And it’s all open source.
Since ROS was started in 2007, a lot has changed in the robotics and ROS community.The goal of the ROS 2 project is to adapt to these changes, leveraging what is great about ROS 1 and improving what isn’t.
Here you will find the official documentation on ROS 2, the newest version of ROS.
If you’re looking for documentation on ROS 1 (i.e., ROS as it has existed for several years, and what you might be using right now),check the ROS wiki.
Where to start¶
Newcomers and experienced ROS users should consult this overview of our user-centric content to find what they’re looking for.
Installation pages will help you setup ROS 2 for the first time.You can choose your platform as well as the installation type and distribution that suits your needs.
Tutorials walk you through learning ROS 2,whether you’re learning from scratch or looking for guidance on achieving more specific goals.
Concepts are high-level explanations and background information on core ROS 2 concepts,which should provide some context for topics covered in the tutorials.
Troubleshooting guides cover some specific common cases where issues can arise.
Contributing is what makes ROS 2 great!We have guides on best practices and methodology for contributing new ROS 2 content as well as migrating existing content from ROS 1 to ROS 2.
Getting help is always encouraged.Here you’ll find several ways to get answers to your questions or start a discussion.
Learn more¶
There are plenty of resources available online to learn more about ROS 2.Here’s a few to start with:
