Evaluate your site - Accessibility
Accessibility is a concept linked to the usability, respecting it, we scrupulously follow all the rules drawn up by section WAI (Web Accessibility Initiative), of the World Wide Web Consortium, better known by the acronym W3C, which, from about 10 years, defines the development standards in order to make the web a tool truly democratic and universal.
When a website is considered accessible?
A website is accessible at the time it is accessible by users with disabilities of various kinds; indeed in the design of a site must always keep in mind how the user perceives the colors and sounds, whether or not he has the opportunity to use the upper limbs, and tools to allow screen readers to make the site accessible to the blind, this is the only way to make a site accessible to all
In 1999, the W3C suggests guidelines that define standards for accessibility of web content in order to break down e-barriers, be they sensory or visual.
These rules, which concern the accessibility of a website, are many specific rules, that the webmaster must implement to create a truly accessible site
The rules are available on http://www.w3c/WAI
It must be in mind that also comply with those rules of usability and accessibility and structuring the site with contents based on principles of simplicity and comprehensibility, it is not neglecting the pleasantness, the visual impact, the particularity of the website. It is also important the optimization of all images and photos including on the site that they are bmp, jpg, gif, or png, for them to display even to those who do not have an internet connection at high speed.
One of the most important things, to have more visibility, is to allow anyone to access and view our website.
Automatically check the accessibility of your website: If you want to know if your site, despite the promises of your webmaster (the person who creates web sites), is accessible, you can safely use automated tools.
Unfortunately WebXACT service is no longer available for some time, so if you want to check the accessibility of your website you can use EVALACCESS a replacement of WebXACT and equally professional. (Simply enter the URL of the page to verify and check that the errors are zero for all 3 priorities, and A, AA, AAA.) (The warning, however, are simple notices to be verified manually).
Very important is the use of the Accessibility toolbar, an excellent tool to test and control many aspects of accessibility of a website.
For Accessibility on the colors you can see the section "Graphic and Web Design" where you can find semi-automatic tools to verify your website as Vischeck or Color Contrast Analyzer and also the bar of accessibility.
Equally important, the addition of keyboard shortcuts called access-key to replace the mouse with the keyboard, simply by pressing a number key (usually Ctrl + a key +Enter), you can navigate through the entirety the website.
Moreover, the "tabindex" which is the path that the "tab" must be followed when the keyboard is pressed. Try to press "Tab" key on your keyboard, if the links are followed by a test goes well, otherwise they are not being disclosed.
It must be created over an alternative style to the original style of the website, designed with a higher contrast, with different fonts and text fonts, larger and more readable, to allow to potential surfers with low vision to see our website.
It should also not be overlooked those who suffer from blindness, and then
the website should be achieved by studying the best way, in order to make that
speech programs, which allow to automatically read a text on the web, they can
see and read it in a manner consonant.
