海外TECH	DEV Community	Introduction To Web Accessibility	https://dev.to/ezinne_anne/introduction-to-web-accessibility-51eb	Introduction To Web AccessibilityWeb accessibility has so many benefits that it offers online business owners and website owners One of these benefits is that it helps boost SEO on a site With accessibility you could reach a wide audience Web accessibility allows disabled people to visit and interact with your website which will boost your site and drive more engagements This article will cover What is web accessibility Importance of web accessibilityImpact of web accessibility on disabled peopleWeb accessibility guidelinesPrinciples of Web Accessibility The different levels of conformance A AA AAA Sufficient and advisory techniquesTools for testing web accessibilityBest practices for web accessibility What is web accessibility Web accessibility means making the content on the web easily available for everyone to use This includes People who have a hearing problem or cannot hear at all People who use logic or intelligence to solve a problem People with nervous disorders relating to the brain People with physical disabilities the ones you can see People who have problems speaking and seeing  It also includes People who have challenges with their health maybe they are sick and can t perform certain operations Older people have decreasing abilities because of age People who had an accident and sustained injuries Limited people maybe they are in a noisy place People with limited access to bandwidth Web accessibility aims to make it possible for people with the above cases and any other case that denies them equal access to the internet to create and consume content on the web Importance of Web Accessibility Web accessibility is important in many fields Here are some reasons why you should use accessibility right now Huge market valueAccording to the World Health Organization WHO about billion disabled people are living in the world This means that there is a strong market for disabled people to reach out to Also considering the poor accessibility on millions of websites in the world today disabled people would always love to patronize any website that promotes accessibility and makes the site easily accessible Improves the outlook of your siteWeb accessibility improves the user experience of your site Earlier on you came across many cases of people with special needs Applying accessibility to your site would cover persons with disabilities temporarily disabled persons and persons who are in an uncomfortable place at the moment If the regular users of your site who are not disabled can only use it when they are in a comfortable place then it s only a matter of time before they move to a competitor that removes all those barriers So implementing accessibility would improve the user experience of your site It keeps you out of legal troubleWhen running a business it is possible to get into legal trouble Not making your site accessible increases that possibility Companies like Netflix and YouTube have faced lawsuits based on the lack of accessibility on their sites This compelled them to implement accessibility Dominos had faced a lawsuit for failing to make the website accessible in the past These lawsuits are usually settled with money Instead of spending that money on accessibility legal battles it is better to apply accessibility and avoid all the legal drama Improves the reputation of your brandApplying accessibility goes a long way toward improving your brand s reputation It could be by recommendation People with disabilities usually have groups and communities they belong to In that community they could easily recommend your site to their members Facebook has earned praise over the years for making the content on its site accessible Also people will love to patronise your brand when they realize how inclusive it is The impact of web accessibility on disabled people Web accessibility improves the general experience of users with disabilities As a result they will have no trouble creating or using web content That way they can create or use the content on the web with no difficulty It also provides them with more online tools at their disposal which they could use to make a living or buy things online and enjoy the internet s services just like everyone else Finally web accessibility has encouraged many disabled people who couldn t use the internet before to use it reaching a wider audience Web Content Accessibility Guidelines WCAG The WC organization provides accessibility guidelines to ensure that websites follow through on becoming accessible These guidelines were developed by consulting with organizations and the WC These guidelines aim to reveal requirements that developers designers writers testers and every other team would follow to apply accessibility These guidelines comprise principles conformance levels and techniques to make a website compliant with accessibility Principles of Web Accessibility The principles are used to determine whether a site is accessible If a site does not follow the principles of accessibility then it is not considered accessible According to WC org the four principles of accessibility are Perceivable Web content which includes text images and so on needs to be presented so users can perceive and ingest the information Operable This means the web content and interface need to be operable by users with disabilities The users should be able to use the web components without hindrance Understandable Users should understand the content on the site and they should also understand how to navigate the site easily Robust The website should support assistive technologies and other devices used by users with disabilities to consume the internet The different levels of conformance A AA  AAA The WCAG has levels of conformity that identify whether a website is following the accessibility guidelines and they are Level A This is the ranking for minimum performance This signifies whether a site has met the basic requirements for accessibility Level AA This is the ranking for midrange This signifies that the website has met standards Some accessibility laws require websites to be at this level of compliance For a site to meet this level it must have level A success criteria in place Level AAA This is the highest level of conformance Like other levels to meet level AAA the website must first meet level A and level AA success criteria before meeting level AAA According to the WC this level is optional to meet as we usually use Level AA as an accessibility benchmark Sufficient And Advisory Techniques These are recommendations made by WCAG On how to meet the success criteria you constantly updated these techniques with each advancement in technology and the world These techniques could remove the challenges in the accessibility of a site These techniques are Sufficient TechniquesTechniques that fit the success criteria for the guidelines A website that follows sufficient techniques will address the barriers preventing accessibility Examples of such techniques are using alternative text on images using proper headings adding captions to videos and using well detailed navigation links Advisory TechniquesThese are techniques that do not meet the success criteria for the guidelines They are suggestions that could help improve the accessibility of the site Examples of such techniques includeusing CSS to make fonts larger instead of using heading tags and adding a sitemap Tools for Testing Web Accessibility There are some tools you could use to test the accessibility ranking of your site Ensure it meets the legal requirements and that people with disabilities can use your site to a particular degree Some of those tools are Web Accessibility Evaluation Tool WAVE This is an accessibility testing tool that was produced by WebAIM to test the accessibility performance of a site You can use WAVE as a web browser extension on Google Chrome Firefox and Microsoft Edge browsers You could also integrate WAVE as an API or a WAVE testing engine Accessibility Engine AXE AXE is an accessibility testing tool that you can integrate into a test environment when running tests AXE was produced by Deque to solve the barriers to accessibility It follows the guidance of WCAG to ensure a website meets conformance level A or level AA AXE has a vscode extension which could sort errors in the code while you are still writing code Firefox Accessibility Engine Fangs This is an accessibility tool made by Mozilla for the Firefox browser You can use the tool as an extension This tool makes it possible for you to read your text the way a screen reader would read it So you can improve the accessibility of your web page Best Practices for Web Accessibility Here are some best practices you could apply to improve the accessibility of your site Add alt text descriptions to imagesUse image descriptions to describe images when you use them Try to describe them accurately so that they can be heard by a screen reader Example lt img src gif png alt a woman sitting on an office desk facing her laptop in her office gt Use properly descriptive navigation linksWhen using links avoid using words like here or click here to describe your links As this is not perceivable strive to use descriptive text and use the title of the topic as a link For example if you are referring your readers to an accessibility article you will link Instead of Read More use Understanding WCAG Guidelines or any other name that is the title of the article or that best describes that link This is also good for SEO as it helps the search bots understand your links and gives your page a higher ranking Caption videosWhen you use videos endeavour to add captions to your videos This is a perfect case for accessibility as it will benefit both people with hearing impairments and people who are in a noisy place or even people who do not understand your accent Add a transcriptEndeavour to add transcripts as an alternative when you make videos or audio For people who cannot perceive the videos or audio use the transcripts Use proper headingsWhen creating content strive to use headings when necessary So assistive technologies would read something meaningful from your content Use h for the topic and h for subtitles to convey the meaning of the content when they are being read Run accessibility tests on pagesThere are accessibility tools some of which I mentioned above that you could use to run tests on your website to determine how compliant it is with accessibility Do not use small fontsWhen you use small fonts on your website older people and people who can see large fonts struggle to see The best option should be to use the fonts recommended by WCAG which are sizes Create accessible tables and add labels to formsAdd a proper description to your tables when you create them or if possible use markdown This would help screen readers read the table and the content within it When creating forms that you expect your users to fill out add a proper description to your tables when you create them or if possible use markdown This would help screen readers read the table and the content within it When creating forms that you expect your users to fill Strive to add labels to forms so they will be descriptive for screen readers Use screenshots sparinglyDo not use screenshots to convey the meaning of your text Always use text to describe But if it is necessary to add a screenshot or you understand that having a screenshot would help visitors to your site better understand your content Then you could use screenshots ConclusionThat sums up the core concepts of web accessibility Web Accessibility has provided many benefits to everyone both disabled people and people who have barriers that limit them from using the web like everyone Making your website accessible goes a long way in improving the content on the web For more info on accessibility guidelines check Web Content
