High website accessibility -

Access to information and communications technologies, including the Web, is defined as a basic human right in the United Nations Convention on the Rights of Persons with Disabilities UN CRPD.

The Web offers the possibility of unprecedented access to information and interaction for many people with disabilities. That is, the accessibility barriers to print, audio, and visual media can be much more easily overcome through web technologies.

There is also a strong business case for accessibility. As shown in the previous section, accessible design improves overall user experience and satisfaction, especially in a variety of situations, across different devices, and for older users.

Accessibility can enhance your brand, drive innovation, and extend your market reach. Web accessibility depends on several components working together, including web technologies, web browsers and other "user agents", authoring tools, and websites.

The W3C Web Accessibility Initiative WAI develops technical specifications, guidelines, techniques, and supporting resources that describe accessibility solutions. These are considered international standards for web accessibility; for example, WCAG 2. Many aspects of accessibility are fairly easy to understand and implement.

Some accessibility solutions are more complex and take more knowledge to implement. When developing or redesigning a website, evaluate accessibility early and throughout the development process to identify accessibility problems early, when it is easier to address them.

Simple steps, such as changing settings in a browser, can help you evaluate some aspects of accessibility. Text alternatives are used by people who do not see the image, such as people who are blind and use screen readers to hear the alt text read out loud.

To be useful, the text should be short and descriptive. Video captions. Videos can be made accessible by including synchronized captions that are accurate and identify any speakers in the video. Online forms. Labels, keyboard access, and clear instructions are important for forms to be accessible.

Labels allow people who are blind and using screen readers to understand what to do with each form field, such as by explaining what information goes in each box of a job application form.

It is also important to make sure that people who are using screen readers are automatically informed when they enter a form field incorrectly. This includes clearly identifying what the error is and how to resolve it such as an automatic alert telling the user that a date was entered in the wrong format.

Text size and zoom capability. Keyboard and mouse navigation. Keyboard access means users with disabilities can navigate web content using keystrokes, rather than a mouse.

Checking for accessibility. Automated accessibility checkers and overlays that identify or fix problems with your website can be helpful tools, but like other automated tools such as spelling or grammar checkers, they need to be used carefully.

Also, a report that includes a few errors does not necessarily mean there are accessibility barriers. Pairing a manual check of a website with the use of automated checkers can give you a better sense of the accessibility of your website.

Reporting accessibility issues. Websites that provide a way for the public to report accessibility problems allow website owners to fix accessibility issues. This is not a complete list of things to consider.

There are many existing resources to help businesses and state and local governments with making websites accessible to people with disabilities, some of which are included at the end of this document.

When Congress enacted the ADA in , it intended for the ADA to keep pace with the rapidly changing technology of our times. Since , the Department of Justice has consistently taken the position that the ADA applies to web content.

As the sample cases below show, the Department is committed to using its enforcement authority to ensure website accessibility for people with disabilities and to ensure that the goods, services, programs, and activities that businesses and state and local governments make available to the public are accessible.

See 42 U. Back to text. You will be automatically redirected to a:. But, some visual designs do not allow for descriptive link text. One strategy for dealing with such designs is to include extra text within a span inside the link.

Developers can use CSS to hide the extra text visually but still expose it to screen readers. Developers should use care when providing such screen reader-only text. The following techniques will hide content from screen readers altogether and should be avoided when providing screen reader-only content:.

Besides the hidden link text approach discussed above, ARIA provides HTML attributes developers may want to consider: aria-describedby, aria-label, and aria-labelledby. The aria-describedby attribute provides extra text for a screen reader besides the link text.

To give a link an ARIA description, first give the descriptive text an id attribute. A screen reader will first read the link text, then the description. For example:. Developers can also create ARIA labels the using aria-label and aria-labelledby attributes.

Assistive technology considers an ARIA description to be in addition to the link text. But, assistive technology considers an ARIA label to replace the link text. For that reason, links with ARIA labels may create a worse experience for speech recognition software users.

If the ARIA label does not match the link text at least in part, speech recognition software may not work as a user expects.

To use the aria-label attribute on a link, set the aria-label equal to the label directly. To use the aria-labelledby attribute on a link, first provide some other text an ID attribute. It is keyboard focusable, and screen reader will announce the link as a link.

By default, the hover mouse cursor style is set to a pointer, instead of the default arrow. But, these kinds of emulated links need care. Developers wishing to emulate links must include the following:.

Use unique link text where possible. Speech recognition software users may have a bad experience with duplicated link text. It is OK to link a full sentence, but avoid longer. Use judgment when linking full URLs.

When linking a URL, consider users who must speak it out loud and who must listen to a screen reader announce it. Image Links In general, content editors should avoid using images as links. Adjacent Links Pages should not present more than one link to the same destination next to each other.

Designing Links Non-Color Indicators Giving links a different color from the surrounding text is common on the web. While the WCAG guidelines allow for this, the requirements are extremely stringent: A non-color indicator, such as an underline, must be present on hover The contrast ratio between the surrounding text and the background must be at least 4.
