The Ultimate Guide to 508 Compliance

If you want to be certain you’re meeting the needs of everyone in your website audience, you must take steps to ensure your website is 508 compliant.

The compliance standards are set by Section 508 of the Rehabilitation Act of 1973 that requires federal agencies to provide software and website accessibility to anyone with disabilities.

When your website is 508 compliant, it means it is accessible to all users. Your website is compatible with assistive technology, such as screen readers.

The following agencies that receive federal funding are required to be 508 compliant:

Even if you do not fall into one of these categories, it is wise to voluntarily choose to be 508 compliant. Not doing so increases the risk that someone in your customer base will not be able to use your website or any of the features it offers.

My daughter was born blind and faces challenges using the web and technology every single day. It’s not fair to her, and it’s not legal. I am part of the Web Content Accessibility Guidelines (WCAG) group with the World Wide Web Consortium (W3C) and am an advocate for accessibility. If you feel you web site is not compliant and want immediate help you can hire SEO Inc to make sure you are following best practices for Web Site Accessibility!

That’s why I want to talk to you about how you can check to see if your current website meets 508 compliance guidelines, and if you discover that it does not, what you can do to fix it. But before we get into that, let’s talk about the bigger picture for a second.

Many companies don’t take action unless they believe it’s going to provide a return on their investment. 508 compliance is one of those things that often gets overlooked simply because the ROI is hard to see.

The truth is only a small percentage of your web visitors will be blind. However, many of them will be low vision. Even more of them will be using small screens in bright environments. By following guidelines for people with low vision, you are addressing the fact that everyone is visually impaired sometimes.

Only a small percentage of your visitors will be dealing with dyslexia. But even the most intelligent of people run into text they don’t understand sometimes. By following guidelines set forth for dyslexic readers, your non-dyslexic readers will thank you. Think about the person who standing in an airport line at midnight with a small child on their shoulder and a phone in the other hand trying to read instructions on where they can find the rental car kiosk. They will appreciate your efforts just as much as dyslexic user.

Only a small portion of your visitors are dealing with physical disabilities. But everyone has run into buttons and sliders that are so small it takes multiple attempts to click them. And everyone has run into a website that doesn’t work well with touch screen devices. If you take the time to design your website for those with physical disabilities, you’ll create websites that are easier for everyone to use.

How to Make Your Website 508 Compliant

Blindness and Low-Vision

For every non-text element, you should provide a text equivalent via “alt”, “longdesc” in the site’s HTML code, or in element content. In-element content should place text on the image, or use a caption below the image to describe what the non-text element is, for people who are blind or low-vision.

Be sure to provide transcripts for video and structure content using HTML5. Build the website for keyboard use only. Write descriptive links and headings. Do not force mouse or screen use or rely on text size and placement for structure. Design your content as though the person is using a screen reader to navigate your website.

Make sure to use good color contrast and a readable font size. Use a combination of color, shapes, and text while following a linear and logical layout. Ensure buttons and notifications are included in context. Make sure that text flows and remains visible when your text is magnified to 200%.

Do not rely on color as a differentiating factor. While the majority of people are familiar with color coded alerts and traffic lights, those who are colorblind, particularly suffering from red and green color blindness may not be able to tell the difference.

Instead of relying on red and green to indicate stop and go or good and bad, rely on another system such as check marks and Xs to indicate availability. You can make the check marks green and the Xs red to enhance the overall design for users, but the added layer ensures that even those who are color blind will still be able to interpret the information correctly.
