For most sites, the content is what matters more than anything. In this video, learn what characteristics prevent your content from being accessible.
- [Instructor] Earlier in the course I introduced the concept of accessible content, and referenced several ways in which you can make choices that influence the accessibility of your original copy. It's time to delve deeper on these topics. To start, we need to talk about the words you choose. There are many ways in which word choice can have an immediate impact on accessibility. Within the text itself, you'll mostly be thinking about percievability and understandibility from the four principles of accessibility. If you write in the graphic on the left, that instruction isn't as clear as it may seem. For a screen reader there is no right or left. If this page is viewed on a mobile device, that graphic may above or below the text. When the site is redesigned, perhaps the text will stay the same, but the referenced graphic might appear somewhere new. Instead of using positional references, provide instructions that are unambiguous, or use a link that targets the image. Clearly labeling images can help. If you need two images to be compared, labeling them as image one and image two will help clarify this ambiguity. Color maybe used in your text in a similar way. Writing click on the orange button, has clear risks. Visitors who are colorblind or using a screen reader can't tell which button is orange. In bright sunlight, colors may be impossible to distinguish. And if the site is redesigned, the orange button may not be orange. Other content can introduce problems with understandability. If you use abbreviations and acronyms there is written information present, but if the user doesn't know the abbreviation, it's not understandable. You should write out the meaning of any abbreviation the first time it appears in the content. A similar problem occurs if you use terms or phrases that are in another language. When a screen reader is in use, the language of the interjected content needs to be defined. Without markup that indicates the new language, a screen reader will use the same pronunciation rules as the previous language. It's not just the use of assisted technology that is affected by text choices. While these examples all impact people using specific technology, some choices will affect people because of their own perceptions. Cognitive impairments and learning disabilities are classes of disability that affect how people perceive and absorb information. Some of these have an intellectual component, but many do not and need to be considered no matter your expected audience. Unnecessarily complex language is one area to watch for. Sometimes complexity is essential. When writing on quantum mechanics simple language may not be an option, but if you're writing instructions for using a transit ticketing machine, the text should be comprehensible by anybody who uses public transit, a much broader group. The visual appearance of your writing impacts people with reading related disabilities. Dyslexia and related disorders, attention deficit-hyperactivity disorder, and processing deficits are all affected by how you structure and style your content. We'll dive into content structure later in the course, but style also affects many groups of users. Take something as simple as text alignment. The use of text that's either center-aligned or fully justified, can cause unique problems. Center-alignment is particularly hard on people with low vision. Because the use of significantly enlarged text usually means that your screen only shows a couple of words at a time, the use of center-alignment creates challenges in moving from one line to the next as the user hunts for the beginning of the next line. Fully justified text can create significant problems for people with Dyslexia. The uneven spaces between words that run all the way down the page, create an effect called Rivers of White, in which these channels of white give an impression of motion that draws away from the text itself. Having content that is easy to read, easy to follow, and supplies all the information needed to understand it, will help make every page better for all of your users. Accessible content is usually better everybody.
