Atext and accessibility8/14/2023 ![]() In addition, text that’s inside an image isn’t translatable into different languages, selectable for copy/paste, or resizable without degrading its quality. One disadvantage here is that screen readers will, in some contexts, read the alternative text with "graphic" appended, and you might not want the user to know that the text is really an image. In a WYSIWYG editor, it is possible to upload an image of some text (let's say, "delicious pancakes") and insert it into the page with alternative text that matches the text exactly: If you do this, you'll need to provide that same text as the image’s text alternative so that screen-reader users can access the text. Only in extreme circumstances, such as when a logo is used, should you provide an image of text rather than text. If you feel that you need text that deviates from the style, formatting options provided by online content editors should allow you to update the style for that text. If you use an online content editor to write content, the styling will happen automatically. So wherever possible, use text along with CSS to apply styling (such as color, typeface, or size). Some people with reading difficulties or visual impairments need to customize the display of text to make it easier to read. When text is presented as an image of text, that limits their ability to change the appearance of that text. While accessibility requirements do not mandate use of specific fonts, be aware that people who have online reading difficulties benefit from body text set using a clear, consistently formed and balanced sans-serif font.Ĭareful styling can help overcome these issues in HTML documents and in online documents that are published in other formats, such as Word or PDF, while also providing flexibility for people who need to customize text appearance. In this case, it is not set at all, meaning it can easily grow too large on wider viewports. The width of a paragraph is called the "measure." Measures that are too wide make it difficult for readers to scan back to find the start of the following line. Justified text can produce unevenly enlarged spaces between certain words, sometimes known as "rivers". Justified text can produce readability issues for people with dyslexia and other conditions that affect reading and comprehension. A value of 1.3 to 1.5 is optimal, depending on the font. There needs to be some space (although not too much!) between each run of text, to separate them. The line-height or "leading" is too tight at just 1. There are a number of things wrong with this example: For people who do need to customize display of text to make it easier to read, it's important to support this customization rather than forcing them to read the text the way you specify.įor the most part, this means applying typesetting best practices, which predate the web. Paragraphs of text are a fundamental core of web content, so it's important to display them in a fashion that is optimally readable to the majority of your audience without requiring them to change their display settings.
