The icon controls also provided a tooltip (keyboard accessible of course) to clarify what the icon is for. Icon fonts were implemented for these types of actions in the rewrite of Easy Chirp. There are also icons for actions regarding the tweet author such as viewing their timeline, sending a direct message, and viewing their lists. Each tweet provides a graphical icon that can be activated to perform an action on that tweet such as favorite, re-tweet, and quote tweet. It was rewritten in 2013 with the help of Andrew Woods and a successful Kickstarter campaign.Īs expected, the Easy Chirp interface displays a timeline of tweets. Here’s an HTML example of an accessible linked SVG icon (an aria-label in the A element could also be used and is often a more pragmatic solution): Įasy Chirp is a robust and accessible web-based Twitter application that I first developed in 2009 (originally named Accessible Twitter). There are several other great resources on the topic such as the HTML slide deck Making SVG accessible by Léonie Watson. They can usually be made accessible depending on the use case but not always–see my SVG accessibility test page for details.

But because browsers often don’t pass pertinent information to the Accessibility API, SVG is still spotty for accessibility particularly for assistive technology such as screen readers. SVG icons can be multi-colored (whereas icon fonts are limited to one color), and they can be animated.īrowser support for rendering SVGs is very good. Since SVG icons are vector-based they scale beautifully, and even better than icon fonts since fonts are subject to anti-aliasing. Recently, the use of SVG for icons (and general usage of SVG) has become much more prevalent. But in addition, ARIA is used to hide the character used for the font icon from assistive technology (so a screen reader doesn’t literally read the special character which wouldn’t make sense).

Like sprites, CSS classes are used to create the visual icon with pseudo-content and to visually hide the alternative text. Also, Microsoft now provides two CSS media queries that can be used to explicitly enhance a design in High Contrast Mode-namely -ms-high-contrast media and -ms-high-contrast-adjust.īelow is an HTML example of an accessible linked font icon.

Note: In Windows 10 (with Microsoft Edge), High Contrast Mode no longer removes background images. And since icon fonts aren’t used as background images like sprites, they are not removed with Windows High Contrast Mode. Also, since a font icon is text, CSS can easily be applied to adjust the size and change the color. A major advantage of icon fonts is they scale very nicely they increase in size with much better quality than raster images. Then came icon fonts, somewhere around 2012. CSS classes are used to create the visual icon with pseudo-content (:before or :after) and to visually hide the alternative text. Here’s an HTML example of an accessible linked sprite icon.

Also, many services that auto-generated sprites were not outputting code that supported accessibility. Sprites with some effort can be made mostly accessible, but there were issues with background images being removed in Windows High Contrast Mode (HCM). A sprite is a single graphic file with multiple images embedded within it CSS background and positioning is used to display a single image at a time. A sprite requires a smaller total file size and less HTTP requests than using numerous independent graphic files. In the late 2000s, CSS sprites became a popular method for displaying icons and other images, mostly for performance reasons. (Notice that the alt text conveys the target of the link more than the image itself.) It simply places the alternative text in the alt attribute. Here’s an HTML example of an accessible linked image. Brief History of Web Icon Techniques ImagesĪ classic in-line image is a very accessible and robust method for displaying an icon. Hyperlinked icons will be used in most code examples for purposes of consistency and also because that’s how the web app (Easy Chirp) uses them in the case study below. Let’s discuss a brief history of web icons, advantages and disadvantages of several development solutions, and how a particular web app uses them. There are many maintenance, performance, and accessibility considerations when designing and developing icons-especially for the web-that makes something seemingly simple rather complex. In the digital world, graphical icons are used prominently-play buttons, social media links, warning indicators, and on and on.
