Issue #414 (Vision, Frameworks, JS Utils, Uncats)
Practical, real world React examples of Intersection Observer.
• Each example is available as a React component
• Easy to understand
• Reusable patterns
In case you missed it, last year Chrome's DevTools added a new feature that comes in handy for some very specific accessibility testing: The ability to emulate vision deficiencies to mimic how users with color blindness or blurred vision see your pages.
It's not the easiest feature to find but once you find it, you'll notice some other useful testing features in the same area of DevTools. The "Emulate vision deficiencies" option is found by doing the following:
- Open DevTools (F12) on any web page
- Open the Console Drawer by hitting ESC or selecting "Show console drawer" inside the three-dot option menu (top right of DevTools)
- Inside the Console Drawer, choose "Rendering" from the three-dot option menu (top left of Console Drawer)
- Scroll down to "Emulate vision deficiencies" in the Rendering sub-panel
As you can see in the screenshot, you can choose from 4 types of vision deficiencies to emulate:
- Blurred vision
- Protanopia (difficulty with perceiving red)
- Deuteranopia (difficulty with perceiving green)
- Tritanopia (difficulty with perceiving blue)
- Achromatopsia (absence of color vision, seeing only grays)
If you try it out on a color rich page, you'll see the differences. I've produced an image collage below demonstrating each of these emulations using this image from Unsplash
A nice feature to keep in mind to add to your accessibility toolbox and workflow. For a little more detail on this subject, see Addy Osmani's post on the subject from last year.
