Great!
Hi, great demostration, why my firefox do not show the defficiency color simulator? is possible when the imac is some old? i see accessibility inspector, but color blindness simulator can't see
Thanks a lot. Great stuff.
Is the Color Vision Deficiency Simulator (color blindness simulator) not showing up on your computer? At 6:40 I explain why, and how you can turn it on. Be sure to watch that part.
Epic! Can’t wait to see more and I’m glad accessibility is starting to finally get more awareness.
Fancy!
Hi Jen. Thank you for the good content in mv. But I world like to ask another question. When Firefox Will supports select <option> css attributes. Now, if I want customize select and option, I should use javascript.
This is what I needed! Really practical new features in Firefox :)!
5:21 According to this article, white text on colorful backgrounds can be an accessible combination even while failing to meet the contrast ratio. https://uxmovement.com/buttons/the-myths-of-color-contrast-accessibility/
Crazy good video 👌. Enjoyed it
I've been reading an interesting conversation https://github.com/w3c/wcag/issues/695 about the math behind the contrast ratio. the current formula `(L1 + 0.05)/(L2 + 0.05)` may change to `(L1 – L2)/(L1 + 0.1)` in the future. As a developer, should I care about this change? I'm developing a website that has the infamous orange as a primary color. I do want to meet WCAG 2.0 AA, but it's difficult to tweak the orange color on white background. With the possible change of formula in WCAG 3.0, some variants of orange can be accessible.
Stop with the double U CAG. It's WiCAG (like Wick AG). But thanks for the FF color contrast tool. Handy
So cool!
Thank you so much for these videos. Very informative. One suggestion for the thumbnail image – I like that I can see who's the representer in the video, but why don't you have one good image of yourself and keep uploading the same one? I think this makes it more consistent, and probably easier for you 🙂
