Accessibility Testing – Totally Tooling Tips

It’s good. Did you get a haircut? I did a haircut new accent, new new new. Look. You feel it’s good! It’s good you’re, looking better than before. You feel better than before. You’re, not mad. I am NOT no hi, I’m Rob Dodson, I’m a developer advocate on the chrome team, sure Rob just just sell, sell yourself. I mean hello and also uh you’re selling stuff, also host a little show on the chrome Developers.

Youtube blog called alley cast world-renown. Is that what we’re calling it yes well world renowned, I see people around the world have renowned it. I think, okay, all right, believe what you want to believe, but today we’re going to be talking about accessibility, audit, Angley right. What is your workflow for that? Look? Like yeah, so over here on, my laptop I’ve got a site that I’ve been working on.

This is called lifestyle. It’s got some cool like hipster photos and stuff, like that people have styles of the accessible and famous all right yeah, and what I usually do when I’m you know working on improving the accessibility of a site is, I will use the new audits panel in chrome, Dev tools, which is very very nice if you go to create a new audit, you’ll, see that you’ve got like a number of options inside of there, so you could look at PW, anus, best practices, etc.

One of the topic areas is accessibility, so you can just go run, just an accessibility audit. If you don’t, you don’t feel like doing the other tests. Here’s one that I ran against the page and it’s doing pretty. Okay right. It’s got on anyone not so bad, but there’s definitely a few issues that we need to fix and in particular one that I see a lot is, is color contrast, so you’ve got your your your foreground text.

Maybe is a little too light on the background. Color one of the nice things that we can do with the audits panel is we can actually dive in and we can see which elements specifically have failing contrast. So here I can see that I’ve got this like product card price element and if I click on that and stretch this out a little bit, you can see. It’ll take me over to my elements panel and I can actually scroll in to view the actual element that is failing just this price right, y’all, nice and it already selects the domnode for you, that’s cool, yeah, and so one of the things that’s really helpful.

Is you know really this is this? Allow me to sort of quickly identify this node, but one of the things we’re working on, which is over here in Chrome, Canary right now, is actually a color picker. That will make it a little bit easier for you to fix those contrast issues. So if you’re in something like Chrome Canary, you can go into Chrome, colon, slash, slash flags, you can look for the word: developer tools, experiments, oh you’re, in flags and experiments.

You look like to live dangerously, oh yeah, oh yeah, so dangerously, so we enable the developer tools, experiments right. We step into the future, it’ll refresh our browser for us. We can go back over here pop up in as the dev tools click on this little Settings. Menu good, where it says experiments da da and here we can see, we’ve got accessible the inspection as well as color contrast ratio line.

So let’s see what that does so we’ll go, find that same node. That was giving us problems over here. Inspect it and then we can see in our Styles panel I got a little color sread and click on that and you’ll see that there’s this little line inside of my color palettes. This is actually a sea mmmmm-hmm. This was actually telling us like. Where are our colors needs to be in order to have sufficient color contrast? So, since we’re above the line, we get this little warning that says, we’ve got a little contrast.

I happen to know that this is not like the final look for this piece of UI. It’s still being iterated on, but it’ll be something like this, where you’ve got a line and you can sort of tell which side is the good side of the bad side. So I can actually just drag this below the line. That warning goes away. You can see over here. It’s also like updating my element live in the document and it’ll sort of tell me what the good color contrast ratio is.

So I can just grab that value right off here and then go back and just fix it in my CSS. That’s pretty neat, so I was trying this out the other week and something that occurred to me was that you know if, if you use a developer, realize that the contrast is a little bit off, do you need to go back to your designers at that point, And say: well, is this okay for our brand and thing is that’s when they should be factored in earlier on in the process I ideal.

Yeah like this is there’s, there’s definitely other design tools out. There there’s, I think, there’s plug-ins for sketch, and things like that, which will also help you look at the color contrast for your designs and make sure things are not too low. Contrast, anytime, you can catch that earlier in the process, make sure all the designers are on board and all the stakeholders are on board and and that sort of like makes it easier when those things come downstream for folks to implement it, and it doesn’t kind of, Like a contentious issue or anything cool, that’s that’s awesome.

The house audit also had some other accessibility stuff in there as well right. So it had contrast. No, I was highlighting all the tributes to alt attributes, yep yep, so yeah. If we go back to that report, let’s see here so yeah a few of the things that that this site was failing. It’s missing some alt attributes. We’ve got form elements that don’t have associated labels: the big problem there is you land on a control, and maybe it says that it’s a button, but it doesn’t tell you what kind of button right is it the you know, sin my social security number to hackers Button, I don’t want to click that button right.

I want to make sure that I’m clicking the right kind of controls. I know what I’m interacting with we’ve got over. I think 32 tests, or maybe even over 35 tests in in the lighthouse accessibility checker here and under the hood. These tests are all based on a library called axe core which is made by some folks at a DQ so yeah. We we work at the axe, core library we leverage to the test from inside of it and we sort of integrated into dev tools.

You can hop around and inspect the notes. Real, quick, that’s awesome, so this is great again for locally checking on your accessibility issues. What about CI and continuously monitoring your accessibility? Is there a story for that too yeah? Absolutely so the the lighthouse library itself can be used as a standalone node module. So you can pull that into your CI process. If you want to do that or alternatively, you could use the axe core library that is powering these tests and you could use that standalone.

The the nice thing there is, you can sort of decide which accessibility tests you want to turn on or off, depending on sort of the criteria that you’re trying to meet very cool. So we’ve got lots of great tooling for accessibility, auditing. What about docks or education material? Yes, we have that as well. So if you go to developers.Google.Com/live Sunda mental, slash accessibility, we have a whole section there on getting started with accessibility for the web, and it also includes links to our Udacity course.

So that’s like a multi-week kind of hands-on experience where you actually like build stuff and read a bunch of articles and kind of get up to speed on accessibility, very cool yeah. I feel, like my lifestyle, is more accessible, already yeah cool yeah, thanks for having me today, yeah thanks for coming down awesome yeah people should check out ala cast: oh yeah, oh yeah,
