Accessibility is a second-class citizen for a lot of clients, therefore a lot of web agencies. In my two years working in one, only once was I tasked with a fully accessibility compliant site, and that was because it was government subsidized. Clients will gladly pay to move buttons and complain about a particular shade of blue or opacity transition speed, but god forbid we deliberately put any hours towards making the site accessible. We could try all we want to talk them in, they were the ones who paid in the end, and most of them just don't give a crap.

Most of our devs were pretty thorough about doing the most they could in the given time frames anyway, but it pretty much never was made a priority.

Also, conspiracy theory, contract development has a bit of a moral hazard problem when it comes to these sorts of issues.

On one side, we have the option that helps guard clients against accessibility issues and any problems that they might (though not necessarily will) engender, and is likely to be more maintainable in the long run. But it would also require fewer billable hours to build. And it's not what the client asked for in the first place, so there's the risk of burning social capital in trying to even suggest it.

Alternatively, you can get paid more money to supply the client with more immediate gratification.

Engineer isn't a unilaterally protected title here.

I took a different interpretation than your first conclusion there.

It sounds like you can call yourself an engineer all you like—particularly with relation to software. There appear to be no hard requirements.

However if you want to bill yourself as a Software Engineer and work as a Professional Engineer (the protected title in Canada) then you must have your P.Eng.

Similarly: A Software or IT Architect isn't required to be certified by the CACB. Nor does a Web Designer need to be a member of the GDC.

So— all Professional Engineers could bill themselves as Software Engineers (situation providing), but not all Software Engineers can work as Professional Engineers.

This isn't actually that non-sensical when you consider how being a PE works in other disciplines. You're legally responsible for reviewing and approving design documents, but you won't be doing all the work by yourself. You'll have a team reporting to you, and you sign off on their work. In the case of software, you don't necessarily need to be a programmer to review the design and high-level aspects of a program.

Well, there's a difference between "doctor" and putting "MD" after your name just like there's a different between "engineer" and a "PE".

I'd question if anybody really gives a damn if a software developer is certified with some feel-good namesake. Most software just isn't as serious as needing legal counsel or medical expertise.

Also, many of the roads I can think of where we do arrive at a place where people care about some certification are pretty terrifying.

>Most software just isn't as serious as needing legal counsel or medical expertise.

Most legal counsel and medical expertise isn't that serious either. Ask your family doctor how many patients they have every day who come in only to be diagnosed with the common cold, something anyone's grandma could diagnose over the phone and treat with a microwaved can of soup. But when it is serious, you don't want grandma doing your appendix surgery. You want a licensed and trained doctor.

For every one slippery slope argument, there's five "it's not that slippery" counter arguments. You don't need a medical license to buy over-the-counter painkillers, so why would you need a software license to build your own software? You don't need to be a bar-certified lawyer to write your own contracts, so why would you need to be a certified software developer to make a website?

Heck, take plumbers for an example: there are certified, bonded, and insured plumbers. There are plumbers who are not. You can choose a non-certified plumber, but most people would choose the certified plumber instead. If you don't need a certified software engineer, you're not going to pay the premium they would charge with no guarantee of quality. In this world, networking is king and if you don't know someone, you're screwed. If you need certified software, you'd hire certified software engineers and pay the premium and know you at least got someone who has passed their certifications and if they do poor quality work can have their certification revoked.

Considering poorly built software can bankrupt someone, publicly embarrass someone, and can even kill someone, the fact that anyone willing to lie on their resume can build it is scary. You can be reasonably assured that the surgeon operating on you is quality and there are ramifications if they are not. Are you sure that the person who wrote the code for your car's anti-lock brakes or airbags are held to similar standards?

Native elements work if your design spec is flexible and aims to look natural on every browser and platform. If you have a rigid design they aren't as useful.

Wouldn't be the end of the world if browsers actually exposed all of the relevant styling, but it does help to try and make flexible designs. HTML primitives make it a lot easier to reach accessibility spec.

Using built-in html primitives seems like such a good idea in theory, but when you have requirements that dictate a certain layout, or behavior on those elements you discover that some things you can't do, others you can only do in certain way, maybe in some browsers. Latest example of this is native input type=date: I want to use it every time I am tasked with making something that has date input, not once did it offer flexibility to meet the requirements (you can't format date, I don't think there is a way to hide clear button on ff, no duration input, etc...).

That was the great lie of the 2000s. It was oft repeated, but almost never adhered to. CSS Zen Garden was cool, but the typical attempt at "separating content from presentation" almost universally resulted in a div soup that was even worse than table layouts. If a div exists only to hang a class off it, so that it can be targeted in CSS, it's a part of layout, not semantic/information structure.

In a perfect world, in which most websites were not actively user-hostile, we could have separation of layout from content. It would include relinquishing control over rendering back to the users. It would require to stop obsessing so much over colors and layouts and custom controls. The very concept is anathema to the modern web, though.

Thanks, I've always thought this intuitively but never seen it written out.

Just as any academic theory hitting the reality through actual implementation, the theory should be more of a guiding force instead of a rigid structure to follow.

Much like how the military learned to plan battles (No battle plan ever survives contact with the enemy - Helmuth von Moltke the Elder) by giving troops higher-level objectives, rather than planning every single step of the attack, such as exactly where they should walk and hide, and expecting them to follow it to a T.

The problem is that, yes, this is the ideal, but when the ideal ran up against the real world usage of these tools, two things happened, one inevitable and the other just a bad choice:

1) a small, extremely vocal group of devs kept reminding us this while the rest of us used the standards "wrong" and did fancy layouts and things,

2) seeing how most of the world used the tools we had, the standards folks didn't give us good layout tools or application development tools, they gave us CSS and it took browser vendors like Microsoft to give us XHR.

Oh what I'd give for the standards folks to have taken some time to look at the world being built around them, and then given us a better way to do that, instead of "HTML shouldn't be used for layout" for years.

I feel like, had things gone in a different direction, web development now would be as easy as VB/Delphi/Lazarus (hell, even tcl/tk) once made desktop app development. Instead, we get the soup of languages, build tools, and the confusing mess of modern web dev.

There's no reason to not use CSS Grid, except for not knowing it well enough — and there's no reason not to learn it.

Of those, only IE11 is relevant, as it's a desktop browser, on wider and taller viewports.

Most of these browsers are mobile browsers on devices with narrow viewports, so even the default `display: block` fallback may be sufficient. If you have margins/paddings/widths etc which only make sense in the CSS Grid version, you can set these properties inside an `@supports` query https://developer.mozilla.org/en-US/docs/Web/CSS/@supports

For IE11, it's a choice of presenting visitors with a slightly worse layout, to match the browser (https://philipnewcomer.net/2014/04/target-internet-explorer-... or, if you use Sass or PostCSS, using mixins that output CSS Grid properties with Flexbox as fallback.

Its bugs are well-documented, and most have workarounds https://github.com/philipwalton/flexbugs. Even inline-block can serve as a fallback, if you can avoid whitespace around tags in the markup (https://css-tricks.com/fighting-the-space-between-inline-blo...)

A reasonable fallback doesn't need to match CSS Grid exactly. The whole point of media queries and responsive web design is that the website won't look exactly the same on all devices; it will look and work as good as it needs to look in that specific device.

My last workplace's policy was to fully support the last couple version of Edge, Firefox and Chrome, but for IE11, it was "it won't be utterly unusable".

This is basic HTML5 literacy. At the end of the day the new HTML5 and CSS features do not fit into out dated work practices and the excuses that go with it. Web content creators and developers should be familiar with all of this stuff and not kidding themselves that the 'sea of divs is the way to go because we do really important projects and need to have polyfills back to IE6'.

Not using the new tags and not using CSS grid is a bit like only eating fast food and no longer knowing how to use a knife and fork. When I look at div soup I know that the team behind the page have not got it yet. None of the div soup HTML is maintainable. It is dated. So any 'wow you can use the details/summary' article comes across to me as 'wow, you have learned to wipe your own nose!' This whole industry needs to get to grips with the lingua franca of the web, focus on document structure, use the stuff that works in evergreen browsers and move away from big up front visual design made into div soup to content driven design. It is that simple and excuses are pathetic.

Does Safari on iOS need to support this feature? Because isn't the entire idea of smooth scrolling to implement the scrolling that was ALREADY natively implemented on iOS?

Basically, while Safari might not "support" this feature, they already force their version of smooth scrolling on every site inside their browser.

On Safari for iOS or MacOS, you already get smooth scrolling no matter what. So they might not support the spec, but you still get it no matter what.

The only explanation I have for IE/Edge is that it is IE/Edge, and no one really expects much from those browsers anymore regardless. If I had a nickle for everytime someone told me "IE doesnt support that", then I wouldn't need a day job.

Lastly, this isn't a critical site feature in most cases. If an IE user uses your site without smooth scrolling, will it really impact their experience in any way? Probably not. So this is an example when you can safely use this feature, the browsers that support it will offer nice smooth scrolling, and the ones that don't will offer the same experience that those browser users are already used to.

The smooth scrolling set by the "scroll-behavior" is not the same as the user initiated scrolling in iOS. It is scrolling behavior when triggered by a navigation API [0].

If you go to the website in OP and click the table of contents in Chrome and then Safari, you'll see the difference.

Yep looks like it affects `scrollTo()` and `scrollIntoView()`, along with in-page navigation.

Crazy how they don't let you use a curve to define your own timing.

It's smooth scrolling when triggered by an action such as a fragment link or a JavaScript API, it's not referring to manual scrolling (eg scroll wheel, touch swipe).

Even if they did, those browsers use the safari rendering engine under the hood, so they'd have the same issue.

Why would you want to force smooth scrolling in the first place? It's a browser setting (at least in Firefox) and it should stay that way.

reply

[–] jacurtis link

I agree, I don't think this is a feature that web designers should worry about. How I scroll is something that should be set on the browser level.

This is sort of like a web designer writing CSS to redesign my browser tabs while I visit their site. This isn't their job.

Plus, on Mac devices with trackpads, the system OS already adds a smooth scrolling to all actions we do. So when we visit these sites that add smooth scrolling with Javascript it can cause us to go insane. Because scrolling becomes insanely sensitive, with 2-3 inputs trying to control scrolling behavior (the OS, the browser, and now JS). The system is adding its own acceleration and deceleration, and then javascript is sitting on top of that trying to interpret these forces and add their own multiplier on top of those. I have visited sites that have JS implemented smooth scrolling that is so sensitive, that I can't even barely touch the trackpad without scrolling down an entire page length.

Whoever wants to force it will otherwise do so with JS. With CSS at least you can override it with a client stylesheet.

Is smooth scrolling really a feature you need in every browser you support?

reply

[–] jypepin link

well, just like any other features, assuming there is a good reason for you to implement that feature, you want most browsers to support it.

I doubt Firefox or Chrome on iOS support scroll-behavior anyway, since Apple forces them to use WebKit.

This is because the CSS spec is consciously written so that you only never need to look forward when parsing the DOM. For the same reason there is no follow sibling selector, only previous sibling (`~`)

This is a major performance factor, since it means all layout can be done in one pass. If the proposed selector were added. CSS layout would have unbounded complexity.

Here’s a thing I can’t do with CSS combinators, and I’ve always been curious why: apply rules to an element that contains any elements matching the criteria. E.g. (hypothetical Regex-like syntax):

    (tr) > td img.emoji { padding-bottom: 1em; }
...would take any table row containing a cell with an image in it, and pad the table row itself a bit more, so as to balance out the image which is slightly larger than the text height.

The lack of this feature doesn’t bother me so much when actually developing for the web, but so many web scraping libraries offer CSS-selector accessors as an alternative to/replacement for XPath accessors, and when using these libraries, the need to grab the container element of the thing tagged with something (where the container itself has no distinguishing features other than having such a child) always results in inefficient spaghetti compared to what could potentially be a very simple selector.

Anyone know why we don’t have these? Something to do with the cost of rescans on DOM changes, maybe?

One thing I think is missing from the current html spec is having a src attribute on select tags. Would be nice to be able to not have to define the options directly on a page and instead serve them up dynamically. Not a big problem off course, but it seems like something that is missing.

In my narrow mental model I've always heard the claim that HTML and CSS is the purest form of document representation. A static site that can not get any more lean then that. And yet after removing the JavaScript (the source of all evil on the net) the site still can not handle the traffic and offers a 500 internal server error!!! Really? they can't serve static HTML on a site that is promoting static HTML features?
