Most people know about semantic HTML, but when it comes to CSS, things are a little more wishy-washy most of the time. Rather than relying on arbitrary class names, we can use different semantic selectors though!

A lot of questions and comments about the performance of attribute selectors, so I did a quick test. In my test, a class selector with 10,000 matches was ~0.3ms faster than an attribute selector with 10,000 matches. In other words, you've got bigger things to worry about (screenshot is here: twitter.com/KevinJPowell/status/1623403310785896455 ) They *can* beslower, slower if you use things like $= or *=, but even then, it's not *that* bad!

Nice. Is this only in Edge? or is it just well hidden in Chrome via a dev panel command? (need to check this later) We use tons of attribute selectors, data-foo, aria-bla, and our own. Also many [id=] to avoid specificity troubles and several ~= for data attributes with string lists. After all, html5 doesn't care, CSS doesn't either, and for JS-DOM it's all attributes or dataset. I'd assume the *= |= and ~= selectors could be a tad microsecond slower. They have to match against a whole list of items, whereas ^= and $= only look at the start/end of it. Probably boils down to the browser's regex performance. 🤷🏻‍♂

The prefered way to do it is to not link to current page from current page, and because the tag will be missing in that case, you can also do automatic styling of the current page menu item without using any aria or other, because you inherit the style from the instead. In other words, it should be dealt with on the server side, not client side, if possible.

As I'm fortunate enough to not require any accessibility features, it's easy to forget that people do require them I once read that accessibility isn't an additional step, if accessibility is missing you've missed a step, and so I do want to keep that mindset up.

It's best to keep the aria at a minimum, or at least not use if you do not fully understand it, and test them too in a screen reader, because using them wrongly could lead to unknown results. Chrome has a screen reader extention, but I don't know how good it is. Linking to current page from current page does not make sense, and it should really be dealt with on the server side, not client side, if possible. Don't send code which is not supposed to be used to the client.

I've started using that technique a while ago myself after facing a very complex HTML layout that had to be styled. It occured then to me that those aria attributes that have a state (e.g. aria-expanded="true") act like an if/else statement. After that realization, complex HTML pages have become super easy to develop

Thanks for this video and the links to the articles. I have always wondered why people were not relying on the attributes more (aria or data-) and used classes instead. The only argument I found was that class selectors were faster. But, for one, performance is not set in stone and the more people will use attributes, the more important it will be for browser developpers to optimize this, and also I was never sure that when your page is slow it would be because you used attribute selector instead of class selector. The fact that the page is smaller and the javascript simpler should have some weight too.

This quickly breaks down though if you have multiple styles of tab / button etc (Nav buttons for instance can be wildly different to form buttons), or how this would help when styling general divs. As you now have two different "naming" conventions you have to maintain.

I've been developing for over 14 years and while I rarely do frontend most of the time, whenever I do, giving sensible names to CSS classes is really hard (given we don't use tailwind CSS, though I'd argue there are ways to have this semantic CSS along with tailwind CSS). This definition makes things easier in terms of understanding what the hell is going on. Like if you have tabs, make that visible by using role or and aria-current or something! I do think though this can become increasingly harder if you are using UI frameworks, that don't pass on classes by default or encapsulate the rendering of a UI element.

For sure! I think I'd probably use custom properties.

Semantic css, specifically having descriptive class names, is what I'm nervous about giving up with a project that only uses TailwindCSS. When I read HTML I look at the class names more than anything else to know what I'm looking at. I'm interested in the benefits of Tailwind, especially when working with other people, but I so much prefer reading HTML with descriptive class names.
@RILCOMusic
@RILCOMusic Жыл бұрын
May I suggest using a blank class name as a semantic placeholder? Then you can use Tailwind to apply styling but you can still use the unstyled class names as a reference for what they structurally do.
@rand0mtv660
@rand0mtv660 Жыл бұрын
I think if you get into Tailwind and learn it, you'll just be able to piece together how something looks like just by reading those Tailwind classes. Also, if switching from project to project and they all use Tailwind, you'll be able to recognize styling just because classes are stanardized in Tailwind. You don't get that benefit with custom styling. Your point about descriptive class names is only valid if people on a project actually gave descriptive names to things and we know naming things is one of the hardest things in programming :D

Thanks for passing that info, i've been trying to implement that approch in my dev for some time .... because while trying to pass a11y to html, you often get some redundency: Some stuff .btn just tells us what it should look like because of its function (that is a button) so i'd trim it. Same thing with .btn-primary ... I mean .primary sure mean nothing and shouldn't be styled that way, but [role="button"].primary or [role="button"].red are workable, meaningfull and accessible! Maybe you might end up with larger CSS, but with smaller HTML.... so I feel that that pattern is kind of the anti-tailwind css :P
@QwDragon

With css variables you can style .primary to setup colors and .btn to apply them. You can even make it compatibile with tsx. Also I'm not sure that every role="button" should look like a button. Cancel button is often styled as a link.

I've heard advice not to style tag names (e.g. ``) and instead prefer to use classes. But that conflicts pretty strongly with semantic CSS, since following accessibility best practices means that you should use a tag rather than a role attribute when available (e.g. `` instead of `role="list"`). So you would then be forced to select something like `.list-widget > ul` instead of `.list-widget > [role="list"]` to comply with semantic CSS practices. What's your perspective on this? Is the advice to not style tag names generally valid but it just doesn't apply to semantic elements in particular, or is it just bad advice?

What's your take on using data-attributes for CSS? I'm thinking there's something to it, but I'm not sure what yet. Specificity is a little different than class names I know, but data-attributes can contain different types of data, and their selectors can be a little bit smarter, maybe? Is changing a class different than a data-attribute, performance wise? Of course, JavaScript knows about "classList" and data attributes are "dataset". Perhaps it makes programming them more intuitive, which could be beneficial?

Specificity is the same. But flexibility can be better. Dataattributes can contain only strings and nothing else. I've never seen performance problems due to selector unlike the styles themselves.

How are attribute selectors not well supported? Part of building something is building it correctly. You don't build a bridge without proper reinforcments because it won't look at nice. Might be a bit of an extreme example, but just because we don't like the "look" of all the extra attributes on something doesn't mean it shouldn't be there if that's the correct way to build something.

Interesting video as always, but I have a question. If you reference the role or the aria of an element with css, ¿Doesn't that raise the specificity of your style, thus creating overwrite problems? Greetings from Chile!

an attribute selector has the same specificity as a class selector, so it doesn't have to... I'd also argue if you're doing something like `.tab[aria-selected="true"] which does have higher specificty, that's probably fine anyway :)

@@KevinPowell I didn't knew they had the same specificity, that's awesome, thank you for taking the time to answer.

@@KevinPowell As a side note. < img /> _"Trailing slashes in void-element start tags do not mark the start tags as self-closing"_ ...is what I get from the validator. It means, you can use the trailing slash if you think it looks nice, but it serves no other purpose or function. The fun thing is, on MDN's page about img, they use both options, both with and without trailing slash. Seems like they are confused too. But it looks like the HTML standard is moving away from using the trailing slash (which is a left over from XHTML which I wonder if anyone uses anymore), and the first push in that direction is the validator info about it.

Realy interesting subject. Nevertheless I notice one point in your presentation that is "weired". The semantic was about the class current-page. And you convert it to an attribute aria-current="page". That's a small mistake: you should use aria-current-page="Home" (then About, Contact,... according to the current url) Thus, your css selector must be [aria-current-page] i.e. any current menu element (unless you need a specific color for each item) For your demonstration, using the class "current-page" or the attribute "aria-current-page" is semantically equivalent.

We need to use `aria-current="page"`, there is no such thing as aria-current-page. Aria attributes follow a standard, and in this case, the `aria-current` one is to let people know the link they are on is the current page, the same way we often style that link differently with CSS to visually indicate things. There is no `aria-current-page` attribute.

Instead of letting every a-tag have a class, maybe style it based on the wrapper instead as well using the semantic ul li a?

Isn't it kind of a return to styling elements which was always considering as a bad practice?
@KevinPowell
@KevinPowell Жыл бұрын
Only reason we don't style elements directly is element selectors tend to be too vague. If I need my paragraphs to have a specific style, I'm styling the p tag, and not giving them all a class 🤷‍♂️

I've had discussions in the past about semantic class names (note the subtle difference) but that was stupid. Per spec class names are meaningless to the browser so the question becomes semantic for who? And the answer is other developers. Part of writing good code is that other devs can understand it and class names are a way of communicating with your colleagues.
