HTML can do that?

After witnessing some awesome things CSS can do, it's time for HTML to come in the same spotlight! It's amazing that you can do so much with just ...

The only one not working in Safari is the dialog, all other examples work nicely. The autocomplete even surprised me because it shows the autocomplete suggestions in the keyboard!

Make sure you are in a recent iOS version and you are using the default keyboard.

Dialog only works in Chrome based browsers. Firefox doesn't support it without enabling an option.

If you've come across any such cool thing HTML is capable of, please mention below 😀

My preferred one. On desktop:

rendering of date picker in FF

On mobile:

rendering on Safari on iPhone

Source code:

<h1>Date picker</h1>

<label>Choose a date: <input type="date"></label>
Enter fullscreen mode Exit fullscreen mode

Nice, the datalist is one I'll have to definitely look at. The frontend team at my job is building out a new set of components for our apps, including various dropdown/filterable elements. Same with details.

Stephanie Handsteiner

I was thinking the same, although you'd still need some kind of JavaScript fallback for older browsers, even for the datalist one. Safari for example is supporting that since 12.1. (macOS) and 12.2. (iOS) only.

thankfully we only have to support latest FF, Chrome, and soon Edge. i'm ok with that.

Great post, shame some of these features are not supported on major browsers.
Don't forget to visit caniuse.com/ before attempting to implement one of these features.

Collapse
claudepache profile image
Claude Pache • Edited

But we can still use these today with progressive enhancements! 🙂

... but only after you have carefully tested nonsupporting browsers. ⚠️

The “dialog” example looks very bad on latest stable Safari (12.1):

(dialog mixed over content)

but that can be fixed with proper CSS (although I’ve tested it only superficially):

dialog {
    background: white;
    border: medium solid black;
    padding: 1em;
}
dialog:not([open]) {
      display: none !important;
}

At this point, I would still test IE and Edge before using it.

There's a polyfill for those, although Edge will arguably gain support as soon as it switches to Chromium.

I learned about datalist 1-2 years ago and it still blows my mind. I think it comes from many horrible years of fudging it with JS

Not sure if I'll ever encounter a use case for it, but deletion and insertion are pretty rad, didn't know that thing exists. 👍

However, I'd suggest adding text-decoration-skip-ink: none to the <ins> CSS, otherwise macOS font rendering will butcher some of the wavy underlines:

Screenshot of wavy underline below the word "begin", the underline is interrupted by the rather wide "g" glyph which looks inappropriate

With 5% worldwide market share (around 2% decrease since last year) and not getting any real updates for around 6 years, you might as well just show "upgrade your browser" page to the elderly people still using IE.

In my experience, it's not elderly people, it's corporations with locked down machines, which is why we'll probably need to wait a long time before it goes away entirely.

IE is moving to Chromium soon, so it will quickly get back in sync with modern browsers.

Collapse
karlkras profile image
Karl Krasnowsky

but there is (as far as I know) no mandate to force users to stop using current versions of IE. Heck, there are still companies using Windows 7. We'll see a small, but very vocal ie user base that refuse to give up this piece of trash for a long time yet.
Unless a company can take a stand that they will no longer support it (which I have proposed to my management), it will continue to be a thorn in our side for a long time.

Well, the dialog box will not work without JS, so it can't be considered pure HTML solution.

On the other hand, combining checkbox with some CSS, the same behavior can be implemented without JS at all.

Nice, I like the lightweight approach. However, there are certain limitations to the HTML-native components. As has already been pointed out, the dropdown doesn't play well with scrolling. If you use a HTML , then you have little control over the look of the dropdown in CSS. It's all about those small things... I believe browsers could do a better job with the native components and their HTML integration. Currently, web devs build the most absurd constructions to achieve things like a dropdown menu, and run into the weirdest corner cases with focus handling, overlay anchoring etc.

So many people talk about super power of web component. And look at this default elements. This is something sad, because lots of this elements is implement badly.

Datapicker? - has broken layout and design, there is no usefull attributes
Dialog - not woking in every browser, there is no usefull attributes
Dropdown - UX sux. I choose one element and when i open list another time, i will see only this element. No atributes for change this behavior

This is awesome! I've used the details element on a project we've worked on recently, we've ended up not using JS for anything because it wasn't needed and applying this element contributed towards this outcome. 😄

Is it fair to say that HTML can do dialogs? It's not only that there's JS involved. It's that you still have to position it. There is semantics value for accessibility though.

Collapse

You don't need css to actually make it work. Yes, JS is required to put the attribute but I think it's fair to say that html is doing all of the heavy lifting!

JS is NOT required for making dialogs! It is possible to make them in pure CSS:

What about the positioning? I think overlapping everything in the page is a key feature of a dialog, and I see there is positioning in the CSS.

How to handle dropdown with different data between value and text?
example :

<option value="GB">United Kingdom</option>
<option value="US">United States</option>
<option value="UM">United States Minor Outlying Islands</option>
<option value="UY">Uruguay</option>

Nice article! I think, that it misses an important technique, that uses checkboxes and :checked selector to approximate interactive elements.

Checkboxes and radio buttons can be used to create tabs, expandable areas, dialogs and other complex interactive controls without using Javascript. They are a lot more flexible and have better cross-browser compatibility than "dialog" and "summary".

This is very interesting. I can do some implementations of these with animations using a smart combination of HTML inputs combined with CSS. I think HTML/CSS can still go beyond, there are things for which JS was not necessary anymore and yet it's the norm.

Good article :D

Weird stuff... caniuse says no FF, but MDN says it's been there since 53. Unless there's more than one meaning of dialog. They both say no IE/Edge/Safari though.

Edit... nevermind, it's behind a flag in FF, but MDN shows that as green and caniuse shows it as red. TIL.
