SVG Title vs. HTML Title Attribute

You know the title attribute? I can do this:

<div title="The Title">   I'm a div with a `title` </div>

And now if I’m on a device with a mouse pointer and hover the cursor over that element, I get…

Screenshot of standard text saying I'm a div with a title. A light gray tooltip is floating above the text next to the cursor that says The Title.

Which, uh, I guess is something. I sometimes use it for things like putting an expanded date or time on an element that uses shorthand for it. It’s a tiny bit of UX helpfulness reserved exclusively for sighted mouse users.

But it’s not particularly useful, as I understand it. Ire Aderinokun dug into how it’s used for the <abbr> element (a commonly cited example) and found that it’s not-so-great alone. She suggests a JavaScript-enhanced pattern. She also mentions that JAWS has a setting for announcing titles in there, so that’s interesting (although it sounds like it’s off by default).

I honestly just don’t know how useful title is for screen readers, but it’s certainly going to be nuanced.

I did just learn something about titles though… this doesn’t work:

<!-- Incorrect usage --> <svg title="Checkout"> </svg>

If you hover over that element, you won’t get a title display. You have to do it like this:

<!-- Correct usage --> <svg>   <title>Checkout</title>      <!-- More detail -->   <desc>A shopping cart icon with baguettes and broccoli in the cart.</desc> </svg>

Which, interestingly, Firefox 79 just started supporting.

When you use title like that, the hoverable area to reveal the title popup is the entire rectangle of the <svg>.

I was looking at all this because I got an interesting email from someone who was in a situation where the title popup only seemed to come up when hovering over the “filled in” pixels of an SVG, and not where transparent pixels were. Weird, I thought. I couldn’t replicate in my testing either.

Turns out there is a situation like this. You can apply a <title> within a <use> element, then the title only applies to those pixels that come in via the <use>.

If you remove the “white part” title, you’ll see the “black part” only comes up over the black pixels. Seems to be consistent across browsers. Just something to watch out for if that’s how you apply titles.

How I Put the Scroll Percentage in the Browser Title Bar

Some nice trickery from Knut Melvær.

Ultimately the trick boils down to figuring out how far you’ve scrolled on the page and changing the title to show it, like:

document.title = `$  {percent}% $  {post.title}`

Knut’s trick assumes React and installing an additional library. I’m sure that library does all kinds of smart stuff, but if you’re looking to do this “vanilla” style, I’d probably rock something like this…

const percentLabel = document.querySelector("#percent"); const originalTitle = document.title;  window.addEventListener("scroll", () => {   let scrollTop = window.scrollY;   let docHeight = document.body.offsetHeight;   let winHeight = window.innerHeight;   let scrollPercent = scrollTop / (docHeight - winHeight);   let scrollPercentRounded = Math.round(scrollPercent * 100);   percentLabel.innerHTML = scrollPercentRounded;   document.title = `($  {scrollPercentRounded}%) $  {originalTitle}`; });

Here’s a project, and here’s the deployed site so you can see it in action.

“The title ‘Front-End Developer’ is obsolete.”

That title is from the opening tweet of a thread from Benjamin De Cock. I wouldn’t go that far, myself. What I like about the term is that ‘Front-End’ literally means the browser, and while the job has been changing quite a lot — and is perhaps fracturing before our eyes — the fact that the job is about doing browser work is still true. We’re browser people. This was a point I tried to make in my “Ooooops I guess we’re full-stack developers now” talk.

I really like Benjamin’s sentiment though. There is a scourge of implementations of things on the web that are both heavier and worse because they re-implement something that the browser offers better and “for free.” Think sliders: scrolling behavior, snap points, fixed/sticky positioning, form controls, animation, etc.

Our industry seems to have acknowledged that backend and frontend developers require very different skills (even though they often use the exact same language), and yet it’s struggling to see there’s too much bundled into the term “front-end developer”.

That’s the tricky part. That’s at the heart of The Great Divide. There’s an awful lot of front-end developers where their job solely focuses on JavaScript. You could call them “JavaScript Engineers” or “JavaScript Developers,” and that feels OK. However, I’m not sure what you call someone who’s a great front-end developer, not particularly focused on JavaScript, but is on other aspects of the front end.

The modern frontend developer is most often than not a “Jack of all trades” mastering JS (or even just a framework) and barely tolerating HTML/CSS as a necessary evil. That’s understandable. I strongly think it’s a different specialization, and it’s too much for a single person.

Yep, it’s OK! The divide isn’t a bad thing; it’s just a thing. Front-end teams need JavaScript specialists and CSS specialists and accessibility specialists and performance specialists and animation specialists and internationalization specialists and, and, and, and. They don’t have to all be separate people. People can be good at multiple things. It’s just exceptionally rare that people are good at everything, even when scoped only to front-end skills.

Using the HTML title attribute

 Steve Faulkner:

User groups not well served by use of the title attribute

• Mobile phone users.
• Keyboard only users.
• Screen magnifier users.
• Screen reader users.
• Users with fine motor skill impairments.
• Users with cognitive impairments.

Sounds like in 2020, the only useful thing the title attribute can do is label an <iframe title="Contact Form"></iframe>.
