They are both URL paths. They have different names, though.

<!-- root-relative -->
<a href="./dogs.html">Dogs</a>

<!– absolute –>
<a href=”/dogs.html”>Dogs</a>

There are also fully-qualified URLs that would be like:

<!-- fully qualified -->
<a href="https://website.com/dogs.html">Dogs</a>

Fully-qualified URL’s are pretty obvious in what they do — that link takes you to that exact place. So, let’s look those first two examples again.

To update those values from JavaScript, you’d:

let root = document.documentElement;

root.addEventListener(“mousemove”, e => {
root.style.setProperty(‘–mouse-x’, e.clientX + “px”);
root.style.setProperty(‘–mouse-y’, e.clientY + “px”);
});

That’s all.

It began, as many things do, with a silly conversation. In this case, I was talking with our Front End Technology Competency Director (aka “boss man”) Mundi Morgado.

It went something like this…

Mundi Morgado I want you to build a visual screen reader.”

Nathan Smith Who what now?

Mundi Morgado I want a CSS library that allows you to see the structure of a document. It shouldn’t use class so that you’re forced to focus on semantics. Also, …

I kicked off a really poppin’ Twitter thread the other day:

What are the LOWEST hanging fruit of web performance? Nothing fancy, anyone can do, big impact.

Gzip. Optimize stuff. Reduce requests…

What are other big ones?

So, I decided to round up all the ideas (both my own and yours) around that in a post over on the Media Temple blog.

These are the things we dive into in that post:…
