A modern marquee element

The type=number state is not appropriate for input that happens to only consist of numbers but isn't strictly speaking a number. For example, it would be inappropriate for credit card numbers or US postal codes. A simple way of determining whether to use type=number is to consider whether it would make sense for the input control to have a spinbox interface (e.g. with "up" and "down" arrows). Getting a credit card number wrong by 1 in the last digit isn't a minor mistake, it's as wrong as getting every digit incorrect. So it would not make sense for the user to select a credit card number using "up" and "down" buttons. When a spinbox interface is not appropriate, type=text is probably the right choice (possibly with an inputmode or pattern attribute).

inputmode="decimal" or inputmode="number" fit better for these cases.

An accessibility decision tree for the alt attribute

Video elements can be responsive now. Here's how.

Sometimes ARIA is needed to convey informations such as a link pointing to the current page.

About microdata:

Labelling things properly is still a powerful act, especially when it involves repetition and relationship-building.

What the post is missing is: how building these connections are useful? Ok it's great for AI models that are parsing the site...

Getting started with Microdata

A rating UI pattern with smileys: only built with HTML and css.

• They are memorable
• They can be typed or said
• They looks nicer. They're aesthetic. They show care.
• They remove the middle-man: only the URL can be used!
• They are enough: using 36 characters with 4 character URLs give 1.679.616 unique combinations

Here’s how I do it: Save my HTML file as the URL name, with no extension. Instead of “hi.html”, I save it as “hi” in my public web root.

Then, assuming the Nginx web server, add this line to my http block: default_type text/html;
