How to Create Accessible Infographics And Data Visualizations
Web Accessibility Initiative: Forms Tutorial
Forms are commonly used to provide user interaction on websites and in web applications. For example, login, registering, commenting, and purchasing. This tutorial shows you how to create accessible forms. The same concepts apply to all forms, whether they are processed client or server-side.
Aside from technical considerations, users usually prefer simple and short forms. Only ask users to enter what is required to complete the transaction or process; if irrelevant or excessive data is requested, users are more likely to abandon the form.
Forms can be visually and cognitively complex and challenging to use. Accessible forms are easier to use for everyone, including people with disabilities.
- People with cognitive disabilities can better understand the form and how to complete it, as making forms accessible improves the layout structure, instructions, and feedback.
- People using speech input can use the labels via voice commands to activate controls and move the focus to the fields that they have to complete.
- People with limited dexterity benefit from large clickable areas that include the labels, especially for smaller controls, such as radio buttons and checkboxes.
- People using screen readers can identify and understand form controls more easily because they are associated with labels, field sets, and other structural elements.

Forking is Beautiful
We’re very proud to announce that Vinny Green, a former WordPress community member, has started his fork, FreeWP. We strongly encourage anyone who disagrees with the direction WordPress is headed in to join up with Vinny and create an amazing fork of WordPress. Viva FreeWP!
Joost/Karim Fork
In open source, one thing that makes it even harder to ship great software is bringing together disparate groups of contributors who may have entirely different incentives or missions or philosophies about how to make great work. Working together on a team is such a delicate balance, and even one person rowing in the wrong direction can throw everyone else off.
That’s why periodically I think it is very healthy for open source projects to fork, it allows for people to try out and experiment with different forms of governance, leadership, decision-making, and technical approaches.
The beauty of open source is they can take all of the GPL code in WordPress and ship their vision. You don’t need permission, you can just do things. If they create something that’s awesome, we may even merge it back into WordPress, that ability for code and ideas to freely flow between projects is part of what makes open source such an engine for innovation. I propose that in a year we do a WordPress + JKPress summit, look at what we’ve shipped and learned in the process, which I’d be happy to host and sponsor in NYC next January 2026. The broader community will benefit greatly from this effort, as it’s giving us a true chance to try something different and see how it goes.

OpenAPI Specification
The OpenAPI Specification (OAS) defines a standard, language-agnostic interface to HTTP APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. When properly defined, a consumer can understand and interact with the remote service with a minimal amount of implementation logic.
An OpenAPI definition can then be used by documentation generation tools to display the API, code generation tools to generate servers and clients in various programming languages, testing tools, and many other use cases.

React & TypeScript: What is React.FC and Why should i use it?
React.FC is a type that stands for «Function Component» in React. It is a generic type that allows you to specify the props that a function component will accept.
Using React.FC can be helpful for a number of reasons:
It provides type safety for the props that a component expects to receive. This can help catch bugs early on and make your code easier to understand.
It makes it easier to refactor your component’s props. For example, if you want to rename a prop, the TypeScript compiler will catch any places where that prop is used and help you update them.
It makes it easier to see the expected shape of a component’s props just by looking at its type definition.
Everything You Need to Know About WPGraphQL
This article will explore GraphQL and WPGraphQL, delving into their core principles, architecture, and how they contrast with the WordPress REST API.
What is the difference between .js, .tsx and .jsx in React?
.js is JavaScript, plain and simple
.ts is TypeScript, Microsoft’s way of adding «concrete» types to JavaScript
.jsx is JavaScript but with JSX enabled which is React’s language extension to allow you to write markup directly in code
.tsx is similar to jsx except it’s TypeScript with the JSX language extension

SQLite no es una base de datos de juguete
SQLite es el DBMS más común del mundo, incluido en todos los sistemas operativos populares.
SQLite no tiene servidor.
Para quienes desarrollan, SQLite está integrado directamente en la aplicación.
Para todos los demás, existe una conveniente consola de base de datos (REPL), que se proporciona como un solo archivo (sqlite3.exe en Windows, sqlite3 en Linux / macOS).
WordPress Rest API extensions for going headless WP
I love the WordPress Rest API and switching more and more from theme development to a headless WP approach, with an nice front-end framework. Right now I’m favoring Nuxt.js, which is build on Vue.js (check out wuxt, my very own dockerized nuxt/wp development environment).
For using WPs full strength with the Rest API I’ve collected/build a useful snippet library with WordPress Rest API extensions. I’ll try to maintain the following list as development goes on. All of the following extensions can be embedded in the functions.php file. If you wondering about the wuxt_ prefix, I’ve got the code from my Wuxt project and the prefix is as good as anyone.
How to detect the user browser ( Safari, Chrome, IE, Firefox and Opera ) using JavaScript ?
Detecting the Safari browser: The user-agent of the Safari browser is “Safari”. This value is passed to indexOf() method to detect this value in the user-agent string. One additional check is required in the case of the Safari browser as the user-agent of the Chrome browser also includes the Safari browser’s user-agent. If both the user-agents of Chrome and Safari are in the user-agent, it means that the browser is Chrome, and hence the Safari browser value is discarded.
Browser detection using the user agent
When considering using the user agent string to detect which browser is being used, your first step is to try to avoid it if possible. Start by trying to identify why you want to do it.
interact.js: JavaScript drag and drop, resizing, and multi-touch gestures for modern browsers
interact.js takes a slightly different approach compared to most drag and drop libraries. To give you as much control as possible, it tries to provide a simple, flexible API that gives you all the pointer event data you’ll need to move elements around.
The library doesn’t even do any moving at all! This is great because you decide exactly what feedback your users get. You can drag elements, draw on a canvas or (if you really need to) scroll the page.
Resizable & Draggable Dialog In Pure JavaScript
A vanilla JavaScript library to create a draggable & resizable dialog popup without any frameworks or libraries (e.g. jQuery UI).
To move, drag from the title bar of the dialog box.
To resize, drag from any edge or any corner of the dialog box.
Comparing Various Ways to Hide Things in CSS
Developers most commonly use display: none to hide the content on the page. Unfortunately, this way of hiding content isn’t bulletproof because now that content is now “inaccessible” to screen readers. It’s tempting to use it, but especially in cases where something is only meant to be visually hidden, don’t reach for it.
Traducción con Pods de WordPress y WPML
en el caso de que se estén empleando plugins para el desarrollo de una solución WordPress que no sean compatibles con WPML, por ejemplo PODS, una solución interesante, es duplicar el mismo post o tipo de contenido, que ha sido creado con elementos del plugin incompatible y aprovechar cada versión para cada uno de los idiomas que hemos configurado para nuestro sitio, diferenciando cada post con una nomenclatura, por ejemplo con el diminutivo (_en, _es, _fr) del idioma en el slug o (-EN, -ES, -FR) en el nombre del mismo.
Para que luego WordPress distnga cual de esos bloques o contenidos pertenece al idioma concreto, utilizamos la constante ICL_LANGUAGE_CODE, definida por WPML, que se pueden emplear como parte del nuestro tema, para poder invocar el contenido de un post u otro en dependencia del idioma actual con el que se está navegando en nuestro sitio, idioma almacenado en la constante antes mencionada.
De esta manera un ejemplo podría ser:
if (ICL_LANGUAGE_CODE == 'en')
3D TagCloud.js rotating with mouse
const TagCloud = require('TagCloud');
const container = '.tagcloud';
const texts = [
'3D', 'TagCloud', 'JavaScript',
'CSS3', 'Animation', 'Interactive',
'Mouse', 'Rolling', 'Sphere',
'6KB', 'v2.x',
];
const options = {};
TagCloud(container, texts, options);
Response: json() method
The json() method of the Response interface takes a Response stream and reads it to completion. It returns a promise which resolves with the result of parsing the body text as JSON.
const myList = document.querySelector("ul");
const myRequest = new Request("products.json");
fetch(myRequest)
.then((response) => response.json())
.then((data) => {
for (const product of data.products) {
const listItem = document.createElement("li");
listItem.appendChild(document.createElement("strong")).textContent = product.Name;
listItem.append(` can be found in ${product.Location}. Cost: `);
listItem.appendChild(document.createElement("strong")).textContent = `£${product.Price}`;
myList.appendChild(listItem);
}
})
.catch(console.error);
EventTarget: addEventListener() method
The Function.prototype.bind() method lets you establish a fixed this context for all subsequent calls — bypassing problems where it’s unclear what this will be, depending on the context from which your function was called. Note, however, that you’ll need to keep a reference to the listener around so you can remove it later.
class Something {
name = "Something Good";
constructor(element) {
// bind causes a fixed `this` context to be assigned to `onclick2`
this.onclick2 = this.onclick2.bind(this);
element.addEventListener("click", this.onclick1, false);
element.addEventListener("click", this.onclick2, false); // Trick
}
onclick1(event) {
console.log(this.name); // undefined, as `this` is the element
}
onclick2(event) {
console.log(this.name); // 'Something Good', as `this` is bound to the Something instance
}
}
const s = new Something(document.body);

Avoid invisible text during font loading
font-display is an API for specifying font display strategy. swap tells the browser that text using this font should be displayed immediately using a system font. Once the custom font is ready, the system font is swapped out.
Reduce web font size
Web font optimization is a critical piece of the overall performance strategy. Each font is an additional resource, and some fonts may block rendering of the text, but just because the page is using WebFonts doesn’t mean that it has to render slower. On the contrary, optimized fonts, combined with a judicious strategy for how they are loaded and applied on the page, can help reduce the total page size and improve page rendering times.
The Shapes of CSS
CSS is capable of making all sorts of shapes. Squares and rectangles are easy, as they are the natural shapes of the web. Add a width and height and you have the exact size rectangle you need. Add border-radius and you can round that shape, and enough of it you can turn those rectangles into circles and ovals.
Evaluating Web Accessibility Overview
When developing or redesigning a website or web application, evaluate accessibility early and throughout the development process to identify accessibility problems early, when it is easier to address them.
There are evaluation tools that help with evaluation. However, no tool alone can determine if a site meets accessibility standards. Knowledgeable human evaluation is required to determine if a site is accessible.
WordPress: how to add a default title to your posts
This came up on the Fediverse: @kev@log.kevquirk.com wanted to automatically add titles to the posts on his microblog.
This automation would have to be compatible with all the editors, including the mobile app.
I think may be a fairly common request when one uses their WordPress site as microblogging platform. When you share quick updates with your friends, be it a picture, a video, a sentence or two, you don’t really want to have to think of a title for that update. The editor should enable you to share, not get in the way.
