Making accessible accordion

An accessible accordion is a type of interactive component that allows users to expand and collapse content, while also providing a good user experience for people with disabilities.

Accordions reduce the need to scroll when presenting multiple sections of content on a single page. They should be accessible through keyboard navigation and follow WAI-ARIA roles, states, and properties guidelines for accessibility.

An accordion-like interface can be created by using a sequence of <details> elements, which are expanding sections that can reveal or hide content. As we’ll see later, using the name attribute allows these components to simulate the behavior of typical accordions, in which just a single section can be open at a time, with other sections closing themselves when a new one is expanded.

This solution does not involve JavaScript. Only HTML and CSS for styling.

EU Digital Accessibility laws apply to all companies operating in the EU, regardless of origin

Websites are excellent because they can be accessed by almost anyone, anywhere. This allows you to sell your products and services from your country to anywhere in the world. While this is exciting, it also means that your website must adhere to their regulations and web accessibility rules.

The European Accessibility Act (EAA) will take effect in June 2025 and will require companies to comply with WCAG 2.1 Level AA standards for digital products and services sold in the EU.

This guide is intended to give organizations a path to global digital accessibility legislation, with a focus on the laws that expose companies operating on the EU market. What are these laws, what are the requirements, and what are the penalties for noncompliance? In responding to these questions, we explore deeper into the EU’s European Accessibility Act, which businesses must pay special attention to.

How to get the actual (real) background color of an HTML element

In many browsers, when no explicit background color is set for the <html>

or <body> elements, they inherit a transparent background.

However, browsers often render the default background as white for visual consistency, particularly in user interfaces where a clear background is expected. This can lead to confusion when using JavaScript to check computed styles.
