Advanced guide to the CSS toggle() pseudo-class

In mid-April 2022, Chromium announced plans to prototype CSS Toggles, a new and unofficial CSS feature that introduces a declarative way to associate and manipulate toggleable values on elements. This feature, which includes the toggle() functional pseudo-class, allows developers to create custom states for elements, enhancing styling and interactivity without relying on JavaScript. CSS Toggles introduces properties like toggle-visibility and toggle-group, enabling developers to build components such as tabs, accordions, and other disclosure widgets with improved accessibility. The toggle() pseudo-class allows for the selection of elements based on their toggle state, offering a new level of customization for web design. However, as this feature is still in draft form, its specifications may change before official implementation. CSS Toggles promises to be a valuable tool for CSS authors by simplifying the process of adding interactivity to HTML elements, though it will require time to master its syntax fully.
