Expand/Collapse Widget Demonstration
These interactive modules illustrate accessible expand/collapse behavior using buttons that control dedicated content regions. Each controlled region is wrapped in an element bearing the details class for consistent styling and scripting.
Basic Toggle with Status Update
This expandable panel uses a single toggle button to reveal or conceal supplemental information. As the panel opens, the button text updates to reflect the new state, and the symbol rotates to provide a visual cue.
The controlled region also sets aria-live="polite" to announce the change to assistive technologies, ensuring the experience remains inclusive.
Accordion with Single-Open Constraint
Prioritize clarity and simplicity. Use contrast, whitespace, and hierarchy to guide attention. Consistent iconography and motion help reinforce meaning for interactive elements.
Adhere to established patterns for controls to reduce cognitive load. For expand/collapse interfaces, ensure keyboard and screen-reader compatibility, providing meaningful labels and status indicators.
Each button carries the aria-controls attribute linking it to the corresponding content container. The script manages the hidden state, guaranteeing that only one panel remains open at a time within this accordion.
