How this effect works
它是怎么工作的（中文）
HTML 自带 details/summary 元素：点击展开、自带键盘可达、零 JavaScript。要做的只有样式：去掉默认小三角，换成一个会旋转 45° 变成 × 的加号。需要「同时只开一个」时给 details 加同一个 name 属性（现代浏览器支持）。
How it works (English)
HTML's details/summary elements expand on click, are keyboard-accessible, and need no JavaScript. Styling is all that's left: remove the default marker and use a plus that rotates 45° into an ×. For 'only one open at a time', give the details elements the same name attribute (modern browsers support it).
