Code
<label class="chk"><input type="checkbox" checked><span class="box">✓</span>选项文字</label>
<style>
.chk { display: flex; align-items: center; gap: 11px; cursor: pointer; }
.chk input { position: absolute; opacity: 0; }
.chk .box { width: 25px; height: 25px; border-radius: 7px; border: 2px solid #C7C3BA;
display: grid; place-items: center; color: transparent; transition: all .18s; }
.chk input:checked + .box { background: #141414; border-color: #141414; color: #fff; }
.chk input:focus-visible + .box { outline: 2px solid #141414; outline-offset: 2px; }
</style><label class="flex cursor-pointer items-center gap-[11px]"><input type="checkbox" class="peer sr-only" checked>
<span class="grid h-[25px] w-[25px] place-items-center rounded-[7px] border-2 border-[#C7C3BA] text-transparent transition-all peer-checked:border-neutral-900 peer-checked:bg-neutral-900 peer-checked:text-white">✓</span>选项文字</label>
<!-- 注意：peer 要求 input 与 span 是兄弟且 input 在前 -->export function Checkbox({ label, defaultChecked }) {
const [on, setOn] = React.useState(!!defaultChecked);
return (<label style={{ display: "flex", alignItems: "center", gap: 11, cursor: "pointer" }}>
<input type="checkbox" checked={on} onChange={(e) => setOn(e.target.checked)} style={{ position: "absolute", opacity: 0 }} />
<span style={{ width: 25, height: 25, borderRadius: 7, display: "grid", placeItems: "center",
border: "2px solid " + (on ? "#141414" : "#C7C3BA"), background: on ? "#141414" : "transparent",
color: on ? "#fff" : "transparent", transition: "all .18s" }}>✓</span>{label}</label>);

How this effect works
它是怎么工作的（中文）
套路是「真 input 隐身 + 假方框替身」：label 包住 sr-only 的 input 和一个 span 方框，用 :checked + 相邻选择器给方框上色打勾。关键是别把 input 用 display:none 删掉——键盘焦点和表单语义都靠它，焦点样式画在替身 span 上。
How it works (English)
The pattern is 'real input goes invisible, fake box performs': a label wraps an sr-only input and a span box; :checked with the sibling selector fills the box and shows the check. Never display:none the input — keyboard focus and form semantics depend on it; draw the focus style on the stand-in span.
