切换控制是通过修改 html 根节点来控制的，因此需要修改 html 根节点代码:

<html lang="en">
//改为：
<html lang="en" data-color-mode="light">

js:

// 切换按钮
function set_mode_toggle(e) {
    let t = !0, mode = "dark";
    "true" === e.getAttribute("aria-checked") && (t = !1 , mode = "light")
        e.setAttribute("aria-checked", String(t))
        change_mode(mode);
}
// 改变模式 并设置 cookie
function change_mode(e) {
    const t = document.querySelector("html[data-color-mode]");
    if (e === "dark") document.cookie = "night=1;path=/";
    else document.cookie = "night=0;path=/"
    t && t.setAttribute("data-color-mode", e)
}
// 获取当前模式
function get_user_scheme_mode() {
    const e = document.querySelector("html[data-color-mode]");
    if (!e)
        return;
    const t = e.getAttribute("data-color-mode");
    return "auto" === t ? function() {
        if (get_sys_scheme_mode("dark"))
            return "dark";
        if (get_sys_scheme_mode("light"))
            return "light";
    }() : t
}
// 获取系统模式 先判断 cookie 在获取系统的
function get_sys_scheme_mode(e) {
    let night = document.cookie.replace(/(?:(?:^|.*;\s*)night\s*\=\s*([^;]*).*$)|^.*$/, "$1")
    if (night){
        if(night === '0'){
            return false
        }else if(night === '1'){
            return true
        }
    }else
    return window.matchMedia && window.matchMedia(`(prefers-color-scheme: ${e})`).matches
}
!async function() {
    const e = document.querySelector(".js-promo-color-modes-toggle");

        if (!e)
            return;

toggle_btn[0]? toggle_btn[0].addEventListener('click',function (e) {
    set_mode_toggle(e.currentTarget)
},false):false
