  <scrt>
    const detect = document.querySelector("#detect");
    const wrapper = document.querySelector(".wrapper");
    const button = wrapper.querySelector("button");
    let adClasses = ["ad", "ads", "adsbox", "doubleclick", "ad-placement", "ad-placeholder", "adbadge", "BannerAd"];
    for(let item of adClasses){
      detect.classList.add(item);
    }
    let getProperty = window.getComputedStyle(detect).getPropertyValue("display");
    if(!wrapper.classList.contains("show")){
      getProperty == "none" ? wrapper.classList.add("show") : wrapper.classList.remove("show");
    }
    button.addEventListener("click", ()=>{
      wrapper.classList.remove("show");
    });
