  }
  $("-sharpwrap").html(a);
  $("-sharpwrap2").html(a);
  for (let i in $(".button")) {
    $(".button").eq(i).css({
      "background": `rgb(` + parseInt(Math.random() * 255) + `,` + parseInt(Math.random() * 255) + `,` +
        parseInt(Math.random() * 255) + `)`
    })
  }
  setInterval(() => {
    for (let i in $(".button")) {
      $(".button").eq(i).css({
        "background": `rgb(` + parseInt(Math.random() * 255) + `,` + parseInt(Math.random() * 255) + `,` +
