made a small change to add a div that displays the Id of the elements on the page, was helpful on a recent site I had to debug, so I'll save it here

looks like this ^ some labels are still had to read, maybe this will be on its own separate Bookmarklet later

javascript: (function () {
  var styleEl = document.getElementById("css-layout-hack");
  if (styleEl) {
    styleEl.remove();
    const elems = document.querySelectorAll(".css-name-dbg");
    [...elems].forEach((elem) => {
      elem.remove();
    });
    return;
  }
  styleEl = document.createElement("style");
  styleEl.id = "css-layout-hack";
  styleEl.innerHTML =
    "div.css-name-dbg{   text-shadow: 3px 3px 4px white; position: fixed;    background-color: rgba(255, 255, 255, 0) !important;    outline: 0px !important;    color: rgb(0, 0, 0) !important;    padding: 2px !important;} * { background:#000!important;color:#0f0!important;outline:solid #f00 1px!important; background-color: rgba(255,0,0,.2) !important; }    * * { background-color: rgba(0,255,0,.2) !important; }    * * * { background-color: rgba(0,0,255,.2) !important; }    * * * * { background-color: rgba(255,0,255,.2) !important; }    * * * * * { background-color: rgba(0,255,255,.2) !important; }    * * * * * * { background-color: rgba(255,255,0,.2) !important; }    * * * * * * * { background-color: rgba(255,0,0,.2) !important; }    * * * * * * * * { background-color: rgba(0,255,0,.2) !important; }    * * * * * * * * * { background-color: rgba(0,0,255,.2) !important; }";
  document.body.append(styleEl);
  const elems = document.querySelectorAll("[id]");
  [...elems].forEach((elem) => {
    const divroot = document.createElement("div");
    divroot.setAttribute("class", "css-name-dbg");
    divroot.textContent = "#" + elem.id;
    elem.insertAdjacentElement("afterbegin", divroot);
  });

I've added the id as a separate bookmarket, not sure if I can add an onclick copy-to-clipboard function to the label, maybe I'll try that latter
