Buongiorno a voi community, spero stiate bene

Vi scrivo per un supporto su JS, linguaggio che sto ancora cercando di capire e che faccio fatica a capire.
Vorrei dunque sapere come poter posizionare determinate istruzioni per essere eseguite su un div dalla classe grid-container, e altre istruzioni che vengano eseguite su dei div con classe baby-grid-container

Il codice in questione è questo:
codice:
document.querySelectorAll("[data-fluent-text]").forEach((element) => {  new FluentButton(element, {
    text: element.dataset.fluentText,
    icon: element.dataset.fluentIcon,
    outerReveal: true,
  });
});

document.querySelectorAll("[data-fluent-text1]").forEach((element) => {
  new FluentButton(element, {
    text1: element.dataset.fluentText1,
    icon1: element.dataset.fluentIcon1,
    outerReveal: true,
  });
});
Qualora voleste il codice completo per sapere meglio come poter risolvere la questione, eccolo qui:
codice:
function _defineProperty(obj, key, value) {  if (key in obj) {
    Object.defineProperty(obj, key, {
      value: value,
      enumerable: true,
      configurable: true,
      writable: true,
    });
  } else {
    obj[key] = value;
  }
  return obj;
}
class FluentButton {
  constructor(rootEl, { text, icon, text1, icon1, outerReveal, onClick }) {
    this.rootEl =
      typeof rootEl === "string" ? document.querySelector(rootEl) : rootEl;
    if (FluentButton.elements.has(this.rootEl)) return;
    FluentButton.elements.add(this.rootEl);

    this.rootEl.innerHTML = FluentButton.createHTML({
      text,
      icon,
      text1,
      icon1,
    });
    this.el = this.rootEl.firstElementChild;

    if (onClick) this.el.addEventListener("click", onClick);
    this.el.addEventListener("touchstart", this.startRipple);
    this.el.addEventListener("mousedown", this.startRipple);
    this.el.onmousedown = this.el.ontouchstart = this.addPressedState;
    this.el.onmouseup =
      this.el.onmouseleave =
      this.el.ontouchend =
        this.removePressedState;

    if (!outerReveal) this.el.onmousemove = this.updateCoordinates;
    else {
      FluentButton.outerRevealElements.set(
        this.el,
        this.getElementDimensions(this.el)
      );
      if (!FluentButton.observingOuterReveal) this.observeOuterReveal();
    }
  }

  updateCoordinates({ pageX, pageY, currentTarget }) {
    const x = pageX - currentTarget.offsetLeft;
    const y = pageY - currentTarget.offsetTop;

    currentTarget.style.setProperty("--x", `${x}px`);
    currentTarget.style.setProperty("--y", `${y}px`);

    return { x, y };
  }

  startRipple({ currentTarget }) {
    currentTarget.classList.remove("fluent-btn--ripple"); // remove prev
    // Add again to (re)start animation
    setTimeout(() => currentTarget.classList.add("fluent-btn--ripple"), 25);
  }
  addPressedState({ currentTarget }) {
    currentTarget.classList.add("fluent-btn--pressed");
  }
  removePressedState({ currentTarget }) {
    currentTarget.classList.remove("fluent-btn--pressed");
  }

  observeOuterReveal() {
    FluentButton.observingOuterReveal = true;

    window.addEventListener("resize", this.updateElementDimensions.bind(this));
    window.addEventListener("mousemove", (event) => {
      window.requestAnimationFrame(this.updateOuterReveal.bind(this, event));
    });
    window.addEventListener("touchmove", ({ touches }) => {
      const [{ clientX, clientY }] = touches;
      const position = { pageX: clientX, pageY: clientY };
      window.requestAnimationFrame(this.updateOuterReveal.bind(this, position));
    });
  }

  updateOuterReveal({ pageX, pageY }) {
    for (const [el, { width, height }] of FluentButton.outerRevealElements) {
      const { x, y } = this.updateCoordinates({
        pageX,
        pageY,
        currentTarget: el,
      });

      if (this.isInRevealThreshold({ x, y, width, height })) {
        el.classList.add("fluent-btn--reveal");
      } else {
        el.classList.remove("fluent-btn--reveal");
      }
    }
  }

  isInRevealThreshold({ x, y, width, height }) {
    const threshold = FluentButton.outerRevealThreshold;
    return (
      x > -threshold &&
      x < width + threshold &&
      y > -threshold &&
      y < height + threshold
    );
  }

  getElementDimensions(el) {
    const { width, height } = el.getBoundingClientRect();
    return { width, height };
  }
  updateElementDimensions() {
    for (const [el] of FluentButton.outerRevealElements) {
      FluentButton.outerRevealElements.set(el, this.getElementDimensions(el));
    }
  }

  destroy() {
    this.rootEl.innerHTML = "";
    FluentButton.outerRevealElements.delete(this.el);
    FluentButton.elements.delete(this.rootEl);
  }
}

_defineProperty(FluentButton, "elements", new Set());
_defineProperty(FluentButton, "outerRevealElements", new Map());
_defineProperty(FluentButton, "outerRevealThreshold", 75);
_defineProperty(FluentButton, "observingOuterReveal", false);

_defineProperty(
  FluentButton,
  "createHTML",
  ({ text, icon }) => `
      <div class="fluent-btn">
        <div class="fluent-btn__btn">
          <div class="polaroid little-resize">
            <img draggable="false" src="${icon}" alt="">
            <div class="container">${text}</div>
          </div>
        </div>
      </div>`
);

//PROBLEMA

document.querySelectorAll("[data-fluent-text]").forEach((element) => {
  new FluentButton(element, {
    text: element.dataset.fluentText,
    icon: element.dataset.fluentIcon,
    outerReveal: true,
  });
});

document.querySelectorAll("[data-fluent-text1]").forEach((element) => {
  new FluentButton(element, {
    text1: element.dataset.fluentText1,
    icon1: element.dataset.fluentIcon1,
    outerReveal: true,
  });
});
Grazie in anticipo della risposta ,
