Tip Calculator That Doesn't Accept Negative Values

Feedback on refactoring the following block of code from my JS script would be greatly appreciated:

container.addEventListener("click", (e) => {
  if (e.target.classList.contains("percent") || e.target === customTipInput) {
    if (document.querySelector(".percent.selected")) {
      document.querySelector(".percent.selected").classList.remove("selected");
    }
    e.target !== customTip && e.target !== customTipInput
      ? e.target.classList.add("selected")
      : customTip.classList.add("selected");

    e.target !== customTipInput && e.target !== customTip
      ? (selectedTip = e.target.textContent)
      : (selectedTip = customTipInput.value);
  }
  calcTotals();
});

All other feedback welcome and encouraged.
