问题


as you see in my snippet when buttons are hidden => display:none; my display was what i want. but after showing them my display became a mess (Especially in bigger than 1300" Display).

my code has two display (bigger than 1300") and (smaller than 1300").

please correct my codes for create same display in both case (with buttons & without them)

function Prev(current) {
  var prev_s = current.match(/\d/g);
  prev_s = prev_s.join("");
  prev_s--;
  prev_s = 'P_jmp' + prev_s;
  document.getElementById(prev_s).scrollIntoView();
}

function Next(current) {
  var next_s = current.match(/\d/g);
  next_s = next_s.join("");
  next_s++;
  next_s = 'N_jmp' + next_s;
  document.getElementById(next_s).scrollIntoView();
}

function btn_H_S(div_id) {
  document.getElementById(div_id).id = (div_id * (-1));
  if (div_id == "1") {
    for (x = 1; x < 14; x++) {
      document.getElementById("P_jmp" + x).style.display = "none";
      document.getElementById("N_jmp" + x).style.display = "none";
    }
  }
  if (div_id == "-1") {
    for (x = 1; x < 14; x++) {
      document.getElementById("P_jmp" + x).style.display = "block";
      document.getElementById("N_jmp" + x).style.display = "inline";
    }
  }
