使 P 标记忽略父 Div

Question

我的画布外菜单有问题。当菜单打开时，其中的 p 标签似乎会随着它的展开而改变它们的左边距。我希望我的 p 标签完全忽略菜单的打开和关闭并保持它们的文本对齐。这是我想要它做的一个想法：https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_sidenav_push

将其与我当前的代码进行比较：

function openNav() {
  document.getElementById("nav").style.width = "250px";
  document.getElementById("burger").style.left = "260px";
}

function closeNav() {
  document.getElementById("nav").style.width = "0";
  document.getElementById("burger").style.left = "10px";
}

* {
  margin: 0;
  madding: 0;
}

html, body {
  height: 100%;
}

body {
  font-family: sans-serif;
}

nav {
  position: absolute;
  top: 0;
  left: 0;
  display: inline-block;
  height: 100%;
  background-color: #333;
  color: #fff;
  padding-top: 30px;
  text-align: center;
  width: 0;
  white-space: nowrap;
  overflow-x: hidden;
  transition: width 1.5s;
}

.close {
  cursor: pointer;
  position: absolute;
  top: 5px;
  right: 15px;
  font-size: 2em;
}

nav p {
  cursor: pointer;
  display: block;
  font-size: 1.7em;
  margin: 30px auto;
  white-space: nowrap;
}

nav p:hover {
  opacity: 0.8;
}

.burger {
  will-change: left;
  position: absolute;
  left: 10px;
  cursor: pointer;
  font-size: 2em;
  z-index: 1;
  transition: 1.5s;
}

<nav id="nav">
  <span class="close" onclick="closeNav()">&times;</span>
  <p>Home</p>
  <p>About</p>
  <p>Blog</p>
  <p>Contact</p>
</nav>

<span class="burger" id="burger" onclick="openNav()">&#9776;</span>

本质上，我希望 p 标签的行为就像它们是绝对定位的，但在导航扩展时居中。

Answer 1

将您的<p> 标签包围在另一个<div> 中，无论<nav> 是否移动，该标签都将被静态定位。然后对其应用居中对齐：

function openNav() {
  document.getElementById("nav").style.width = "250px";
  document.getElementById("burger").style.left = "260px";
}

function closeNav() {
  document.getElementById("nav").style.width = "0";
  document.getElementById("burger").style.left = "10px";
}

* {
  margin: 0;
  madding: 0;
}

html, body {
  height: 100%;
}

body {
  font-family: sans-serif;
}

nav {
  position: absolute;
  top: 0;
  left: 0;
  display: inline-block;
  height: 100%;
  background-color: #333;
  color: #fff;
  padding-top: 30px;
  width: 0;
  white-space: nowrap;
  overflow-x: hidden;
  transition: width 1.5s;
}

.close {
  cursor: pointer;
  position: absolute;
  top: 5px;
  right: 15px;
  font-size: 2em;
}

nav p {
  cursor: pointer;
  display: block;
  font-size: 1.7em;
  margin: 30px 0;
  white-space: nowrap;
}

#pHolder{
   margin-left: 75px;
   width: 80px;
   text-align: center;
}
nav p:hover {
  opacity: 0.8;
}

.burger {
  will-change: left;
  position: absolute;
  left: 10px;
  cursor: pointer;
  font-size: 2em;
  z-index: 1;
  transition: 1.5s;
}

<nav id="nav">
  <span class="close" onclick="closeNav()">&times;</span>
  <div id="pHolder">
  <p>Home</p>
  <p>About</p>
  <p>Blog</p>
  <p>Contact</p>
  </div>
</nav>

<span class="burger" id="burger" onclick="openNav()">&#9776;</span>

Answer 2

不要更改width，而是保持宽度不变并更改nav 的left 对齐方式

试试这个

function openNav() {
  document.getElementById("nav").style.left = "0px";
  document.getElementById("burger").style.left = "260px";
}

function closeNav() {
  document.getElementById("nav").style.left = "-250px";
  document.getElementById("burger").style.left = "10px";
}

* {
  margin: 0;
  madding: 0;
}

html, body {
  height: 100%;
}

body {
  font-family: sans-serif;
}

nav {
  position: absolute;
  top: 0;
  left: -250px;
  display: inline-block;
  height: 100%;
  background-color: #333;
  color: #fff;
  padding-top: 30px;
  text-align: center;
  width: 250px;
  white-space: nowrap;
  overflow-x: hidden;
  transition: left 1.5s;
}

.close {
  cursor: pointer;
  position: absolute;
  top: 5px;
  right: 15px;
  font-size: 2em;
}

nav p {
  cursor: pointer;
  display: block;
  font-size: 1.7em;
  margin: 30px auto;
  white-space: nowrap;
}

nav p:hover {
  opacity: 0.8;
}

.burger {
  will-change: left;
  position: absolute;
  left: 10px;
  cursor: pointer;
  font-size: 2em;
  z-index: 1;
  transition: 1.5s;
}

<nav id="nav">
  <span class="close" onclick="closeNav()">&times;</span>
  <p>Home</p>
  <p>About</p>
  <p>Blog</p>
  <p>Contact</p>
</nav>

<span class="burger" id="burger" onclick="openNav()">&#9776;</span>
