推送菜单-如何推送正文

Question

我有一个在右边打开的菜单。我的问题是，我想在我打开菜单后调整身体的大小。菜单是300px宽的，我想要调整身体的大小，以占据屏幕的其余部分。我看过一些例子，但它们所做的只是移动身体，使身体的一部分看不见，不在屏幕上。您可以查看我的示例here

<nav class="side-nav hidden">

    <div>
        <div class="open-menu-side" id="side">
            <button class="hamburger hamburger--squeeze" type="button">
              <span class="hamburger-box">
                <span class="hamburger-inner"></span>
              </span>
            </button>
        </div>

        <ul class="side-nav-ul">
            <a href="#"><li class="block">Home</li></a>
            <a href="#"><li class="block">Profile</li></a>
            <a href="#"><li class="block">Blogs</li></a>
            <a href="#"><li class="block">Following</li></a>
            <a href="#"><li class="block">Settings</li></a>
            <a href="#"><li class="block">Logout</li></a>
        </ul>
    </div>
</nav>
<header id="pushed">
    <nav>
        <div class="open-menu" id="main">
            <button class="hamburger hamburger--squeeze" type="button">
              <span class="hamburger-box">
                <span class="hamburger-inner"></span>
              </span>
            </button>
        </div>
        <div class="brand">Login!</div>

正如评论中提到的，这就是你可以做的。当菜单打开时，向HTML body添加一个类，并添加一个与菜单宽度相等的padding-right。

​

$(".hamburger").on("click", function() {
  $(".hamburger").toggleClass("is-active");
  //add menu-active class to document body
  $('body').toggleClass('menu-active');
  $(".side-nav").toggleClass("hidden");
  if ($("#side").hasClass("is-active")) {
    $("#main").toggleClass("hidden");
  } else if (!$("#side").hasClass("is-active")) {
    $("#main").toggleClass("hidden");
  }
});

html,
body {
  padding: 0;
  margin: 0;
  height: 100%;
  background-color: black;
  box-sizing: border-box;
}

button:focus {
  outline: 0;
}

a {
  color: #fff;
}

a:hover {
  color: #fff;
  text-decoration: none;
}

.side-nav {
  position: absolute;
  background-color: gray;
  width: 300px;
  height: 100%;
  z-index: 1;
  right: 0;
}

.open-menu-side {
  position: relative;
  display: block;
  height: 80px;
  width: 100%;
  text-align: center;
  float: right;
}

.side-nav-ul {
  position: relative;
  display: inline-block;
  width: 100%;
  height: 100%;
  list-style: none;
  font-size: 28px;
  color: #fff;
}

.block {
  height: 40px;
}

header {
  height: 80px;
  background-color: #fff;
}

.brand {
  display: inline-block;
}

.img-menu img {
  height: 50px;
  width: 50px;
  border-radius: 50%;
  border: solid 1px black;
  float: left;
}

.hidden {
  position: absolute;
  right: -300px;
}

#pushed {
  position: relative;
}

#main {
  float: right;
}

.hamburger {
  padding: 15px 15px;
  height: 100%;
  display: inline-block;
  cursor: pointer;
  transition-property: opacity, filter;
  transition-duration: 0.15s;
  transition-timing-function: linear;
  font: inherit;
  color: inherit;
  text-transform: none;
  background-color: transparent;
  border: 0;
  margin: 0;
  overflow: visible;
}

.hamburger:hover {
  opacity: 0.7;
}

.hamburger-box {
  width: 40px;
  height: 24px;
  display: inline-block;
  position: relative;
}

.hamburger-inner {
  display: block;
  top: 50%;
  margin-top: -2px;
}

.hamburger-inner,
.hamburger-inner::before,
.hamburger-inner::after {
  width: 40px;
  height: 4px;
  background-color: #000;
  border-radius: 4px;
  position: absolute;
  transition-property: transform;
  transition-duration: 0.15s;
  transition-timing-function: ease;
}

.hamburger-inner::before,
.hamburger-inner::after {
  content: "";
  display: block;
}

.hamburger-inner::before {

  transform: rotate(45deg);
  transition-delay: 0.12s;
  transition-timing-function: cubic-bezier(0.215, 0.61, 0.355, 1);
}

.hamburger--squeeze.is-active .hamburger-inner::before {

  transition: bottom 0.075s ease, transform 0.075s 0.12s cubic-bezier(0.215, 0.61, 0.355, 1);
}

.hello-text {
  text-align: right;
  color: #fff;
  font-size: 22px;

/*add padding-right when menu is active*/
body.menu-active {
  padding-right: 300px;
