我正在关注 Youtube 上 Traversy Media 的题为“从头开始的响应式 HTML 和 CSS 侧边菜单”的教程(我会因为没有足够的声誉而发布链接),但我的侧导航存在一些问题。请注意在我单击左上角的 openSlideMenu() 图标之前单击它时的显示方式。我一直遵循老师的代码,但界面上似乎至少有4个问题。

  1. 有一个打开的标签符号位于 3 栏图标附近,无论菜单打开还是关闭,它都会保留。

  2. 单击打开时,侧导航远离页面左侧,在菜单和页面左侧之间创建了一个很大的空白间隙,不应存在间隙。

  3. 侧导航越过标题文本“响应式侧菜单”,从而阻止了文本的“e 菜单”部分,而标题文本应在侧导航移动时响应并移动,如教程中所述。

  4. 侧边导航中的 closeMenuButton() 的位置直接位于元素上方,而它应该位于右侧角落。

我的 HTML/Javascript 代码:

function openSlideMenu() {
  document.getElementById('side-menu').style.width = '250px';
  document.getElementById('side-menu').style.marginLeft = '250px';
}

function closeSlideMenu() {
  document.getElementById('side-menu').style.width = '0px';
  document.getElementById('side-menu').style.marginLeft = '0px';
}
body {
  font-family: "Arial", Serif;
  background-color: #f4f4f4;
  overflow-x: hidden;
}

.navbar {
  background-color: #3b5998;
  overflow: hidden;
  height: 63px;
}

.navbar a {
  float: left;
  display: block;
  color: #f2f2f2;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
  font-size: 17px;
}

.navbar ul {
  margin: 8px 0 0 0;
  list-style: none;
}

.navbar a:hover {
  background-color: #ddd;
  color: #000;
}

.side-nav {
  height: 100%;
  width: 0;
  position: fixed;
  z-index: 1;
  top: 0;
  left: 0;
  background-color: #111;
  opacity: 0.9;
  overflow-x: hidden;
  padding-top: 60px;
  transition: 0.5s;
}

.side-nav a {
  padding: 10px 10px 10px 30px;
  text-decoration: none;
  font-size: 22px;
  color: #ccc;
  display: block;
  transition: 0.3s;
}

.side-nav a:hover {
  color: #fff;
}

.side-nav .btn-close {
  postion: absolute;
  top: 0;
  right: 22px;
  font-size: 36px;
  margin-left: 50px;
}

# main {
  transition: margin-left 0.5s;
  padding: 20px;
  overflow: hidden;
  width: 100%;
}

@media(max-width: 568px) {
  .navbar-nav {
    display: none
  }
}

此外,老师有他在 Youtube 上的视频描述中生成的代码,您可以通过搜索“从头开始的响应式 HTML 和 CSS 侧边菜单”找到第一个结果。
