Kuhakisha: Sidebar yenye

Paa sidebar inayofunguka

Mwaka wa kwanza - Ongeza HTML:

<div id="mySidebar" class="sidebar">
  <a href="javascript:void(0)" class="closebtn" onclick="closeNav()">×</a>
  <a href="#">About</a>
  <a href="#">Serivisi</a>
  <a href="#">Wafanyikiaji</a>
  <a href="#">Wasifu</a>
</div>
<div id="main">
  <button class="openbtn" onclick="openNav()">☰ Kufungua Sidebar</button>
  <h2>Sidebar Inayotumika Kwa Kupima</h2>
  <p>Ujumbe...</p>
</div>

Mwaka wa pili - Ongeza CSS:

/* Menu ya sidebar */
.sidebar {
  height: 100%; /* 100% uwezo wa ukubwa wa upeo wa mji */
  width: 0; /* 0 upo - Tumia JavaScript ili kubadilisha kufupishwa hii seti */
  position: fixed; /* Ili iwe katika eneo lake */
  z-index: 1; /* Ili iwe nje ya wengine */
  top: 0;
  left: 0;
  background-color: #111; /* Kijani */
  overflow-x: hidden; /* Kamilika uharibifu wa uharifu wa wingu wa horizontali */
  padding-top: 60px; /* Ingiza ujumbe kwa kumekadiri ukabaki wa kwanza 60px */
  transition: 0.5s; /* Matokeo wa ukweli wa 0.5 sekunde kwa kusuliza sidebar */
}
/* Lingi za sidebar */
.sidebar a {
  padding: 8px 8px 8px 32px;
  text-decoration: none;
  font-size: 25px;
  color: #818181;
  display: block;
  transition: 0.3s;
}
/* Kisha hata kama kifurahishe katika lingi za navigation, huzu rangi yake */
.sidebar a:hover {
  color: #f1f1f1;
}
/* 关闭按钮的位置和样式（右上角） */
.sidebar .closebtn {
  position: absolute;
  top: 0;
  right: 25px;
  font-size: 36px;
  margin-left: 50px;
}
/* 用于打开侧边栏的按钮 */
.openbtn {
  font-size: 20px;
  cursor: pointer;
  background-color: #111;
  color: white;
  padding: 10px 15px;
  border: none;
}
.openbtn:hover {
  background-color: #444;
}
/* 设置页面内容样式 - 如果您想在打开侧边导航时将页面内容向右推动，请使用此样式 */
#main {
  transition: margin-left .5s; /* 如果您想要过渡效果 */
  padding: 20px;
}
/* 在高度小于 450 像素的小屏幕上，更改侧边栏的样式（减少内边距和字体大小） */
@media screen and (max-height: 450px) {
  .sidebar {padding-top: 15px;}
  .sidebar a {font-size: 18px;}
}

第三步 - 添加 JavaScript：

/* 将侧边栏的宽度设置为 250px，并将页面内容的左外边距设置为 250px */
function openNav() {
  document.getElementById("mySidebar").style.width = "250px";
  document.getElementById("main").style.marginLeft = "250px";
}
/* 将侧边栏的宽度设置为 0，并将页面内容的左外边距设置为 0 */
function closeNav() {
  document.getElementById("mySidebar").style.width = "0";
  document.getElementById("main").style.marginLeft = "0";
}
