Paano gumawa: pangalatang grid

Alamin kung paano gumawa ng isang pinalakas na grid gamit ang CSS at JavaScript.

Lumikha ng pangalatang grid

Unang hakbang - Magdagdag ng HTML:

Grid: tatlong kolum
<div class="row">
  <div class="column" onclick="openTab('b1');" style="background:green;">Box 1</div>
  <div class="column" onclick="openTab('b2');" style="background:blue;">Box 2</div>
  <div class="column" onclick="openTab('b3');" style="background:red;">Box 3</div>
</div>
Pangalatang grid (default na nakahide)
<div id="b1" class="containerTab" style="display:none;background:green">
  Kung gusto mong magbukas ng container, magdagdag ng button na close
  <span onclick="this.parentElement.style.display='none'" class="closebtn">x</span>
  <h2>Box 1</h2>
  <p>Lorem ipsum..</p>
</div>
<div id="b2" class="containerTab" style="display:none;background:blue">
  <span onclick="this.parentElement.style.display='none'" class="closebtn">x</span>
  <h2>Box 2</h2>
  <p>Lorem ipsum..</p>
</div>
<div id="b3" class="containerTab" style="display:none;background:red">
  <span onclick="this.parentElement.style.display='none'" class="closebtn">x</span>
  <h2>Box 3</h2>
  <p>Lorem ipsum..</p>
</div>

第二步 - 添加 CSS：

创建三列：

/* 网格：三个等宽的列，彼此浮动 */
.column {
  float: left;
  width: 33.33%;
  padding: 50px;
  text-align: center;
  font-size: 25px;
  cursor: pointer;
  color: white;
}
.containerTab {
  padding: 20px;
  color: white;
}
/* 清除列后的浮动 */
.row:after {
  content: "";
  display: table;
  clear: both;
}
/* 图像内的可关闭按钮 */
.closebtn {
  float: right;
  color: white;
  font-size: 35px;
  cursor: pointer;
}

第三步 - 添加 JavaScript：

// 隐藏所有带有 class="containerTab" 的元素，除了与可点击的网格列匹配的元素
function openTab(tabName) {
  var i, x;
  x = document.getElementsByClassName("containerTab");
  for (i = 0; i < x.length; i++) {
    x[i].style.display = "none";
  }
  document.getElementById(tabName).style.display = "block";
}
