  1. 为您的元素设置 CSS3 transition
  2. 创建一个 class 使您的元素 100vw100vh(视口宽度高度单位)
  3. 在点击时添加 class

$("#box").on("click", function() {
  $(this).toggleClass("fullScreen");
});
html, body{height:100%;margin:0;}

/* YOUR BOX */
#box{
  position: fixed;
  overflow: hidden; /* in order to contain content */
  
  /* The initial styles: */
  border-radius: 25px;
  background: red;
  left:50px; bottom:50px;
  width: 50px;
  height: 50px;
  

  /* TRANSITION TO THE RESCUE */
          transition: 0.7s;
  -webkit-transition: 0.7s;
}

/* ADD THIS CLASS WITH JS */
#box.fullScreen{
  /* Your override styles: */
  border-radius: 0;
  background: gold;
  left:0; bottom:0;
  width: 100vw;
  height:100vh;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="box">CLICK</div>

您可以使用transform: scale( )按比例上下缩放全屏框。缩放也会影响框的内容。小版本的盒子与全屏盒子具有相同的纵横比。

例子

$("#box").on("click", function() {
  $(this).toggleClass("fullScreen");
});
html, body{height:100%;margin:0;}

/* YOUR BOX */
#box{
  position: fixed;
  cursor: pointer;
  background-color: red;
  
  /* make the box full screen */
  width: 100vw; /* IE9+ */
  height:100vh; /* IE9+ */
  top: 0;
  left: 0;

  /* scale it down to 0.1 (10%) initially,
     make an offset from bottom left */
  -ms-transform: translate(50px, -50px) scale(0.1); /* IE9 */
  -ms-transform-origin: left bottom; /* IE9 */
  transform: translate(50px, -50px) scale(0.1);
  transform-origin: left bottom;

  /* smooth transition (IE10+) */
  -webkit-transition: all 0.7s ease;
          transition: all 0.7s ease;
}

/* ADD THIS CLASS WITH JS */
#box.fullScreen {
  /* Your override style:
     remove offset, scale it to 1 (100%) */
  -ms-transform: translate(0px, 0px) scale(1); /* IE9 */
  transform: translate(0px, 0px) scale(1);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>click the box</div>
<div id="box">your content</div>
