This time I will show you how to use jQuery to implement a DIV that responds to the mouse sliding over and expand from bottom to top, and how to use jQuery to implement a DIV that responds to the mouse sliding over and expands from the bottom to the top. What are the precautions?, here is the actual combat Let’s take a look at the case.

2. Code

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery响应鼠标实现p由下向上展开</title>
<style type="text/css">
  .big{position:relative; width:234px; height:300px; background:#ccc}
  .show{position:absolute; display:none; bottom:0px;display:block; width:100%; height:auto; background:#f66 }
</style>
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
 {
  $(".big").hover(function () {
    $(".show").stop(true,true).animate({height:"70px"});
  }, function () {
    $(".show").stop(true,true).animate({height:"0px"});
  });
});
</script>
</head>
<body>
  <!--灰色的p-->
  <p class="big">
    <!--红色的p-->
    <p class="show"></p>
  </p>
</body>
</html>

Principle:

① First, the red p passesposition:absolute Absolute positioning , and through relative and bottom positioning, such as bottom:0px.
② The bottom positioning is fixed and expands upward when the height becomes higher.
③ Use jQuery’s $().animate() animation method to control the height change of the red p.
