Replace your code with the following and it will work as you desire. 用以下代码替换您的代码，它将按您期望的方式工作。

  $(document).ready(function () { $('.wrapper h1').addClass('load'); });

 .wrapper { position: relative; } h1 { opacity:0; color:black; font-size: 21px; text-align: center; transition: opacity 1s ease-in; } .load { opacity: 1; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div class="wrapper"> <h1>SWEGRE DESIGNS</h1> </div>
