    <meta charset="UTF-8">
    <title>Animated Background using HTML and CSS | No Javascript</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <div class="wrapper">

        transform: translateY(800px) rotate(360deg);
        opacity: 0;
    }
}

but my window view does not change. Please help me!

Edit whatThis->Source

You mean you are adding HTML & CSS to "what's this" control, to help users see how to use a certain part of your application?

In such case, it won't work. Qt's rich text widgets only support a limited subset of HTML4 and a few basic CSS commands.
