Question

我在div上设置绝对位置，以便我可以在网页中心，一切都很顺利，直到我想为div加载一个轻微的fadeInDown。每当我在Y中翻译div时，它会在页面上对角线移动吗？

我有一种感觉，我将不得不重新制作整个东西，但使用display：table或display：flex？但在我改写页面之前，我只想要确认。

HTML：

<body>
    <div class="section">
        <div class="wrapper">
            <div class="content">
                <h2>Contact Me</h2>
                <form action="contactme.php" method="post" class="contact-form">
                    <div class="input-field">
                        <input type="text" name="name" required="">
                        <label for="">Full Name</label>
                    </div>

                    <div class="input-field">
                        <input type="text" name="cname" required="">
                        <label for="">Company Name</label>

                        <label for="">Current Website (N/A if None)</label>
                    </div>

                        <label for="">E-Mail</label>
                    </div>

                    <div class="input-field">
                        <textarea name="message" rows="5" required=""></textarea>
                        <label for="">Message</label>
