切换显示与JavaScript的div。开始隐藏，点击显示

我想切换是否可以使用按钮来隐藏/显示点击div。

I would like to toggle whether a div is visible using a button to hide/reveal the div on click.

我有这样做的代码，但div在默认情况下在页面加载时可见。我想让div开始隐藏，只有在观看者点击时才会显示。

I have code which will do this, but the div is visible on page load by default. I'd like the div to start hidden and only be revealed when the viewer clicks.

这是我目前使用的代码。有没有办法改变这种情况，因此div开始隐藏？

Here is the code I am using currently. Is there a way to change this so the div starts hidden?

<script>
function myFunction() {
    var x = document.getElementById('myDIV');
    if (x.style.display === 'none') {
        x.style.display = 'block';
    } else {
        x.style.display = 'none';
    }
}
</script>

<button onclick="myFunction()">Enquire Now &gt;</button>
<div id="myDIV">
    <form action="/post.php" method="post">
        <p>Enter your contact details</p>
        <p>
        Name: <input type="text" name="name"><br>
        Tel: <input type="tel" name="tel"><br>
        Email: <input type="email" name="email" value="Email Address"></p>

        <p><input type="submit"></p>
    </form>
</div>
