html - 无法设置表单提交按钮的样式

Question

编辑:已解决，看评论!

我读过几篇关于在表单中设置提交按钮样式的帖子，但它似乎只部分适用于我。我可以更改边框，但不能更改背景颜色或字体设置。有人可以告诉我我的代码有什么问题吗？我是表格的新手，所以我可以只使用 n00bed。我试过背景、背景颜色、十六进制值……我只是被难住了。

#submitButton {
color: black;
background: #cac9c9;
border: 4px solid blue;

<form action="#" method="post">
    <input type="text" value="user@domain.com" />
    <div class="clear"></div>
    <hr />
    <div id="checkboxContainer">
        <span>Select the newsletters you'd like to receive</span>
        <input type="checkbox" name="travel" value="Getaways" />
        <label>Destinations &#38; Getaways</label>
        <br />
        <input type="checkbox" name="travel" value="Tips" />
        <label>Weekly Travel Tips</label>
    </div>
    <input id="submitButton" type="submit" value="SIGN UP" />
</form>
