Question

所以我正在建立一个网站，教幼儿编程的概念。我发了一封电子邮件联系表格，因为我想让我的用户与我联系，因为他们对我的网站有任何改进的想法或问题。但是，我的很多语法都出现在网页上，我不知道为什么。我首先阅读了代码并发现了一些缺失的分号和'$'符号以及一个大括号。

尽管我检查了我的代码并修复了我的错误，但它仍然显示在我的网页上。我可能认为这可能与我的语法结构有关，但我并不是100％肯定。

这是我的代码：

<html>

 <title>CoderClub4Kids</title>
<style>
body {
    background-image: url("Background default.jpg");
    background-repeat: no-repeat;
    background-size: 100% 100vh;

.container {
    overflow: hidden;
    background-color: yellow;
    font-family: Arial;
}

.container a {
    float: left;
    font-size: 16px;
    color: black;
    text-align: center;
    padding: 14px 16px;

    font-family:Comic Sans MS;

    color: black;
    padding: 14px 16px;

    font-family: Comic Sans MS;
}

    display: none;
    position: absolute;
    background-color: #ffffcc;
    min-width: 160px;
    box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
    z-index: 1;
}

.dropdown-content a {

    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;
    text-align: left;
