a：链接和a：访问不工作......？

Question

我的a：链接和a：CSS中的访问代码无效。我不确定为什么，这有点奇怪

此外，它实际上与我想要的相反。在访问之前，链接是紫色的，之后是相同的。

body {
  background-color: lightgoldenrodyellow;
  font-family: century gothic;
}
header {
  display: flex;
  justify-content: space-between;
  width: 100%;
  white-space: nowrap;
}
h1 {
  display: inline-block;
  font-size: 30px;
  text-decoration: underline;
}
nav {
  display: inline-block;
}
ul {
  color: black;
}
li {
  display: inline;
  font-size: 30px;
  margin-left: 10px;
  margin-right: 10px;
}
a:link {
  color: black;
}
a:visited {
  color: blueviolet;
}
footer {
  text-align: center;
  margin: 10px;
}
#image1,
#image2 {
  border-radius: 6px;
  display: block;
  margin: auto;
  margin-bottom: 80px;
  width: 70%;
}
p {
  text-align-last: center;
  font-family: helvetica, lucida grande, sans-serif;
  font-size: 30px;
}

Answer 1

被访问的选择器匹配其href链接已经访问过的所有元素。

您需要设置不同的href

<nav>
  <ul>
    <li><a href="https://www.google.co.in/">Home</a></li>
    <li><a href="about.html">About</a></li>
    <li><a href="blog.html">Blog</a></li>
    <li><a href="event.html">Event</a></li>
    <li><a href="galery.html">Gallery</a></li>
    <li><a href="contact.html">Contact</a></li>
  </ul>
</nav>
