我只是想知道为什么当我点击联系人meRegister.php时，下面的文本会发生变化

其他页面应该是这样的

他们都有相同的css脚本写在下面 style.css

h1{color:yellow;}
h2{color: yellow;}
body{outline-style: dotted;outline-color: yellow;}
.r{font-family: verdana}
body {background-image: url("c.jpg");}

.1{border-radius: 20%;}


ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    overflow: hidden;
    background-color: rgba(255,255,255,0.5);

}

样式表style2.css将主体字体设置为字体系列：Courier New、Courier、monospace；样式表style.css不设置主体字体

这就是为什么它们有不同的字体。要修复它，请添加字体系列：Courier New、Courier、monospace；添加到style.css中的主体样式，或从style2.css中删除该样式，具体取决于您需要的字体。

您可以提供more.php或mypage.php的代码吗？另外，您正在链接第二个css表style2.css，请检查是否也可以使用将css文件包含在HTML中，您可以发布links.php的代码吗？@Blinkydamo添加
