我刚开始学习HTML和CSS,google建议的修复方法都没有成功地将我的联系人框对齐到页面的中心。我尝试过将内容对齐、项目对齐、内容对齐和显示灵活性与上面的东西结合起来。我的页面要么保持不变,要么联系人框自动对齐到左上角。
我有很多麻烦的东西,我已经建立了html到目前为止,从来没有对齐中心。我只是想了解为什么会发生这种情况。

我猜你只是打错了:
它应该如下所示:

你只需要把下面的css在css文件夹。当你开始写左上角是起点这就是为什么你的内容是去
html {文本对齐:居中}

请将“边距:35 px”带“填充:35 px”,并在contact-box类中使用以下4行将表单居中:
最高:50%;
左侧:50%;
位置:固定;
变换:平移(-50%,-50%);
附上更正后的代码供大家参考,希望对大家有所帮助!
