我知道这真是草率但我对此有点新意。这是我的问题，当通过验证器运行时，我收到此错误

启动标记正文，但相同类型的元素已经打开。从第72行，第28栏;到第72行，第67栏

<li><a><p><br></p><body onload="greetings(); startTime()"><div id="txt"></div><div id="greeting"></div></a></li>

另外我被告知使用<center>来使图片居中是过时的，我应该使用CSS。但是，我有一个问题，因为我需要一些图片集中，其中一些不是。我怎样才能做到这一点，有些不是？

我该怎么做才能解决这个错误？

Answer 1

你有2个身体标签。将第1个替换为第2个，然后移除第2个。

将等级center添加到您的CSS中像这样的东西

img.center {
    display: block;
    margin-left: auto;
    margin-right: auto
}

并将该类放在要居中的图像标记上，然后删除中心标记。

<img src="assets/img/Spectre1.jpg" class="center" />
