昨天我发布了一个问题，有些人回复得非常好。但是我已经尝试了你所说的一切，似乎没有任何工作。
如果我给图像一个宽度，但只有当宽度小于实际的一个（500px）时，它才有用。我的形象比那个大。我试图改变图像的宽度（在图像中添加一个类，然后在css中指定图像的宽度，仍然无法正常工作，甚至在分号前写作！重要）
我要粘贴整个＆＃34;＆＃34;网站＆＃34; （这是一个简单的单页简历）代码，这样你就可以更清楚地看到可能出错的地方。
我希望图像居中并保持原始尺寸：

只需在图像中设置100％的宽度即可。它将自动适应父宽度。

感谢所有人。
我想回答一下我最后做了什么，以防将来帮助别人。
老师/班级说＆＃34;包装＆＃34; p中的图像跟随@Fabian Lurtz的adice改变了p为div。
然后在css中，关注@Alvin Pascoe的建议：http://bit.ly/1OniMMl
我补充说：
.div {
display: block;
margin-left: auto;
margin-right: auto;
}
如果我的网站＆＃34;会有更多的div我可以设置一个类或id
希望它有所帮助。再次感谢所有人！

如果您想将宽度设置为100％，只需将宽度设置为 -
max-width: 100%
