我网页中的所有内容与浏览器边缘之间的距离都很小。我必须添加一些执行此操作的代码，但是不确定执行了什么操作。我该怎么做才能删除它？同样在我的导航栏中，右侧的最后一个链接有一个很小的间隙，在其右侧边缘的悬停上没有突出显示。
我还需要有关导航栏+标头和侧面横幅之间的空隙的帮助。我如何消除差距？

忽略css中的.headers_t id，我现在正在编辑...除非是原因。

最佳答案
您需要在正文CSS中添加margin:0px和padding:0px
所以：
.body{
background-color: #61B329;
height: 50%;
color: #FFFFFF;
margin:0px;
padding:0px;
}
