我是这些语言的新手，我仍然有一些难以吸收的东西，对我来说，我会更改我在互联网上找到的代码示例。
现在我的项目有两个困难。
1我有一个小空白，我看不到它在代码中的位置。
2生成的页面的宽度大于浏览器页面的宽度。

答案 0 :(得分：2)
您为元素 #main 提供100％的宽度以及填充，使得该框总共（100％+总水平填充）宽。如果你想在一个盒子里添加填充而不改变它的大小，请添加：box-sizing：border-box。
答案 1 :(得分：0)
尝试将您的css更改为：
* {
margin: 0;
padding: 0;
}
html,body {
font-family: Verdana, "DejaVu Sans", "Bitstream Vera Sans", "Lucida Sans", Arial, Helvetica, sans-serif;
font-size: 90%; /* Allow IE/Win to resize the document */
color: black;
background: white;
border: none;
width: 100%;
height: 100%;
}
某些浏览器（如Google Chrome）具有预定义的边距和填充。 *符号选择文档中的所有内容，使用*你可以摆脱那些讨厌的预定义边距和填充。
此外，我已将主体和html标签的宽度和高度更改为拉伸至屏幕尺寸的100％。

用此将代码从 更改为 。希望它有所帮助
答案 3 :(得分：0)
这是由于#main
中的填充#main{
background: none repeat scroll 0 0 rgb(255, 255, 255);
border-left: 1px solid rgb(153, 153, 153);
color: rgb(0, 0, 0);
line-height: 1.5;
margin: 0 0 0 12.5em;
/* padding: 0.1em 1.5em 0.5em 1em;*/
text-align: justify;
width: 100%;
}
删除#main中的填充，它应该可以工作。
