为什么会出现在我的网站，甚至与宽度的边缘设置为100％的差距呢？

Question

更新：我已经囊括了所有的我的代码。我有我的设置为100％的身体和背景图片的宽度和我身边有我的页面周边的空白。我试着用百分比，边距和填充，没有什么打到目前为止的工作。我有一个背景图像是黑色，所以它是非常明显的。

下面是我的一些CSS的：

 body {
  background: url("background.png") no-repeat fixed center;
  background-size: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
 }

 #msg {
  color: #000000;
  font-size: 40px;
  margin: 0 auto;
  padding-top: 400px;
  padding-right: 50px;
  float: right;
  font-family: "Roboto Mono", monospace;
}

header {
  width: 100%;

Answer 1

事情是浏览器有一些默认的CSS设置。定义你自己的样子:)当心，你重新定义之前，一切都将是那么无样式的前谷歌搜索词组“重置CSS”，并将其纳入

Answer 2

尝试设置背景图片的属性...

background-size : cover;

我这样认为，从这个属性您的问题将得到解决。

Answer 3

它是在你的页面添加默认余量基本的东西。对于防爆：Click to see the Default margin

所以，你需要删除。所以，你必须添加的样式在你的风格标签<style>body {margin:0px;}>你可以根据你的需要添加额外的样式。

<html>
<head>
<style>
.img
{
width:100%;
height:100%;
}
body
{
margin:0px;
}
</style>
</head>
<body>
<image src="https://4.img-dpreview.com/files/p/E~TS590x0~articles/3925134721/0266554465.jpeg" class="img">
</body>
</html>

希望它会帮助你。谢谢。

Answer 4

好吧，我不知道你的HTML结构，所以我的建议，我主要使用的东西，

<head>
#..
</head>

<body style="margin: 0;">

    <img class="background">

</body>

<style>
 .background{
    width: 100%;
    height: ..
    ..
  }
</style>

我要做的就是让身体，整个屏幕。边距设置为0，使其100％的屏幕尺寸没有留下更多的空间。

然后，我添加的，而不是直接添加背景图片body标签里面我的头格或背景图片或页脚。你可以让所有的这些100％或任何你的要求。不会有关于保证金的任何问题。

这是我使用，在大多数情况下，我工作得很好。希望这可以帮助你。
