Question

我刚刚开始搞乱Boilerplate模板。我无法显示背景图像。

的CSS：

body {
font-size: 1em;
line-height: 1.4;
background-image: url (img/bg2.png);
background-repeat: no-repeat;

}

一些见解会被赞赏我几乎是一个业余爱好者

谢谢:)

Answer 1

您的链接周围没有括号

body {
font-size: 1em;
line-height: 1.4;
background-image: url ("img/bg2.png");
background-repeat: no-repeat;

}

Answer 2

出于某种原因，你似乎必须单独做这些，但这个小提琴有效：

CSS：

body {
    background-image: url('http://i.dailymail.co.uk/i/pix/2012/11/15/article-0-1609D0FF000005DC-373_964x641.jpg');
    background-repeat: no-repeat;
}

请看这个问题：

Background Image not working with HTML5 Boilerplate

在CSS中路径与自身的css文件相对。

css在哪里？在css文件夹中。包含图像的img文件夹在哪里？可能不在css文件夹中。

这意味着在你的css文件中你需要使用这样的路径：

url("../img/file.jpg);

这意味着“向上一级，找一个名为img的文件夹，进去，给我file.jpg。”

你的路径的方式意味着img文件夹在你的css文件夹中，可能不是这样。

Answer 4

从我在Firebug中可以看出，normalize.css现在正在覆盖背景。（第72行）

无法在Boilerplate模板中插入背景图像
