Question

班级.content的背景图片不起作用。 PS：等待10秒以使预加载器淡出。

如何设置文件夹：
enter image description here

Answer 1

你的道路是错的。您的css文件与图片不在同一文件夹中，因此您无法使用background-image: url(noisy-texture-100x100-o5-d20-c-333333-t0.png);。请改用以下内容：

background-image: url("../noisy-texture-100x100-o5-d20-c-333333-t0.png");

这将上升1个文件夹。 url()属性是相对于.css文件计算的，而不是.html文件。

Answer 2

将../放在网址路径

之前

background-image: url(noisy-texture-100x100-o5-d20-c-333333-t0.png);。

所以，它应该看起来像

background-image: url('../noisy-texture-100x100-o5-d20-c-333333-t0.png');

Answer 3

background-image: url("../noisy-texture-100x100-o5-d20-c-333333-t0.png");

尝试这样

编辑：如上所述，你的道路是错误的。在url(之后你忘记了＆＃39; ../并在最后＃39;）（你忘记了引用）

我的背景图片不起作用
