我正在尝试将背景颜色更改为黑色。但它不起作用。 我提供的 .css 引用链接有问题吗？背景图片效果很好，但是当我只想制作一个具有特定颜色的普通背景时，它总是显示白色。
我什至尝试添加 !important, "background-color: black !important;...但仍然没有用。

</html>最佳答案
您在 CSS 中使用的是 ID，而不是在 html 中使用的类
违规代码
#home{
padding-top:50px;
height:667px;
background-color:black;
}
更正代码
.home{
padding-top:50px;
height:667px;
background-color:black;
}
关于html - 无法更改背景颜色，用于 Bootstrap ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36601831/
