如何仅使用bootstrap的模态对话框,而不是整个bootstrap.css与我自己的css冲突

如果你担心输入或div等元素特定的css规则,那么只需重置css文件开头的所有内容.

谷歌CSS重置并发现：

article,section {
    display: block;

body {
    line-height: 1;
}
ol,ul {
    list-style: none;
}
blockquote,q {
    quotes: none;
}
blockquote:before,blockquote:after,q:before,q:after {
    content: '';
    content: none;
}
table {
    border-collapse: collapse;
    border-spacing: 0;
}

从那里你可以简单地定制一些东西,如文本/链接颜色和悬停等,但引导程序中的大部分CSS都与类一起使用,因此人们可以使用它自定义css.
