我目前正在开发一款货币转换器应用程序,并尝试为货币添加旗帜图标。我正在使用 SelectBoxIt jQuery 插件来做到这一点。

问题是每当我使用 SelectBoxIt 插件时,选择选项下拉样式会发生冲突,请参见下文。

查看选项如何水平折叠

See how the options collapse horizontally

令人惊讶的是,如果我删除指向我的 CSS 文件的链接,插件会神奇地工作。

知道如何解决这个问题吗?

最佳答案

css 经常会发生冲突。每当发生这种情况时,您都有几个选择,尽管它们都等于同一件事:比糟糕的 css 更强大。

做到这一点的最好方法是更具体:

span {
display: inline-block;
background: red;
height: 30px;
width: 30px;
}

div span {
background: blue;
}

div > span {
background: green;
}
<span></span>

<div>
<h1><span></span></h1>
<span></span>
</div>

在上面的例子中,span 是最不具体的,div span 是比较具体的,div > span 是最具体的。弄清楚有问题的 css 有多具体,并且比它更具体。

或者,使用 !important,但确实不建议这样做。
