问题描述
尝试设置某些样式,但类选择器为。不起作用,但是如果我使用id选择器#,则可以起作用
Trying to set some styles but class selector "." is not working, but if I use id selector "#" it works
此处的代码
<style>
.activeOption{
color: #fff;
background: rgba(255,255,255,0.2);
text-decoration: none;
}
</style>
<li ><a id="" class="activeOption" href="#" onclick="Javascript : console.log('sisas')">Datos del Cliente</a></li>
问题是我想对许多支持者使用这种样式,因此不会使用id选择器
the thing is that I wanna use that style for many comoponents so id selector is not apropiated
感谢有人能帮助我
推荐答案
该屏幕截图表示,由于特殊性。
What that screenshot is saying is that other styles are overriding this style due to specificity.
解决特异性问题的最佳方法是降低覆盖它的选择器的特异性。不过,这并非总是可能的,因此,万不得已时,您可以通过将类链接到自己来提高特异性。
The best way to solve specificity issues is to decrease the specificity of the selectors overriding it. That isn't always possible though, so as a last resort you can increase your specificity by chaining classes to themselves.
.activeOption.activeOption {
[styles]
}
您可以链接多次根据需要,链越多,它覆盖的特异性就越强。请注意,如果尝试覆盖ID,则此方法无效,因为它需要255个链。重构ID是我的建议。
You can chain as many times as needed, the more chains the more specificity it overrides. Note that if trying to override an ID this method doesn't work as it requires 255 chains. Refactor the ID is my advice here.
