我的 CSS 有问题。

这是我的 html:

<nav id="navigation">
<ul>
<li>
<a class="navbtn" href="?page=contact">
<img src="images\navigation\icons\contact.svg" width="25px">
<p>contact</p>
</a>
</li>
</ul>
</nav>

这是我的CSS:

#navigation ul:nth-child(1) li a:hover {
text-shadow: 0px 0px 20px black;
opacity: 1.0;

}

.iconopacity {
fill-opacity: 0.3;
}

.iconopacity:hover {
pointer-events: all;
fill-opacity: 0.7 !important;
}

这是我的 svg 文件:

我用 illustrator 制作了图标。当鼠标悬停在图标上时,我想通过降低透明度来使图标更暗一点。我试过:

.iconopacity:hover {
fill-opacity: 0.7;
}

但是没有用。我还尝试了一些其他的 css 选择器,比如:

  #navigation ul:nth-child(1) li a:hover .iconopacity { css here }

但是也没用。

我认为我在将鼠标悬停在链接上时选择了错误的 css 路径,但问题也可能是完全不同的。

我认为这个问题也可以通过使用 javascript 来解决,但我不喜欢 javascript,我认为应该可以使用 css 来解决。

请帮帮我好吗? :)

最佳答案

你不能改变 svg 的不透明度,但你可以做的是改变父元素的不透明度,你会得到同样的效果
