英文:
it doesn't work when i hover my li's in my navbar
问题
当我克隆劳力士（Rolex）网站以提升自己时，当我悬停在导航栏中的li元素上时，我想要同时改变我的SVG图标和超链接（a标签）的颜色，但它没有生效。
我尝试了以下方式：
.nav-links li:hover {
color: red;
}
但它没有生效。请帮我，为什么它不起作用？
英文:
when i clone rolex website to improve myself, when i hover over the li's in my navigation bar i want the color of both my svgs and a tags to change but it's not working;

答案1
得分: 1
这是要翻译的代码部分：
- 这个目标是
li元素。
.nav-links li:hover{
color: red; /*它不起作用，我尝试过了*/
}
- 想要改变我的两个 SVG 的颜色。
color 在 SVG 上不起作用。您需要针对更具体的元素（如 path）并使用实际影响它的属性（如 fill）。
- 以及要更改的
a标签，但它不起作用；
您已经为 a 元素指定了它们自己的颜色：
#nav-bar .nav-links li a {
color: #fefefe;
}
即使您没有这样做，a 元素默认也有自己的颜色。
它们不会从 li 继承。
再次强调，您需要针对 a 元素本身进行目标，而不是 li。
英文:
This targets the li element.
> .nav-links li:hover{
> color: red; /it doesnt work, i tried it/
> }
> want the color of both my svgs
color doesn't do anything on an SVG. You need to target a more specific element (like the path) and use a propertiy that actually affects it (like fill.
> and a tags to change but it's not working;
You gave the a elements their own color:
> #nav-bar .nav-links li a {
> color: #fefefe;
Even if you didn't, a elements have their own colour by default.
They aren't going to inherit from the the li.
Again, you need to target the a element itself, not the li.

以下是您要翻译的内容：
"Quentin" 和 "iorgv" 指出：
SVG 元素不会自动继承父元素的 color 值，而是期望继承 fill 属性的值。
然而，您可以通过应用 fill: currentColor 值来简化您的 CSS 规则，如下所示：
svg path {
fill: currentColor;
}
关键是要避免对 <svg> 或 <path> 元素应用特定的填充样式。
将 svg 图标包装在您的 <a> 元素内也可以简化 CSS 规则。
英文:
As pointed out by Quentin and iorgv:
svg elements wont't automatically inherit the parent's color value but expect a fill property value instead.
However, you can simplify your css rules by applying a fill: currentColor value like so
svg path{
fill: currentColor;
}
It's crucial to avoid specific fill styles applied to the <svg> or <path> element.

It's because you have to address the a separately, and the fill color must be defined for the svg too, and only fill color can be changed for the svg.
