Change all navigations links on hover of one - html

Question

I'm trying to replica the navigation menu from this website. I've managed to it working to a certain extent, but can't make the service link when hovered to stay the same colour and all of the other to change.
.header {
display: flex;
width: 100%;
}
.nav {
width: 80%;
margin: auto;
position: relative;
}
.nav a {
color: #000;
}
.nav ul {
list-style: none;
padding: 0;
width: fit-content;
}
.nav ul:hover a{
color: #eee !important;
padding-bottom: 20px;
}
.nav ul li:hover a {
color: #333;
padding-bottom: 20px;
}
.nav li:last-child {
margin: 0;
}
.nav ul li {
display: inline-block;
margin: 0 35px 0 0;
}
.three:hover>.sub-menu {
display: flex;
opacity: 1
}
.sub-menu {
height: 200px;
display: flex;
flex-direction: row;
position: absolute;
top: 100%;
background: #333;
display: none;
opacity: 0;
left: 0;
right: 0;
}
<div class="header">
<div class="nav">
<ul>
<li>
<a class="one">Home</a>
</li>
<li>
<a class="two">About</a>
</li>
<li class="three">
<a class="">Services</a>
<div class="sub-menu">
<div class="col-1-4"></div>
</div>
</li>
<li>
<a class="four">Contact</a>
</li>
</ul>
</div>
</div>
As you can see I've changed the link colours on hover of the unordered list which is probably not the best way of trying to get this to work. Please, could someone advise me on the best method to fix this?

You're close -- you have to remove the !important from the rule affecting .nav ul:hover a as this is overriding the rule that will ensure the hovered item is a different color than the rest:
.header {
display: flex;
width: 100%;
}
.nav {
width: 80%;
margin: auto;
position: relative;
}
.nav a {
color: #000;
}
.nav ul {
list-style: none;
padding: 0;
width: fit-content;
}
.nav ul:hover a{
color: #eee;
padding-bottom: 20px;
}
.nav ul li:hover a {
color: #333;
padding-bottom: 20px;
}
.nav li:last-child {
margin: 0;
}
.nav ul li {
display: inline-block;
margin: 0 35px 0 0;
}
.three:hover>.sub-menu {
display: flex;
opacity: 1
}
.sub-menu {
height: 200px;
display: flex;
flex-direction: row;
position: absolute;
top: 100%;
background: #333;
display: none;
opacity: 0;
left: 0;
right: 0;
}
<div class="header">
<div class="nav">
<ul>
<li>
<a class="one">Home</a>
</li>
<li>
<a class="two">About</a>
</li>
<li class="three">
<a class="">Services</a>
<div class="sub-menu">
<div class="col-1-4"></div>
</div>
</li>
<li>
<a class="four">Contact</a>
</li>
</ul>
</div>
</div>
Here's a good resource on how !important affects other rules on the page.
