When hovering over child, change css of parent

Question

I want to change the css of the parent on hover of the Child element.

<ul id="main-menu">
        <li>
            <a href="#">
                <i class="fa fa-building-o" aria-hidden="true"></i>
                Private Limited
                <i class="fa fa-caret-down"></i>
            </a>
            <ul class="submenu">
                <li><a href="#0">Company</a></li>
                <li><a href="#0">Contact</a></li>
                <li><a href="#0">Industry</a></li>
            </ul>
        </li></ ul>

What I want is if I am on a submenu , li of the main menu will be highlighted.

Answer 1

As already mentioned, the parent selector does not exist, but if you acknowledge that you are already above the parent, you can achieve what you want.

Example:

#main-menu > li:hover > a
{
  background-color: #F00;
}

#main-menu >  li > .submenu > li:hover
{
  background-color:#00F;
}

<ul id="main-menu">
  <li>
    <a href="#">
      <i class="fa fa-building-o" aria-hidden="true"></i>
      Private Limited
      <i class="fa fa-caret-down"></i>
    </a>
    <ul class="submenu">
      <li><a href="#0">Company</a>
      </li>
      <li><a href="#0">Contact</a>
      </li>
      <li><a href="#0">Industry</a>
      </li>
    </ul>
  </li>
  </ ul>

Like other posts, there is no parent selector.

Here's how it should work:

li:has(> i:hover) { /* styles to apply to the li tag */ }

, , li i :hover. css. , .

There is currently no way to select the parent element of an element in CSS.

Answer 4

Here you can go ..

For Apply CSS..

$("#main-menu li").mouseover(function()
{ 
      $("#main-menu a:eq(0)").css({'color':'blue','font-weight':'bold'});
});

For Remove CSS..

$("#main-menu li").mouseout(function()
{ 
     $("#main-menu a:eq(0)").removeAttr("style");
});

If you want to call a child with a child, use this.

.triggerDiv{
  display:none;
}
.child:hover ~.triggerDiv {
  display:block
}

<div class="main">
  <div class="parent">
    <div class="child">
      <p>Hello</p>
    </div>
    <div class="triggerDiv">
      <p>I'm Here</p>
    </div>
  </div>
</div>
