CSS change body background-color on button hover?

It's not possbile in CSS. In JavaScript it's quite easy, you're looking for onmouseover/out events.

var button = document.getElementById('hover');

var body = document.body;

button.onmouseover = function() {

 body.className = 'hovered';

}

button.onmouseout = function() {

 body.className = '';

}

body {background: #000;}

body.hovered {background: #ff0;}

<button id="hover">button</button>

Change body background color on hover

$(document).ready(function(){

$('img').mouseover(function(){

  $('body').css('background-color',$(this).data('color'));

});

});

Changing body background when hovering over a link

What you want to do is actually not possible with CSS as you are asking if there is a parent selector BUT we can use some workarounds.

Here is an idea where I use a pseudo element from the a that I make it to cover the whole body and it behaves as the background of the body:

a {

  color: white;

  text-decoration: none;

}

a:before {

  content: "";

  position: fixed;

  top: 0;

  right: 0;

  left: 0;

  bottom: 0;

  background: #000;

  z-index: -1;

  pointer-events:none;

}

a:hover::before {

  background: red;

}

<a href="#">link</a>

div background color, to change onhover

The "a:hover" literally tells the browser to change the properties for the <a>-tag, when the mouse is hovered over it. What you perhaps meant was "the div:hover" instead, which would trigger when the div was chosen.

Just to make sure, if you want to change only one particular div, give it an id ("<div id='something'>") and use the CSS "#something:hover {...}" instead. If you want to edit a group of divs, make them into a class ("<div class='else'>") and use the CSS ".else {...}" in this case (note the period before the class' name!)

Using CSS only: change a div's background color on hover

You should put the <a> inside the <div>. If you want it to stretch across the full space, add display: block to its style.

<div id="rentalAnnc">
    <a class="sidebarLink" href="facilitiesForHire.html">
        <p>We have a range of Education Facilities available for lease and hire</p>
    </a>
</div>

a.sidebarLink { color: #000000; text-decoration: none; display: block; }
a.sidebarLink:hover { background-color: blue; }

div hover background-color change?

.e:hover{
   background-color:#FF0000;
}

Can I change the background-colour of an element, when hovering over another?

Using pure CSS: Add a tilde character in between the hover and target element to identify the effected element you wish to change on hover. In CSS, the symbol tilde(~) is know as Subsequent-sibling combinator.

MDN General sibling combinator

#cont {
  display: flex;
  justify-content: space-around;
}

.el1 {
  height: 200px;
  width: 200px;
  background: #eee;
}

.el2 {
  height: 200px;
  width: 200px;
  background: #ff0;
}

.el1:hover~.el2 {
  background: #f00;
  color: #fff;
}

<div id="cont">
  <div class="el1"></div>
  <div class="el2"></div>
</div>
