Change star rating on hover

Question

I use this code to display stars:

Answer 1

This can almost work with pure CSS. It does need one line of JavaScript to set the initial value though:

document.getElementById('Degelijkheid-1-5').checked = true;

.rating input {
    display: none;
}
.rating label:before {
    margin: 5px;
    font-size: 1.25em;
    font-family: FontAwesome;
    display: inline-block;
    content:"\f005";
}
li {
    list-style:none;
}

.ratingSelector input + label {
    color: #FFD700;
}
.ratingSelector input:checked ~ input:not(:checked) ~ label {
    color: #ffffd;
}
.ratingSelector input:checked ~ input:not(:checked) + label:hover ~ label {
    color: #ffffd;
}
.ratingSelector:hover input + label,
.ratingSelector:hover input:checked + label {
    color: #FFED85;
}
.ratingSelector:hover input:checked ~ input:not(:checked) ~ label:hover,
.ratingSelector:hover input:checked ~ input:not(:checked) + label {
    color: #FFD700;
}
.ratingSelector:hover input:checked ~ input:not(:checked) ~ label:hover ~ label {
    color: #ffffd !important;
}
.ratingSelector input + label:hover ~ label {
    color: #ffffd !important;
}

<ul class="rating">
    <li> <span class="ratingSelector">
    <input type="radio" name="ratings[1]" id="Degelijkheid-1-5" value="1" class="radio"/>
<label class="full" for="Degelijkheid-1-5"></label>
    <input type="radio" name="ratings[1]" id="Degelijkheid-2-5" value="2" class="radio"/>
<label class="full" for="Degelijkheid-2-5"></label>
    <input type="radio" name="ratings[1]" id="Degelijkheid-3-5" value="3" class="radio"/>
<label class="full" for="Degelijkheid-3-5"></label>
    <input type="radio" name="ratings[1]" id="Degelijkheid-4-5" value="4" class="radio"/>
<label class="full" for="Degelijkheid-4-5"></label>
    <input type="radio" name="ratings[1]" id="Degelijkheid-5-5" value="5" class="radio"/>
<label class="full" for="Degelijkheid-5-5"></label>
    </span>
    </li>
</ul>

EDIT

To use JS (to re-order the items):

var objGroup = document.getElementsByClassName('ratingSelector');
for (var i = 0; i < objGroup.length; i++) {
  var objRadio = [].slice.call(objGroup[i].getElementsByClassName('full')); // Create an array of items
  for (var j = objRadio.length; j--;) { // Loop through the array backwards
    var checkbox = document.getElementById(objRadio[j].getAttribute('for'));
    objGroup[i].appendChild(checkbox);
    objGroup[i].appendChild(objRadio[j]);
  }
}

.rating {
  direction: rtl;
  text-align: left;
}
.rating input {
  display: none;
}
.rating label:before {
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}
li {
  list-style: none;
}
.rating label {
  color: #ffffd;
}

Answer 2

As stated in previous answers, CSS selectors work only in the netural order of the DOM. (Even though this can change some time in the future).

So, if you can not change your DOM, you need to reverse your CSS logic:

Change all the elements on hover of the container. And then use the sibling selector to change the elements to the right of the hovered item

.rating input { display: none; } 
.rating label:before { 
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}

li {list-style:none; }

/***** CSS to Highlight Stars on Hover *****/

.rating label {color: grey;}
label:hover { color: red;  }
.ratingSelector:hover .full {color: red; }
.full:hover ~ .full { color: grey !important;  } 

<ul class="rating">
<li>
<span class="ratingSelector">
<input type="radio" name="ratings[1]" id="Degelijkheid-1-5" value="1" class="radio">
<label class="full" for="Degelijkheid-1-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-2-5" value="2" class="radio">
<label class="full" for="Degelijkheid-2-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-3-5" value="3" class="radio">
<label class="full" for="Degelijkheid-3-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-4-5" value="4" class="radio">
<label class="full" for="Degelijkheid-4-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-5-5" value="5" class="radio">
<label class="full" for="Degelijkheid-5-5"></label>
</span>
</li>
</ul>

Answer 3

Just add the below CSS code to make it from left to right:

.ratingSelector {
    max-width: 145px;
    display: inline-block;
}
.rating label {
    float: right;
}

Answer 4

You expected thing is possible with only css. Because css rule is applied for next sibling not for previous. You should also use JQuery.

But you can do it using following trick using css:

.rating input { display: none; } 
.rating label:before { 
  margin: 5px;
  font-size: 1.25em;
  font-family: FontAwesome;
  display: inline-block;
  content: "\f005";
}

li {list-style:none;
direction:rtl;
text-align: left;}

.rating label { 
  color: #ffffd;
}

/***** CSS to Highlight Stars on Hover *****/

.rating input:checked ~ label, /* show gold star when clicked */
.rating:not(:checked) label:hover, /* hover current star */
.rating:not(:checked) label:hover ~ label { color: #FFD700;  } /* hover previous stars in list */

.rating input:checked + label:hover, /* hover current star when changing rating */
.rating input:checked ~ label:hover,
.rating label:hover ~ input:checked ~ label, /* lighten current selection */
.rating input:checked ~ label:hover ~ label { color: #FFED85;  } 

<ul class="rating">
<li>
<span class="ratingSelector">
<input type="radio" name="ratings[1]" id="Degelijkheid-5-5" value="5" class="radio">
<label class="full" for="Degelijkheid-5-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-4-5" value="4" class="radio">
<label class="full" for="Degelijkheid-4-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-3-5" value="3" class="radio">
<label class="full" for="Degelijkheid-3-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-2-5" value="2" class="radio">
<label class="full" for="Degelijkheid-2-5"></label>
<input type="radio" name="ratings[1]" id="Degelijkheid-1-5" value="1" class="radio">
<label class="full" for="Degelijkheid-1-5"></label>
</span>
</li>
</ul>
