Star Rating component fill all previous stars on hover

I am currently making a Star Rating component for our website, I use angular11 (should not matter I think), so far I have the rendering of the 5 stars depending on the current rating value and such, but I struggle to get the styling for the hovering correct.

Basicly for example if I have 2 out of 5 stars and I hover the 4th star the 3th should be filled too. I struggle to find the correct css to achieve that Thats what I got so far in CSS

.rating-icon-empty { fill: #9e9e9e }
.rating-icon { fill: #7C4DFF; margin-right: 5px; }
.editable .rating-icon-empty:hover { fill: #7C4DFF; cursor: pointer;}

My current CSS only fills the star that is hovered but not the previous unfilled stars.

Is there a way to achieve this with pure CSS or do I need to rely on hover listeners for each star?

It would be useful to have the HTML, with inline SVG, in your question. - Bo Frederiksen
See here: codepen.io/jamesbarnett/pen/vlpkh it works very well (I integrated it successfully). - Benny

I had your problem before, read these:

First Solution:

@import url(//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css);

fieldset, label { margin: 0; padding: 0; }
body{ margin: 20px; }
h1 { font-size: 1.5em; margin: 10px; }

/****** Style Star Rating Widget *****/

.rating { 
  border: none;
  float: left;
}

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

.rating > .half:before { 
  content: "\f089";
  position: absolute;
}

.rating > label { 
  color: #ddd; 
 float: right; 
}

/***** CSS Magic 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;  }
