I'm trying to have an icon change color everytime an input box is hovered. The problem is it is only changing the background when hovering the first input textbox, not the other two.

I'm trying to get this effect without jquery.Thanks in advance for your help !

var input = document.querySelector ('input');
var icon = document.querySelector ('img');

input.addEventListener ('mouseover', function hover(){
  icon.style.background = '#D46855';
});
input.addEventListener ('mouseleave', function leave(){
  icon.style.background = '#81D455';
  
});

@import url('+Flower');


body{
 background-image :url(.565449774c2d4.png); 
}
h1{
 font-family: 'Indie Flower', cursive;
  font-size:3em;
  color:#D46855;
  letter-spacing:5px;
}

#container{
  text-align:center;
  margin:10% auto;
  padding-top: 50px;
  border-radius:15%;
  width:80%;
  height:400px;
  position:relative;
  background-color : rgba(84, 193, 212, 0.56);
 box-shadow: 5px 5px 4px 5px rgba(84, 193, 212, 0.56);
}

img{
left: 0;
right: 0;
bottom: 0;
margin: auto;
  height:100px;
  width : 100px;
  position:absolute;
  top: -95%;
  border-radius:30px;
  background:#81D455;
}

input{
  width:200px;
  height:15px;
  font-size:1.2em;
  padding:10px;
  text-align:center;
  display:flex;
  margin:0 auto;
  margin-top:20px;
}

<div id = 'container'>
  <h1>To Do List</h1>
  <img src = ".png">
  <form>
    
    <input type = 'text' placeholder = 'item' id = 'list' </input>
    <input type = 'text' placeholder = 'item' id = 'list' </input>
    <input type = 'text' placeholder = 'item' id = 'list' </input>

Any advice would be appreciated (:

• document.querySelector returns one single element, the first that matches the supplied selector - you need document.querySelectorAll and iterate through the result (disregard CSS solution) – Jaromanda X Commented Sep 29, 2017 at 3:22
• Well you only put an event listener on 1 of the inputs, you need to put the event on all of them, or use event delegation – Patrick Evans Commented Sep 29, 2017 at 3:22

querySelector returns only the first element that is found.

As you have multiple input elements use querySelectorAll

var input = document.querySelectorAll('input');

Also as querySelectorAll returns multiple elements ( which is a node list of inputs in this case ) , you will have to attach the event handlers in a loop.

var inputs = document.querySelectorAll('input');
var icon = document.querySelector('img');

inputs.forEach(function(input) {
  input.addEventListener('mouseover', function hover() {
    icon.style.background = '#D46855';
  });

  input.addEventListener('mouseleave', function leave() {
    icon.style.background = '#81D455';

  });
});
