I'm trying to get all the divs within a div with document.querySelectorAll. Interestingly, when I set in the JS the height to 1000, the explorer's scroller enlarges accordingly (only the balloon doesn't get bigger). What am I doing wrong?
'use strict';
var gElBalloons;
function init() {
gElBalloons = document.querySelectorAll('.balloons');
setInterval(moveBalloons, 1000);
}
function moveBalloons() {
for (var i = 0; i < gElBalloons.length; i++) {
gElBalloons[i].style.height = 1000 + 'px';
}
}
body {
margin: 10%;
}
.balloon-1 {
display: block;
width: 120px;
height: 145px;
background-color: red;
border-radius: 80%;
position: absolute;
}
.balloon-2 {
display: block;
width: 120px;
height: 145px;
background-color: blue;
border-radius: 80%;
left: 40%;
position: absolute;
}

For now, I just want to test and make sure it works correctly.
It seems that your selector selected the wrong div. If you want to make the ball bigger, you should select balloon-1 and balloon-2 instead of their container balloons.
'use strict';
var gElBalloons;
function init() {
gElBalloons = document.querySelectorAll('.balloons > div');
setInterval(moveBalloons, 1000);
}
function moveBalloons() {
for (var i = 0; i < gElBalloons.length; i++) {
gElBalloons[i].style.height = 1000 + 'px';
}
}
body {
margin: 10%;
}
.balloon-1 {
display: block;
width: 120px;
height: 145px;
background-color: red;
border-radius: 80%;
position: absolute;
}
.balloon-2 {
display: block;
width: 120px;
height: 145px;
background-color: blue;
border-radius: 80%;
left: 40%;
position: absolute;
}
