I want soundbar effects i.e
I want the corresponding divs(bars) to increase/decrease height indefinetely like in the code snippet below. I want to acheive the same effect in Vanilla JS.
I want them to change height randomly i.e 5 bars will change height in 5 random ways.
The Element.animate() method is not doing the job and I am not allowed to use any external libraries or API's as well. I am unsure of using the CSS animate method.
The code written below is in jQuery. I am unable to decipher the same solution in Vanilla JS.
function fluctuate(bar) {
var amplitude = Math.random() * 42;
console.log(amplitude);
var height = amplitude * 4;
//Animate the equalizer bar repeatedly
bar.animate({
height: height
}, 1000, function() {
fluctuate($(this));
});
}
$(".bar").each(function(i) {
fluctuate($(this));
console.log($(this));
});

margin-right: -4px;

Im trying to hide the bottom of the girl image when the 3D background is triggered. I tried to add the overflow: hidden; to the test-imgplace class and it doesn't look right.
Is there a better way to fix it?

I have a timeline like this. But if there are a lot of points, it does not look very nice. How can I add functionality like a slider? To be displayed (only the first 5 years) and the rest to appear after the transition between years.
How can i do this? Or maybe there are some libraries with such functionality.
function initProgress() {
var activeDist = $(".slide a.active").position();
activeDist = activeDist.left;
$(".after").stop().animate({
width: activeDist + "px"
});
}
initProgress();
$("a").click(function(e) {
e.preventDefault();
$(".slide a").removeClass("active");
$(this).addClass("active");
initProgress();
});
$(window).resize(function() {
initProgress();
});

I need to know how to make the text appear as the div floating_mask grows.
right now the text while growing the div the text is put in two lines when the translation ends as the div is already at 100% if it stays as it has to be.

JAVASCRIPT
<script type="text/javascript">
document.getElementById('section2').onclick = function(){
$('.one').css('right','100%');
$('.two').css('right','auto');
}
document.getElementById('section3').onclick = function(){
$('.two').css('right','100%');

function addVisit(){
var progressTag = $('#myBar');
count ++;
progressTag.css('width', count * 10 + "%");
});
</script>
Your main issue is that the count variable has not been created and given a value initially.
I have optimized your code a bit and this is how I did it:
var count = 1;
$(document).ready(function() {
$("#section2, #section3, #section4").click(function() {
$('#myBar').css('width', ++count * 10 + "%");
});
});
I also added transition: all 1s; for animated CSS transition.
Here is your updated code in JSFiddle
I have the following page and I am using a JavaScript with jQuery to control the animations. However, the current code toggles all animations when the page is loaded. What I want to do is toggle the animation, when the parent div of the element is visible in the viewport. So my first thought was 'registering' the .half-width as allModifications, but this would exclude the last list.
Can someone help me and give me a best practice on which element I should register this 'listener', so that each element gets toggled seperately?
Little example: When the first list gets 'visible', it should be animated by the script. The second list should not be animated, first when it gets visible too.
//this is only to make the scroll arrow work
$(document).on('click', 'a[href^="#"]', function (event) {
//prevent direct jump to the linked element
event.preventDefault();
$('html, body').animate({
scrollTop: $($.attr(this, 'href')).offset().top
}, 500);
});
//this function determines wether an element is visible on the current viewport or not
(function($) {
$.fn.visible = function(partial) {
var $t = $(this),
$w = $(window),
viewTop = $w.scrollTop(),
viewBottom = viewTop + $w.height(),
_top = $t.offset().top,
_bottom = _top + $t.height(),
compareTop = partial === true ? _bottom : _top,
compareBottom = partial === true ? _top : _bottom;
return ((compareBottom <= viewBottom) && (compareTop >= viewTop));
};
})(jQuery);
var win = $(window);
var allModifications = $(".container");
//make elements visible that get scrolled into the viewport
win.scroll(function(event) {
var current = 1;
var current2 = 1;
allModifications.each(function(i, el) {
var el = $(el);
if (el.visible(true)) {
el.find(".half-width-text").addClass("open");
el.find(".list-div ul li").each(function(){
$(this).addClass("animate").css("animation-delay", current + 's');
current++;
});
el.find(".list-div2 ul li").each(function(){
$(this).addClass("animate").css("animation-delay", current2 + 's');
current2++;
});
}
});
});

You could use the Waypoint library to perform actions when the selected item is visible.
[Once you have downloaded the library][1]
[1]: https://github.com/imakewebthings/waypoints/zipball/latest and included the file "noframework.waypoints.min.js" in your html file:
<script src="/path/to/noframework.waypoints.min.js"></script>
You need to use this syntax to trigger the event.
var waypoint = new Waypoint({
element: document.getElementById('basic-waypoint'),
handler: function() {
notify('Basic waypoint triggered')
}
})
