Toggle active nav-link

I have a problem with toggling the active nav-link using JavaScript. I think my CSS is causing some problems but I do not know why.
I have the CSS code down at the bottom if that is any help. I have linked Jquery and my own name.js document correctly in my HTML head. I want to toggle the active link when it is visited.
var header = document.getElementById("nav-bar")
var toggled_nav = document.getElementsByClassName("nav-item")
for (var i = 0; i < toggled_nav.length; i++) {
toggled_nav[i].addEventListener("click", function() {
var current = document.getElementsByClassName("active");
current[0].className = current[0].className.replace(" active", "");
this.className += " active";
});
}

I simplified your code and created specific active classes for each nav. You can give the parent the click handler and refer to the children through e.target since in this case the children take up the full space of the parent.
var header = document.getElementById("nav-bar")
header.addEventListener("click",function(e){
has_class = header.querySelector(".active");
if(has_class)has_class.classList.remove("active");
e.target.classList.add("active");
});

For the first two .nav-item I see they are referring to different files. So in their curresponding files, you can mark them active.
For rest of the three .nav-item you can use (I am using JQuery since you mentioned it)
$('#nav-bar').on('click', '.nav-item', function(e) {
$('.nav-item.active', e.currentTarget).removeClass('active');
$(this).addClass('active');
}
make sure the css for the .active is being applied correctly.

You could do something like this; where you remove the active class for each item and then add it to the one that was clicked.
let items = document.querySelectorAll(".nav-item")
items.forEach(item => {
item.addEventListener("click", event => {
const current = document.querySelector('.active')
current.classList.remove('active')
item.classList.add("active")
})
})

How to make a toggle onclick to hide and show video player's UI?

I want to show and hide the video player's elements details, play_pause_button and controls_bar when the video player itself is clicked but not when its elements are clicked. I have made some progress but the video player's elements hide when I click on the elements which shouldn't happen. So how can I detect that the video player was clicked but not the video player's elements.
index.html:
var play_pause_button = document.getElementById("play_pause_button");
play_pause_button.style.visibility = "hidden";
var details = document.getElementById("details");
details.style.visibility = "hidden";
var controls_bar = document.getElementById("player_controller_bar");
controls_bar.style.visibility = "hidden";
document.getElementById("video_player_box").onclick = function () {
if (controls_bar.style.visibility == "hidden") {
play_pause_button.style.visibility = "visible";
details.style.visibility = "visible";
controls_bar.style.visibility = "visible";
} else {
play_pause_button.style.visibility = "hidden";
details.style.visibility = "hidden";
controls_bar.style.visibility = "hidden";
}
}

You can use the event's target property. The target property references the element that was actually clicked, even when you attach the handler on a ascending element
(see https://developer.mozilla.org/en-US/docs/Web/API/Event/target)
you will receive the reference to the event as the first argument of your onClick handler
myElement.onclick = function (ev) {
if (ev.target.id === 'details') {
// the clicked element is the details element
}
}
you can also check if the target is the video element for example.
console.log(ev.target.nodeName === 'VIDEO')

CSS, express and bootstrap : overflow and margin error

I stack two circles over an image, using the position and overflow properties.
It works fine but I have the circle running over the image on left and right (not top and left.
Here is the image : Circle overflowing
Here is the CSS.
.mainContainer {
background-color: #A6A4AA
}
.targetImage {
margin: 0;
width: 100%;
height: auto;
border: solid medium #2C3756;
border-radius: 0 0 8px 8px;
background-color: #A6A4AA;
position: relative;
}
#targetCol {
overflow: hidden;
position: absolute;
}
.impact, .ajustement {
position: absolute;
background-color: #dc022e;
border-radius: 100%;
opacity: 0.75;
margin: 0;
width: 100%;
height: auto;
border: solid medium #2C3756;
}
.ajustement {
opacity: 0.5;
}
The code source (ejs+bootstrap) : the row is a child of mainContainer
<div class="row"> <!-- Row : target -->
<div class= "col-xs-12" id="targetCol">
<img id="target" class="targetImage"></img>
<div id="ajustement" class="ajustement"></div>
<div id="impact" class="impact"></div>
</div>
</div>
How can I draw my circles into the images only, without running out the border ?
Here is what I would like :

Do you looking something like this:
body{
margin: 0;
background-color: #A6A4AA
}
.mainContainer {
background-color: #A6A4AA;
margin: 15px auto;

border-radius: 0 0 8px 8px;
background: #A6A4AA;
position: relative;
}
#targetCol {
overflow: hidden;
position: absolute;
border: 3px solid #2C3756;
line-height: 0;
border-radius: 12px;
}
.impact, .ajustement {

Toggle Class while removing class from siblings

I have a map where I am toggling a class when you click on a dot/location that pops up a tooltip. The issue I'm running into is that when I click on another dot the other siblings tooltips are not going away. I tried to solve this by removing the class of the siblings on click, but when I do this the toggle stops working and I cannot click the dot again to get rid of the active tooltip.
I need the toggle on the currently active tooltip to still work but I also need the sibling tooltips to disappear as well.
I hope I explained that right. Here is a codepen: http://codepen.io/anon/pen/BzQrLV
$('.dot').click(function() {
$('div.toggle-active').removeClass('toggle-active');
$(this).next().toggleClass('toggle-active');

Add .not($(this).next()) to your removeClass statement so you don't remove the active class from all the dots, just the dots not being clicked on.
$('.dot').click(function() {
$('div.toggle-active').not($(this).next()).removeClass('toggle-active');
$(this).next().toggleClass('toggle-active');
});

progress bar with reference line using css and html

I am trying to achieve a similar UI as shown in the image link: https://goo.gl/photos/4dNFyq8a3nESQj2g9 .
It is not a normal progress bar. I need to add a reference data line, the name for reference line (in the picture it is "TODAY") and the text inside the progress bar. Could anyone help me with this? I only can find a normal progress bar and I fails to add the reference data line & reference line text to it :(
I have my progress bar working, but I do not know how to add reference line and reference text.
