Navigation bar - not closing when clicking the current section

Hello,
I have a working navigation bar sliding out of the page when the user clicks on the menu icon. It shows up only on mobile version of the website.
When u want to close the bar, you click on "x" or outside the div, somewhere in the background.
When I click on a section name, the page refreshes and the navigation closes. The problem appears when I click on the current section. The page does not refresh, so you have to close the navigation manually.
I want my navigation bar to close everytime an user clicks a link. Do you have any idea how can I achieve that?
This is my website: https://www.poznanprzeprowadzki.pl

<div id="menu-mobile-background" class="menu-mobile-background" onclick=closeNav()>
</div>
This is my css for this part:
.menu-mobile {
display: block;
height: 100%;
width: 250px;
position: fixed;
z-index: 9999;
top: 0;
right: -255px;
background-color: rgba(100,100,100,1);
overflow-x: hidden;
transition: 0.4s;
}
.menu-mobile-close {
position: absolute;
top: 5px;
right: 10px;
transition: 0.05s;
}
.menu-mobile-background {
right: 0;
top: 0;
position: fixed;
overflow: hidden;
z-index: 9998;
width: 0px;
height: 100%;
background-color: rgba(0,0,0,0.3);
}
.menu-mobile-header {
min-width: 250px;
padding: 16px;
text-align: center;
background-color: white;
}
.menu-mobile-header p {
font-family: Open Sans;
font-size: 14px;
color: rgba(100,100,100,1);
padding: 2px;
font-weight: 500;
display: block;
white-space: nowrap;
}
.menu-mobile-header img {
margin: 0 auto;
height: 65px;
padding-bottom: 6px;
}
.menu-mobile-close p:hover {
color: rgba(240,240,240,1);
cursor: pointer;
}
.menu-mobile-close p {
font-family: Open Sans;
font-size: 18px;
color: rgba(100,100,100,1);
font-weight: 600;
display: block;
}
This is my JS for this part:
function openNav() {
document.getElementById("menu-mobile").style.right = "0px";
document.getElementById("menu-mobile-background").style.width = "100%";
}
function closeNav() {
document.getElementById("menu-mobile").style.right = "-255px";
document.getElementById("menu-mobile-background").style.width = "0px";
}
Here is a picture of my navigation bar:

Add this script in your js file:
$(document).ready(function() {
$('.menu-mobile a').click(function(e) {
e.preventDefault(); // if the link don't reload all the page
closeNav();
})
});
Another solution, if you want to wait something before redirect:
$(document).ready(function() {
$('.menu-mobile a').click(function(e) {
e.preventDefault(); // is required
closeNav();
setTimeout(() => {
const nextPage = e.currentTarget.href;
window.location.href = nextPage;
},1000) // set the time here in milliseconds
})
});

Navigation Bar retains class when scrolling despite having a function to remove the class

I'm currently trying to create a navigation bar that sticks when you scroll past. I've gotten to the point where the bar will stick when I scroll past, but when I scroll back to the top the navbar is still sticking. I've been able to troubleshoot to realize that the navbar.offsetTop is being set to 0 when scrolling past, which causes the class "sticky" to never be removed. How can I fix this so that the navbar retains its original offset while being "stuck" to the top of the page?

}
.navbar {
list-style-type: none;

}
.navbutton {

.navbutton:hover {

}
.sticky {

top:0;
width: 100%;
}
.content {
padding: 16px;
}
.sticky + .content {
padding-top: 60px;
}
Javascript
function stickyNav() {
var navbar = document.getElementById("navbar");
var navTop = navbar.offsetTop;
console.log('navTop = ' + navTop);
console.log('scrollY = ' + window.scrollY);
if (window.scrollY >= navTop) {
navbar.classList.add("sticky");
}
else {
navbar.classList.remove("sticky");
}
}
window.addEventListener('scroll', stickyNav);

The problem is in the function definition of stickyNav.
What I'm seeing is stickyNav function is registered as a callback for the scroll event. But the variables navbar and navTop are inside the function which is assigning values to them every time you scroll. And navTop is getting assigned 0 every time. And the sticky class is never removed.
Try avoiding reassigning values. This worked for me.

How to make images change a little quicker?

My code works just fine but for some reason when you click on the play button it takes a bit longer to switch over to the pause sign, and occasionally it takes a bit longer for the pause button to go to the play button. I also have one more question, when you click on the rain and beach icon there's a blue square border that I didn't remember putting, how do you remove it?
Thanks, Love2code

Because your SVGs are remotely sourced, it takes a bit of time to download them. I've created two hidden images with the remote sources. This will download these and have them ready in your cash for when you need them. I've also changed the sequence of when you switch the source path to come before you play the video.
I've set all elements to have an outline of none to take away the blue border when clicking on the image.
const app = () => {
const song = document.querySelector(".song");
const play = document.querySelector(".play-container");
const outline = document.querySelector(".moving-outline circle");
const video = document.querySelector(".vid-container video");
//Sounds
const sounds = document.querySelectorAll(".sound-picker button");
//Time Display
const timeDisplay = document.querySelector(".time-display");
//Get length of the outside
const outlineLength = outline.getTotalLength();
//Duration
let fakeDuration = 600;
outline.style.strokeDasharray = outlineLength;
outline.style.strokeDashoffset = outlineLength;
//play sounds
play.addEventListener("click", () => {
checkPlaying(song);
});
//stop and play the sounds
const checkPlaying = song => {
if (song.paused) {
play.src = 'https://www.dropbox.com/s/3zvnjkebwt1sjgq/download%20%283%29.svg?raw=1';
song.play();
video.play();
} else {
play.src = 'https://www.dropbox.com/s/8unx3knosmefedk/download%20%281%29.svg?raw=1';
song.pause();
video.pause();

Creating an onclick event for a button with a dropdown menu

I've been learning HTML and CSS for some weeks now and I start feeling comfortable with those. However I'm trying to learn JavaScript too.
I've been working on a button in HTML and CSS, you can view the demo of the button here.
I want to make the dropdown menu visible when you click the button and also if you click the button again the dropdown menu disappears.
Is there any simple or understandable way for creating a function which does this in JavaScript?
Here is the code I have:
HTML:
<div id="language-wrapper">
<a class="language-icon fr" href="#" alt="choose-your-language">Language</a>
<div id="language-dropdown">
<h3>Choose your language</h3>
<a class="language-links" href="#">Chinese</a>
<a class="language-links" href="#">Danish</a>
<a class="language-links" href="#">Deutsch</a>
<a class="language-links" href="#">English</a>
<a class="language-links" href="#">Espanol</a>
<a class="language-links" href="#">Filipino</a>
<a class="language-links" href="#">Hindu</a>
<a class="language-links" href="#">Italiano</a>
<a class="language-links" href="#">Norsk</a>
<a class="language-links" href="#">Nederlands</a>
<a class="language-links" href="#">Polski</a>
<a class="language-links" href="#">Portugues</a>
<a class="language-links" href="#">Svenska</a>
<a class="language-links" href="#">Suomi</a>
<a class="language-links" href="#">Turkce</a>
<a class="language-links" href="#">Urdu</a>
<p>Do you speak multiple languages or can't find your language? <font color="#d13030">Help us translate!</font><p>
</div> <!-- end of language-dropdown class -->
</div> <!-- end of language-wrapper -->
CSS:
#language-wrapper { display: inline-block; }
#language-wrapper:hover #language-dropdown { opacity: 1; display: block; }
.language-icon {
color: #fff;
font-weight:700;
padding-right:20px;
padding-left:30px;
display:inline-block;
font-size:11px;
text-align:right;
text-decoration:none;
position:relative;
left: 0; top: 0;
}
.fr { background: url("images/language-sprite.png") no-repeat 0 0; }
.fr:hover { background: url("images/language-sprite.png") no-repeat 0 -20px; color: #d13030; }
.language-icon:before {
content:'\25BE';
width:0px;
height:0;
position:absolute;
right:16px;
top: 0;
}
.language-icon:hover:before {
color: #d13030;
content: '\25B4';
top: -1px;
}
/* ------------------ LANGUAGE DROPDOWN ------------------ */
#language-dropdown {
opacity: 0;
width: 1023px;
display: none;
margin-top: 3px;
left: 0;
position: absolute;
border: 1px solid #ddd;
background: #fff;
box-shadow: 0px 3px 3px #b3b3b3;
}
#language-dropdown h3 {
color: #d13030;
font-size: 14px;
font-weight: normal;
padding: 5px 15px 0px 15px;
}
#language-dropdown p {
font-size: 12px;
padding: 0px 0px 10px 15px;
}
#language-dropdown a {
padding: 0px 0px 0px 15px;
}
.language-links {
font-size: 12px;
text-decoration: none;
color: #2793e6;
}
.language-links:hover {
text-decoration: underline;
}

it can be a basic toggle display function on onclik event:
function toggle(el) {
var tag=document.getElementById(el);
tag.style.display = tag.style.display === 'block' ? 'none' : 'block';
// set as defaut oposite defaut active value in document
// here defaut is set to block cause it is none in CSS
}
<a class="language-icon fr" href="#" alt="choose-your-language" onclick="toggle('language-dropdown');">Language</a>
test here : http://codepen.io/anon/pen/cHIrd/
note:
opacity:0; removed from your initial CSS
Better practice is to toggle class not style values :)
and maybe to set onclick event via javScript.
return false can be added to avoid link to href .
<a class="language-icon fr" href="#" alt="choose-your-language" onclick="toggle('language-dropdown');return false;">Language</a>

The Html
<button id="clickme">Clickme</button>
<h1 id="Another">Menu</h1>
The JavaScript:
document.getElementById("clickme").onclick=function(){
var el = document.getElementById('Another');
if (el.style.display == '') {
el.style.display = 'none';
alert("hide");
}else{
el.style.display = '';
alert("show");
}
};
Here is a sample

Drag And Drop panels in a web page using JavaScript, CSS, HTML

I want to drag 2 panels in a page. I am able to drag 2 panels "FirstName" and "SecondName". but my requirement is I need to drag one panel above another. When I drag one panel to other end the panel I dragged back ground must be in white. I figured out something by looking at some tutorials, but I couldn't find the solution. Please help me if anyone knows the solution.
My JavaScript code is
Element.prototype.addClassName = function(name) {
if (!this.hasClassName(name)) {
this.className = this.className ? [this.className, name].join(' ') : name;
}
};
Element.prototype.removeClassName = function(name) {
if (this.hasClassName(name)) {
var c = this.className;
this.className = c.replace(new RegExp("(?:^|\\s+)" + name + "(?:\\s+|$)", "g"), "");
}
};
var samples = samples || {};
// Almost final example
(function() {
var id_ = 'columns-almostFinal';
var cols_ = document.querySelectorAll('#' + id_ + ' .column');
var dragSrcEl_ = null;
this.handleDragStart = function(e) {
e.dataTransfer.effectAllowed = 'move';
e.dataTransfer.setData('text/html', this.innerHTML);
dragSrcEl_ = this;
this.style.opacity = '0.8';
// this/e.target is the source node.
this.addClassName('moving');
};
this.handleDragOver = function(e) {
if (e.preventDefault) {
e.preventDefault(); // Allows us to drop.
}
e.dataTransfer.dropEffect = 'move';
return false;
};
this.handleDragEnter = function(e) {
this.addClassName('over');
};
this.handleDragLeave = function(e) {
// this/e.target is previous target element.
this.removeClassName('over');
};
this.handleDrop = function(e) {
// this/e.target is current target element.
if (e.stopPropagation) {
e.stopPropagation(); // stops the browser from redirecting.
}
// Don't do anything if we're dropping on the same column we're dragging.
if (dragSrcEl_ != this) {
dragSrcEl_.innerHTML = this.innerHTML;
this.innerHTML = e.dataTransfer.getData('text/html');
}
return false;
};
this.handleDragEnd = function(e) {
// this/e.target is the source node.
this.style.opacity = '1';
[].forEach.call(cols_, function (col) {
col.removeClassName('over');
col.removeClassName('moving');
});
};
[].forEach.call(cols_, function (col) {
col.setAttribute('draggable', 'true'); // Enable columns to be draggable.
col.addEventListener('dragstart', this.handleDragStart, false);
col.addEventListener('dragenter', this.handleDragEnter, false);
col.addEventListener('dragover', this.handleDragOver, false);
col.addEventListener('dragleave', this.handleDragLeave, false);
col.addEventListener('drop', this.handleDrop, false);
col.addEventListener('dragend', this.handleDragEnd, false);
});
})();

Please take a look here. You can see different demos. You will have to mix and match, but basically using jquery droppable you can set docking areas for draggable items and set them to snap to location. JavaScript & jQuery; how to do snapping drag and drop

jQuery is redundant code for that. I don't want additional frameworks too . All can be done with Html/css/javaScript without jQuery. Cheers Swaroop !
