let NavBar = document.getElementById("xdd");
let bound = NavBar.getBoundingClientRect();
window.onscroll= function (){
console.log("scrolled")
console.log(bound)
if(bound.top >=0)
{
}

I am trying to detected whether an Elemnt is inside the Viewport. When i looked this up, i was directed to usimg getBoundingClientRect to get its location relative to the Viewport.
However, when i tried implementing this solution, it didnt work, as this always returned a DOMRect with the x,y, top and left values being 0 and the others staying constant no matter where i scroll.
The html element(s) i want to get the location of:
<header id="TNav">
<nav class="TopNavigation" id="xdd">
<button class="TopNavBtn">xd</button>
</nav>
</header>
Its CSS:
header{
height: 5vh;
grid-column: 1/3;
grid-row:1/2 ;
background-color: black;
z-index: 2;
display: block;
}
.TopNavigation{
display: flex;
flex-direction: column;
}
The JS code:
let NavBar = document.getElementById("xdd");
let bound = NavBar.getBoundingClientRect();
window.onscroll= function (){
console.log("scrolled")
console.log(bound)
if(bound.top >=0)
{
}
else
{
console.log("isnt")
}
}
// to check if the DOM is loaded
document.addEventListener("DOMContentLoaded", (event) =>{
console.log("ready");
})
the code is implemented at the very bottom of the <body>.
I tried testing if the DOM is loaded and changing which element i read the location of.
Here is what the the getBoundingClientRect() returns:


Thanks to user Unmitigated, i now have the answer:
The let bound = NavBar.getBoundingClientRect had to be moved inside the window.onscroll event handler, like so:
<script>
let NavBar = document.getElementById("xdd");
window.onscroll= function (){
let bound = NavBar.getBoundingClientRect();
console.log("scrolled")
console.log(bound)
if(bound.top >=0)
{
}
else
{
console.log("isnt")
}
}
// to check if the DOM is loaded
document.addEventListener("DOMContentLoaded", (event) =>{
console.log("ready");
})
</script>

You need to close the menu on link click as well as cancel. I've created a function for that to avoid duplication.
const body = document.querySelector("body");
const navbar = document.querySelector(".navbar");
const menuBtn = document.querySelector(".menu-btn");
const cancelBtn = document.querySelector(".cancel-btn");
const menuLinks = document.querySelectorAll('.menu-list li a');
const closeMenu = () => {
body.classList.remove("disabled");
navbar.classList.remove("show");
menuBtn.classList.remove("hide");
};
menuBtn.onclick = () => {
navbar.classList.add("show");
menuBtn.classList.add("hide");
body.classList.add("disabled");
};
cancelBtn.onclick = () => {
closeMenu();
};
menuLinks.forEach(link => {
link.onclick = () => {
closeMenu();
};
});
window.onscroll = () => {
this.scrollY > 20 ? navbar.classList.add("sticky") : navbar.classList.remove("sticky");
};

Navbar won't hide on scroll

I've just included a button on the bottom right of the site to allow users to go back to the top of the page but it seems to have cancelled out my navbar from hiding when the user scrolls. I've been looking at it all morning and would really appreciate a fresh pair of eyes to look at it, any help would be great!
Thanks.

window.onscroll can be set in one exemplary only, when you set it a second time, it replaces the first.
Solution: put all your code in the same function (I added scrollFunction(); to the first, but that can be the contrary):
var prevScrollpos = window.pageYOffset;
window.onscroll = function() {
var currentScrollPos = window.pageYOffset;
if (prevScrollpos > currentScrollPos) {
document.getElementById("navigation").style.top = "0";
} else {
document.getElementById("navigation").style.top = "-70px";
}
prevScrollpos = currentScrollPos;
scrollFunction();
}
function scrollFunction() {
if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
document.getElementById("myBtn").style.display = "block";
} else {
document.getElementById("myBtn").style.display = "none";
}
}
function topFunction() {
document.body.scrollTop = 0;
document.documentElement.scrollTop = 0;
}

The issue here is that the second onscroll overrides the first one.
So, you can move the code to single function. I have updated the code below:
var prevScrollpos = window.pageYOffset;
window.onscroll = function() {scrollFunction()};
function scrollFunction() {
if (document.body.scrollTop > 20 || document.documentElement.scrollTop > 20) {
document.getElementById("myBtn").style.display = "block";
} else {
document.getElementById("myBtn").style.display = "none";
}
var currentScrollPos = window.pageYOffset;
if (prevScrollpos > currentScrollPos) {
document.getElementById("navigation").style.top = "0";
} else {
document.getElementById("navigation").style.top = "-70px";
}
prevScrollpos = currentScrollPos;
}
function topFunction() {
document.body.scrollTop = 0;
document.documentElement.scrollTop = 0;
}

Give opacity 0.5 to the 30% of scrollable div

I have a scrollable div for messages. I want opacity of 0.5 to the content at top 30% of scrollable div Like in image.
.
So while scrolling, whichever message comes on that div should have opacity 0.5. I have tried using an extra div background with linear gradient but the background color is clearly visible from my page's background color.Like this image So I just want to change the opacity of content but not the background of that region.
Thanks in advance.

html link and slider conflict

I use a scroll slider with the mouse or by clicking on image. My problem is that the other links as in the footer or another no longer work. I added "onclick =" window.open (this.href); return false; "but now it's the slide that no longer works when the footer link was clicked.
Appreciate the help
$(function() {
//make functions first
function showSlide(n) {
// unbind event listener to prevent retriggering
$("body").unbind("mousewheel");
currSlide += n;
// make sure currslide does not go out of min or max boundaries
currSlide = currSlide <= 0 ? 0 : currSlide >= $slide.length-1 ? $slide.length-1 : currSlide;
// displacement is window width times current slide number
var displacment = window.innerWidth*currSlide;
// translate slides div across to appropriate slide
$('.slides').css('transform', 'translateX(-'+displacment+'px)');
// give small delay before rebinding event to prevent retriggering
setTimeout(function() {
$("body").bind('mousewheel', mouseEvent);
}, 800);
// change active class on link
$('nav a.active').removeClass('active');
$($('a')[currSlide]).addClass('active');
}
function mouseEvent(e, delta) {
// On upwards scroll, show next slide (+1)
// otherwise on downwards scroll show prev slide (-1)
showSlide(delta >= 0 ? -1 : 1);
e.preventDefault();
}
$('nav a').click(function(e) {
// When link clicked, find slide it points to
var newslide = parseInt($(this).attr('href')[1]);
// find how far it is from current slide
var diff = newslide - currSlide - 1;
showSlide(diff); // show that slide
e.preventDefault();
});
$(window).resize(function(){
// Keep current slide to left of window on resize
var displacment = window.innerWidth*currSlide;
$('.slides').css('transform', 'translateX(-'+displacment+'px)');
});
//declare vars then make things happen
var currSlide = 0; //Keeps track of slide
var $slide = $('.slide'); //all slides
// give active class to first link
$($('nav a')[0]).addClass('active');
//add event listener for mousescroll

Add onkeypress="window.open(this.href); return false;" to your code
pixabay.com
Remove below code
$('nav a').click(function(e) {
// When link clicked, find slide it points to
var newslide = parseInt($(this).attr('href')[1]);
// find how far it is from current slide
var diff = newslide - currSlide - 1;
showSlide(diff); // show that slide
e.preventDefault();
});

add this code to your js file.

e.preventDefault();
});

// displacement is window width times current slide number
var displacment = window.innerWidth*currSlide;
// translate slides div across to appropriate slide
$('.slides').css('transform', 'translateX(-'+displacment+'px)');
// give small delay before rebinding event to prevent retriggering

I have made the changes in jquery .You can take below code.
$(function() {
//make functions first
function showSlide(n) {
// unbind event listener to prevent retriggering
$("body").unbind("mousewheel");
currSlide += n;
// make sure currslide does not go out of min or max boundaries
currSlide = currSlide <= 0 ? 0 : currSlide >= $slide.length-1 ? $slide.length-1 : currSlide;
// displacement is window width times current slide number
var displacment = window.innerWidth*currSlide;
// translate slides div across to appropriate slide
$('.slides').css('transform', 'translateX(-'+displacment+'px)');
// give small delay before rebinding event to prevent retriggering
setTimeout(function() {
$("body").bind('mousewheel', mouseEvent);
}, 800);
// change active class on link
$('nav #nav-thumbnails a.active').removeClass('active');
$($('a')[currSlide]).addClass('active');
}
function mouseEvent(e, delta) {
// On upwards scroll, show next slide (+1)
// otherwise on downwards scroll show prev slide (-1)
showSlide(delta >= 0 ? -1 : 1);
e.preventDefault();
}
$('nav #nav-thumbnails a').click(function(e) {
// When link clicked, find slide it points to
var newslide = parseInt($(this).attr('href')[1]);
// find how far it is from current slide
var diff = newslide - currSlide - 1;
showSlide(diff); // show that slide
e.preventDefault();
});
$(window).resize(function(){
// Keep current slide to left of window on resize
var displacment = window.innerWidth*currSlide;
$('.slides').css('transform', 'translateX(-'+displacment+'px)');
});
//declare vars then make things happen
var currSlide = 0; //Keeps track of slide
var $slide = $('.slide'); //all slides
// give active class to first link
$($('nav #nav-thumbnails a')[0]).addClass('active');
//add event listener for mousescroll
$("body").bind('mousewheel', mouseEvent);
})

vertical tabs same height as content

Practically I have a vertical tabs menu and what I am trying to achieve is to have the menu wrapper height dynamically set depending on the content or the tabs height (the one that is bigger wins)
Here is a jsfiddle of what I have made so far : http://jsfiddle.net/f9zt9xqr/2/
HTML:
<div id="page-wrap">
<div class="tabs">
<div class="tab">
<input type="radio" id="tab-1" name="tab-group-1" checked>
<label for="tab-1">Tab One</label>
<div class="content">
<p>Stuff for Tab One</p>
</div>
</div>
<div class="tab">
<input type="radio" id="tab-2" name="tab-group-1">
<label for="tab-2">Tab Two</label>
<div class="content">

</div>
</div>
<div class="tab">
<input type="radio" id="tab-3" name="tab-group-1">
<label for="tab-3">Tab Three</label>
<div class="content">
<p>Stuff for Tab Three</p>
</div>
</div>
</div>
</div>
CSS:
* {
gmargin: 0;
spadding: 0;
}
body {
background: #f9f9fc;
}
#tab-1{
position: absolute;
top: -200px;
left: -200px;
}
#tab-3{
position: absolute;
top: -200px;
left: -200px;
}
#tab-2{
position: absolute;
top: -200px;
left: -200px;
}
#page-wrap{
position: relative;
background:#123456;
}
.tabs {
position: relative;
hmin-height: 200px;
/* This part sucks */
clear: both;
smargin: 25px 0;
}
.tab {
rfloat: left;
sposition:absolute;
height: auto;
}
.tab label {
background: #f5f5f9;
padding: 10px;
border: 1px solid #ccc;
margin-left: -1px;
dposition: relative;
left: 1px;
width: 70px;
display: block;
}
.tab[type=radio] {
display: none;
}
.content {
display:none;
position: absolute;
top: 0px;
left: 92px;
background: white;
right: 0;
zbottom: 0;
padding: 20px;
border: 1px solid #ccc;
}
[type=radio]:checked ~ label {
background: white;
sborder-bottom: 1px solid white;
z-index: 2;
}
[type=radio]:checked ~ label ~ .content {
8overflow:auto;
display:inline;
z-index: 1;
}
on the second option you can clearly notice that the page-wrap doesn't extend to the content size
I was thinking that this is because content is an inner element of tab and therefore should be modified there but it didn't work either.
Any suggestions how to achieve that and maybe don't mind explaining what I was doing wrong ?

.tabs { display:table; }
label {display:table-cell;}
.content {display-table:cell;}
remove position absolute as it won't help you in this situation. See how it goes
PS: remove the display:inline from [type="radio"]:checked ~ label ~ .content

I updated the css to take out some of the absolute positioning and made the content have a min-height of 100%, this also required taking out the vertical padding of the content area.
http://jsfiddle.net/f9zt9xqr/4/
.content {
display:none;
position: absolute;
top: 0;
left: 92px;
background: white;
right: 0;
padding: 0 20px;
border: 1px solid #ccc;
min-height: 100%;
}
