I'm an absolute beginner in javascript I want to open and close the burger menu. I don't know why it doesn't work with me. When I write .open{display:block} it shows up and I can't even open or close the burger menu how I can fix this and why it shows up like this ?
here the code:
let btn = document.getElementById('btn-js');
let sidebar = document.getElementById('side-bar');
btn.addEventListener('click',show());
function show(){
sidebar.classList.toggle('open');
}
*{
margin: 0;
padding:0;
box-sizing: border-box;
list-style: none;
}
.side-bar{
display: none;
background: cornflowerblue;
width: 275px;
text-align: center;
font-size: 19px;
}
.side-links{
padding: 30px 0;
}
.side-links li{
padding: 30px 0;
}
#media all and (max-width:800px) {
.open{
display: block;
}
}

I am new at web development and facing some problem in creating a web page. Actually, I was creating a loading bar animation at the top of the window and set its width to 100vw but it is taking more space than it should take. Here's a picture to demonstrate:
As you can see in the top-right corner it is overflowing the window. Why is that so?
Here's my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Loading Bar</title>
<style>
#progress{
background-color: red;
height: 3px;
width: 0vw;
transition: width 3s ease-in-out;
}
*{
margin: 0;
padding: 0;
}
header {
height: 122px;
background-color: black;
}
main {
height: 899px;
background-color: blue;
}
</style>
</head>
<body>
<div id="progress"></div>
<header></header>
<main>
<button id="btn">Reload</button>
</main>
</body>
<script>
btn.addEventListener("click", ()=>{
progress.style.width = "100vw"
})
</script>
</html>
Thanks in advance!!
Try adding max-width: 100% to your progress bar css, according to https://caniuse.com/viewport-units
there is a known issue on firefox in which the 100vw considers the entire length of the page including the vertical scrollbar as its width. This vertical scrolls is what making your webpage have an horizontal overflow.

Attempting a vanilla js solution to focus .btn-1 by default on page load.
Can't figure out why I keep getting this error : index.js:2 Uncaught TypeError: document.getElementsByClassName(...).focus is not a function at window.onload (index.js:2)
Anyone have thoughts on this please?
index.html :

<button class="btn btn-2">2</button>
<button class="btn btn-3">3</button>
<script src="index.js" async defer></script>
</body>
</html>
index.css :
.btn {
/* background-color: #4caf50; Green */
border: none;
color: white;
padding: 15px 32px;
text-align: center;
text-decoration: none;
display: block;
font-size: 16px;
margin: 1em;
}
.btn:hover {
background-color: grey;
}
.btn:focus {
background-color: blue;
}
index.js :
window.onload = function () {
document.getElementsByClassName('btn-1').focus();
};
The getElementsByClassName returns an array you can do this if you do like this
window.onload = function () {
document.getElementsByClassName('btn-1')[0].focus();
};
or you can use querySelector instead which targets the first element on the document
window.onload = function () {
document.querySelector('.btn-1').focus();
};
Have you tried the autofocus attribute you can give to the button elements.

<button type="button" autofocus>Click Me!</button>

You need a clearfix for the container of your floated items.
.OEContainer {
background-color: beige;
min-height: 10em;
vertical-align: middle;
padding: 10px;
max-width:1130px;
margin:auto;
text-align:center;
justify-content:space-between;
}
.OEItems {
min-height: 10em;
vertical-align: middle;
padding: 0px;
max-width:1130px;
margin:auto;
text-align:center;
justify-content:space-between;
}
.clearfix::after { /* clearfix class to expand the element back to its normal height */
content: '';
display: block;
clear: both;
}
.OECell {
background-color: lightblue;
min-height: 10em;
vertical-align: middle;
padding: 0px;
width:250px;
text-align:center;
float: left;
margin: 5px;
}
#media (max-width: 500px) {
.OEContainer {
flex-direction: column;
align-items: center;
}
}

When you use floats for all of the children of an element - it will collapse 0 height ( minus padding and margins etc ) unless you force it to expand to the size of it's children with a clearfix. Essentially it's a bug/quirk in browsers that's been persistent for a while.
Although this answers your questions I would advise against using floats wherever possible and use flexbox instead. Overall a lot less messy than floats in my opinion.

Scroll to the top of the page using JavaScript?
(49 answers)
Closed 2 years ago.
So I have the following in my HTML page:
and i intentionally made it so that the "overflow" happens which results in the scrollbar at the right.
So i made a button called "Click to scroll up". So what i wanted was that everytime we click that button, the document would immediately scroll all the way up. Which means if I were to navigate all the way down, and click the button, it would bring me all the way up.
I looked up and there's a method "scrollTop" but it doesn't seemed to work. Would appreciate some help on this.
document.getElementById("scrollup").addEventListener("click", scrollUpmost);
function scrollUpmost() {
$(document).scrollTop();
}

margin: 0;
