Many Thanks

You can try with javascript
<button id="mybutton" onclick="showButton()">Show Image </button>
function showButton(){
image = document.getElementById('nameOfImageHere');
image.style.display = "block";
}

Here we go:
1 Method:
You may use jQuery Hide(), Show() function :
<script>
$(document).ready(function(){
$("#buttonIdShow").click(function(){
$("#Image").hide();
});
$("#buttonIdHide").click(function(){
$("#Image").show();
});
});
</script>
<img id="Image"/> <!-Here is your image-->
<button type="button" id="buttonIdShow">Show</button> <!--Show button-->
<button type="button" id="buttonIdHide">Hide</button> <!--Hide button-->
2 Method: jQuery Animate CSS display:
<script>
$("#yourButton1Id").click(function(){
$("#ImageId").css("display","block");
});
$("#yourButton2Id").click(function(){
$("#ImageId").css("display","none");
});
</script>
Hope it helps;)

Toggle between different divs

I need a solution for toggle between divs. I have a sidebar with a group of buttons. When I enter the page with the sidebar I only want the div with the button group to appear, but when I press for example Info I want the info div to appear and the other divs to disappear, and when I press the back button on the Info div I again only want the button group to appear.
.info {
border-color: black;
background-color: #f1f1f1;
margin-left: 7%;
margin-right: 7%;
height: 60%;
position: relative;
}
.about {
display: none;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<button class="activeButton">Quotes</button>
<button class="activeButton">Additional</button>
<button class="activeButton">Additional</button>
</div>
<div class="info" id="info">

<button class="back-button">Back</button>

</div>
<script>
$(document).ready(function () {
$("#info-button").click(function () {
$("showall").hide();
$("#info").show();
});
});
</script>
</body>

You are missing the id identifier in your .click function. If you want the info div hidden on page load, make sure to set it to display none, then add another event handler for the #backBtn
$(document).ready(function () {
$("#info-button").click(function () {
$("#showall").hide();
$("#info").show();
});
$("#backBtn").click(function () {
$("#showall").show();
$("#info").hide();
});
});
.info {
display: none;
border-color: black;
background-color: #f1f1f1;
margin-left: 7%;
margin-right: 7%;
height: 60%;
position: relative;
}
.about {
display: none;
}

How To Create A Client-Sided Search Bar Using Javascript

I'm trying to create a client-sided search bar using javascript and I'm not sure how to do that and get it to function properly. I'm trying to create one without using PHP since I have no experience with server-sided programming. How would you create one that works with the client-side? Do you need an index for the search results and an API as well? And how would you use an index and an API? The goal of the search bar is to find terms or words that are present on the webpage is what I'm trying to achieve with it. It's to give the user a chance to search for the name of an article present in the webpage. Here is my current code if you want to see it: https://jsfiddle.net/snt87eg9/1/
<div class="topnav">
<a class="active" href="#home">Home</a>
News
Contact
About
<div class="search-container">
<form action="/action_page.php">
<input type="text" placeholder="Search.." name="search">
<button type="submit"><i class="fa fa-search"></i></button>
</form>
</div>
</div>
<div class="header">
<div id ="header">
<h2 style="text-indent: 1em; font-family: Helvetica; color: blue;">Articles</h2>
</div></div><br>
<div class="row">
<div class="leftcolumn">
<div class="card">
<div id="Title">
<h2>Article 1</h2>
<h5>Date</h5>
<p>Some text over there.,.. </p>
</div>
</div>
</div>
</div>
<div class="row">
<div class="card">
<div id="Title2">
<h2>Article 2</h2>
<h5>Date</h5>
<p> Some text over here..... </p>
</div>
</div>
</div>
```

You need a way to select the searchbar, articles and article titles,
lets say you give classes article and article-title and give the searchbar id="searchbar"
Document should look like this:
<div class="topnav">
<a class="active" href="#home">Home</a>
News
Contact
About
<div class="search-container">
<form action="/action_page.php">
<input type="text" placeholder="Search.." name="search" id="searchbar">
<button type="submit"><i class="fa fa-search"></i></button>
</form>
</div>
</div>
<div class="header">
<div id="header">
<h2 style="text-indent: 1em; font-family: Helvetica; color: blue;">Articles</h2>
</div>
</div><br>
<div class="row article">
<div class="leftcolumn">
<div class="card">
<div id="Title">
<a href="#">
<h2 class="article-title">Article 1</h2>
</a>
<h5>Date</h5>
<p>Some text over there.,.. </p>
</div>
</div>
</div>
</div>
<div class="row article">
<div class="card">
<div id="Title2">
<a href="#">
<h2 class="article-title">Article 2</h2>
</a>
<h5>Date</h5>
<p> Some text over here..... </p>
</div>
</div>
</div>
Here's the way to filter out what you wrote in the searchbar:
<script>
$('#searchbar').keyup(function(){
let articles = $('.article'); //get all elements with class="article"
let keyword = $(this).val().toLowerCase(); //get the content of the searchbar
if(keyword == "") //show all elements if searchbar is empty
articles.show();
else{ //else loop through articles and check if the keyword is in the title div
articles.each(function(element) {
let title = $(this).find('.article-title').text().toLowerCase();
(title.indexOf(keyword) >= 0) ? $(this).show() : $(this).hide();
});
}
});
</script>
The script uses jQuery , you can put this before the script if you don't have it already imported :
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

I just took the time to make a client-side search javascript function. But if you are not too familiar with javascript try to learn a little bit more before implementing this type of things.
$(document).ready(function() {
$("#header").hide().fadeIn(2000);
});
$(document).ready(function() {
$("#title").hide().fadeIn(2000);
});
$(document).ready(function() {
$("#footer").hide().fadeIn(2000);
});
function searchInArticles(word) {
const articles = document.querySelectorAll(".card");
articles.forEach(article => {
if (article.innerHTML.includes(word)) {
article.style.display = "block";
article.scrollIntoView();
} else {
article.style.display = "none";
}
})
}
searchInArticles("Yes");
//searchInArticles("Some");

How do I format chat app to show ellipses for the side bar, and keep each div highlighted after being clicked?

I'm building an HTML chat app template, and I ran into two major issues when trying to complete it.
The chat names on the side are not showing ellipses despite me using text-overflow: ellipse;
When anyone of the chats are clicked, I would like them to stay on an active color until I click on another one, but I'm not sure how to go about it.
Here's my HTML and CSS:
body{
background-image: url("../img/gradientBackgroundOne.png");
background-repeat: no-repeat;
background-attachment: fixed;
background-size: 100% 100%;
}
.wrapper{
display: grid;
grid-template-columns: 1fr 2fr;
width: 85vw;
height: 80vh;
margin: auto;
margin-top: 2%;
}
/*
* This section will style the sidebar, which will contain all of the users chats that they're in
*
*/
.sidebar{
display: grid;
grid-template-rows: 80px 60vh auto;
background-color: purple;
}
.sidebar > .chats-title{
background-color: violet;
}
.sidebar > .group-chats{
overflow-y: auto;
background-color: white;
}
.sidebar > .group-chats > .group-chat-name{
padding: 15px;
background-color: chocolate;
border: 1px solid black;
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
}
.sidebar > .group-chats > div:hover{
background-color:burlywood;
}

background-color:rgb(122, 184, 235);

What should I do? Thanks.

You probably have to use javascript to achieve this. The default functioning for the :active state is to snap back to the :hover state as soon as you click and release the mouse button.
.sidebar > .group-chats > div:active {
background-color: red;
}
If you remove the :hover state you'll make it stay red, but it's as far as I am concerned impossible to keep :active as long as :hover immediately takes over once the click is finished.

Edit: Forgot your ellipsis question. For this to work your element has to have a width. However, I am not able to solve it, your markup and css are confusing and adding width to what I think is the correct element doesn't work.
Edit 2: You could try a JS solution like this to make the active background color stick when you click the chat room divs. I have simplified. You can change this to use the container class that you already have and just add a unique class to all the divs inside of it that you want to make work with this JS:
const container = document.querySelector('.container')
const activeState = (e) => {
document.querySelectorAll('.active-color').forEach(link => link.classList.remove('clicked-color'))
if (e.target.className.toLowerCase() === 'active-color' )
e.target.classList.add('clicked-color')
}
container.addEventListener('click', (e) => {
activeState(e)
})
div.active-color {
padding: 2rem;
width: 300px;
background: #ddd;
margin: 1rem 0;
border-radius: 6px;
}
div.active-color:hover,
div.active-color:focus {
background: purple;
cursor: pointer;
}
div.active-color:active {
background: red;
}
div.active-color.clicked-color {
background: red;
}
<div class="container">
<div class="active-color">DIV 1</div>
<div class="active-color">DIV 2</div>
<div class="active-color">DIV 3</div>
<div class="active-color">DIV 4</div>

Ajax call not loading the pages on the main page

I try to load different pages using an ajax call. But the pages are not appearing on the main page.
This is the file:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>News Headlines</title>
<script src="Scripts/jquery.min.js"></script>
<link href="Content/site.css" rel="stylesheet">
<style>
#newslinks li {
display: inline-block;
margin-right: 20px;
}
#newslinks li a {
padding: 5px 10px;
background-color: white;
color: black !important;
text-decoration: none;
}
#newslinks li a:hover {
background-color: rgb(110,138,195);
color: white !important;
}
#headlines #newsItem {
margin-top: 10px;
padding: 20px;
border: 1px solid white;
}
</style>
<script>
$(document).ready(function() {
$('#newslinks a').click(function () {
var url = $(this).attr('href');
$('#healines').load(url + ' #newsItem');
//evt.pr.preventDefault();
return false;
});
}); // end ready
</script>
</head>
<body>
<div class="wrapper">
<header>
JAVASCRIPT <span class="amp">&</span> jQUERY: THE MISSING MANUAL
</header>
<div class="content">
<div class="main">
<h1>News Headlines</h1>
<ul id="newslinks">
<li>Today’s News</li>
<li>Yesterday’s News</li>
<li>Last Week’s News</li>
</ul>
<div id="headlines"></div>
</div>
</div>
<footer>
<p>JavaScript & jQuery: The Missing Manual, 3rd Edition, by David McFarland. Published by O'Reilly Media, Inc.</p>
</footer>
</div>
</body>
</html>
So you see three links. But if you click on one of the links nothing happens. I am using IIS. And yes it is enabled.
Thank you

Misspelled headlines in $('#healines').load(url + ' #newsItem');.

Why doesn't the menu background color change?

I have created 2 menus:prod & prod2, I find when the mouse focus on prod2, the background color is changed but when the mouse focus on prod1 the background color doesn't change.
Why it doesn't change?
Styles:
ul.hMenu {
margin: 0;
padding: 0;
z-index: 1;
}
ul.hMenu > li {
margin: 0;
padding: 0;
list-style: none;
float: left;
width:140px;
}
ul.hMenu li a {
display: block;
text-align: left;
text-decoration: none
}
ul.hMenu li > div {
position: absolute;
display: none;
}
ul.hMenu div a {background: yellow;
}
div.lay1{ float:left;}
div.lay1 br{line-height:50%}
.topMenu{font:bold 12px arial;color:#169e39;text-decoration: none;}
.secondMenu{font:12px arial;color:#000000;text-decoration: none;}
.arrow_box {
position: relative;
background: red;
border: 4px solid #c2e1f5;
}
.arrow_box:after, .arrow_box:before {
bottom: 100%;
border: solid transparent;
content: " ";
height: 0;
width: 0;
position: absolute;
pointer-events: none;
}
.arrow_box:after {
border-color: rgba(149, 213, 53, 0);
border-bottom-color: red;
border-width: 13px;
left: 10%;
margin-left: -13px;
}
.arrow_box:before {
border-color: rgba(194, 225, 245, 0);
border-bottom-color: #c2e1f5;
border-width: 19px;
left: 10%;
margin-left: -19px;
}
Script:
function showMenu(obj){
var a=obj.children[0];
a.style.color="blue";
var div = obj.children[1];
obj.style.backgroundColor="yellow";
div.style.display="block";
}
function hideMenu(obj){
var a=obj.children[0];
a.style.color="red";
var div = obj.children[1];
div.style.display="none";
obj.style.backgroundColor="";
}
HTML:
<ul class="hMenu">
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod</a>
<div><br/>
<!-- here-->
<div class="arrow_box" >
<div class="lay1">
<div>Manage Content<br> Message </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</div>
</li>
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod2</a>
<div class="arrow_box">
<div class="lay1">
<div>Manage Content<br> Message <br> Help </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</li>
</ul>
<br/><br/><br/><br/><br/>
Test
Problem In JsFiddle

I tested your code and it worked! what is your browser? please place a demo and also add this code as well
a.setAttribute('style','background-color:blue');
some browsers have incompatibility with element.style

give CSS Like this
.arrow_box{ position:absolute; white-space:nowrap}
Check this
http://jsfiddle.net/zz5XJ/2/

try the below HTML:
<body>
<ul class="hMenu">
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod</a>
<div class="arrow_box" >
<div class="lay1">
<div>Manage Content<br> Message </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</li>
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);">
<a style="color: red;" href="javascript:void(0);">prod2</a>
<div class="arrow_box">
<div class="lay1">
<div>Manage Content<br> Message <br> Help </div>
<br><br>
<div>Manage Assignment<br> User Inquiry</div>
</div>
</div>
</li>
</ul>
<br/><br/><br/><br/><br/>
Test
</body>

Please check your HTML :
Because you execute same function for both Pord or Pord2 but the Inner html is different for both li. so function showMenu() works different for both Pord or Pord2:
HTML:
<ul class="hMenu">
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);"><a style="color: red;"
href="javascript:void(0);">prod</a>
<div class="arrow_box">
<br />
<div class="lay1">
<div>
Manage Content<br>
Message
</div>
<br />
<br />
<div>
Manage Assignment<br>
User Inquiry</div>
</div>
</div>
</li>
<li onmouseover="showMenu(this);" onmouseout="hideMenu(this);"><a style="color: red;"
href="javascript:void(0);">prod2</a>
<div class="arrow_box">
<br />
<div class="lay1">
<div>
Manage Content<br>
Message
<br>
Help
</div>
<br />
<br />
<div>
Manage Assignment<br>
User Inquiry</div>
</div>
</div>
</li>
</ul>
Try This
UPDATED
Put <br /> before arrow_box div for both li and some change into Javascript:
var div = obj.children[2];
Javascript -
function showMenu(obj){
var a=obj.children[0];
a.style.color="blue";
var div = obj.children[2];
obj.style.backgroundColor="yellow";
div.style.display="block";
}
function hideMenu(obj){
var a=obj.children[0];
a.style.color="red";
var div = obj.children[2];
div.style.display="none";
obj.style.backgroundColor="";
}
