We Keep Coding

I'm trying to do a Todo List App and when i pressed the add task its not adding below

I created a createElement for the todo List and the appendchild but it's not adding to my website this is the code below
window.addEventListener('DOMContentLoaded', () => {
const form = document.querySelector("#add-todo-form");
const input = document.querySelector("#new-todo-input");
const listTask = document.querySelector('#todo-list');
form.addEventListener('submit', (e) => {
e.preventDefault();
const task = input.value;
const todoList = document.createElement('div');
todoList.classList.add('todo-item');
const label = document.createElement('label');
const input = document.createElement('input');
const span = document.createElement('span');
label.appendChild(input);
label.appendChild(span);
const todoContent = document.createElement('div');
todoContent.classList.add('todo-content');
todoList.appendChild(todoContent);
const todoInput = document.createElement('input');
todoInput.classList.add('text');
todoInput.type = 'text'
todoInput.value = task;
todoInput.setAttribute('readonly', 'readonly');
todoContent.appendChild(todoInput);
const todoAction = document.createElement('div');
todoAction.classList.add('action');
const todoEdit = document.createElement('i');
todoEdit.classList.add('bi-pencil-square');
const todoDelete = document.createElement('i');
todoDelete.classList.add('bi-trash3-fill');
todoAction.appendChild(todoEdit);
todoAction.appendChild(todoDelete);
todoList.appendChild(todoAction);
listTask.appendChild(todoList);
input.value = '';
todoEdit.addEventListener('click', (e) => {
if (todoEdit.innerText.toLowerCase() == 'bi-pencil-square') {
todoInput.removeAttribute("readonly");
todoInput.focus();
} else {
todoEdit.innerText = "bi-pencil-square";
todoInput.setAttribute("readonly", "readonly");
}
});
todoDelete.addEventListener('click', (e) => {
listTask.removeChild(todoList)
});
});
});

I've tried using the appendchild for a simple button and then a word will appear but when I applied the code to the todo list the task I input its not adding the list and I'm achieving this type of todo list in the youtube: https://www.youtube.com/watch?v=MkESyVB4oUw&t=6s

just change your form event listener two lines as i marked
// changed below two lines
const textbox = document.querySelector("#new-todo-input");
const task = textbox.value;
window.addEventListener('DOMContentLoaded', () => {
const form = document.querySelector("#add-todo-form");
const input = document.querySelector("#new-todo-input");
const listTask = document.querySelector('#todo-list');
form.addEventListener('submit', (e) => {
e.preventDefault();
// changed below two lines
const textbox = document.querySelector("#new-todo-input");
const task = textbox.value;
const todoList = document.createElement('div');
todoList.classList.add('todo-item');
const label = document.createElement('label');
const input = document.createElement('input');
const span = document.createElement('span');
label.appendChild(input);
label.appendChild(span);
const todoContent = document.createElement('div');
todoContent.classList.add('todo-content');
todoList.appendChild(todoContent);
const todoInput = document.createElement('input');
todoInput.classList.add('text');
todoInput.type = 'text'
todoInput.value = task;
todoInput.setAttribute('readonly', 'readonly');
todoContent.appendChild(todoInput);
const todoAction = document.createElement('div');
todoAction.classList.add('action');
const todoEdit = document.createElement('i');
todoEdit.classList.add('bi-pencil-square');
const todoDelete = document.createElement('i');
todoDelete.classList.add('bi-trash3-fill');
todoAction.appendChild(todoEdit);
todoAction.appendChild(todoDelete);
todoList.appendChild(todoAction);
listTask.appendChild(todoList);
input.value = '';
todoEdit.addEventListener('click', (e) => {
if (todoEdit.innerText.toLowerCase() == 'bi-pencil-square') {
todoInput.removeAttribute("readonly");
todoInput.focus();
} else {
todoEdit.innerText = "bi-pencil-square";
todoInput.setAttribute("readonly", "readonly");
}
});
todoDelete.addEventListener('click', (e) => {
listTask.removeChild(todoList)
});
});
});

I want to style the button with a straight cut bottom right corner but I got the problem. the problem is when I use clip-path in css the after pseudo-elements disappear
My button:
What I want:
I used clip-path but the after pseudo-elements disappear
#import url('https://fonts.googleapis.com/css2?family=Noto+Sans+Lao:wght#500;700&display=swap');
body {
height: 100vh;
background-color: rgba(8, 41, 85, 1);
display: flex;
align-items: center;
justify-content: center;
}
.button-52 {
clip-path: polygon(100% 0, 100% 69%, 92% 100%, 0 99%, 0 0);
font-family: "Noto Sans Lao";
padding: .5rem 2rem;
font-weight: bold;
font-size: 16px;
font-weight: 200;
letter-spacing: 1px;
outline: 0;
border: none;
cursor: pointer;
position: relative;
background-color: #fff;
user-select: none;
-webkit-user-select: none;
touch-action: manipulation;
transition: ease-in .2s;
}
.button-52:after {

<button class="button-52" role="button">ຂໍ້ມູນເພີ່ມເຕີມ</button>

You can "extend" clip-path to include the ::after element:
#import url('https://fonts.googleapis.com/css2?family=Noto+Sans+Lao:wght#500;700&display=swap');
body {
height: 100vh;
background-color: rgba(8, 41, 85, 1);
display: flex;
align-items: center;
justify-content: center;
}
.button-52 {
clip-path: polygon(100% -20%, 100% 69%, 92% 100%, -20% 99%, -20% -20%);
font-family: "Noto Sans Lao";
padding: .5rem 2rem;
font-weight: bold;
font-size: 16px;
font-weight: 200;
letter-spacing: 1px;
outline: 0;
border: none;
cursor: pointer;
position: relative;
background-color: #fff;
user-select: none;
-webkit-user-select: none;
touch-action: manipulation;
transition: ease-in .2s;
}
.button-52:after {
content: "";
background-color: transparent;
border: 3px solid #fff;
width: 95%;
z-index: -1;
position: absolute;
height: 95%;
bottom: 4px;
right: 8px;
}
.button-52:hover {
transform: scale(1.07)
}
<button class="button-52" role="button">ຂໍ້ມູນເພີ່ມເຕີມ</button>

Use a gradient coloration on the button
#import url('https://fonts.googleapis.com/css2?family=Noto+Sans+Lao:wght#500;700&display=swap');
body {
height: 100vh;
background-color: rgba(8, 41, 85, 1);
display: flex;
align-items: center;
justify-content: center;
}
.button-52 {
font-family: "Noto Sans Lao";
padding: .5rem 2rem;
font-weight: bold;
font-size: 16px;
font-weight: 200;
letter-spacing: 1px;
border: none;
cursor: pointer;
position: relative;
background:linear-gradient(-45deg,#0000 8px, #fff 0);
touch-action: manipulation;
transition: ease-in .2s;
}
.button-52:after {
content: "";
position: absolute;
inset: -6px 8px 4px -6px;
border: 3px solid #fff;
}
.button-52:hover {
transform: scale(1.07)
}
<button class="button-52" role="button">ຂໍ້ມູນເພີ່ມເຕີມ</button>

How to make element stretch vertically and not affect look?

I have a page that looks like this.
//$(document).ready(function() {
// function viewport_height() {
// var window_height = $(window).height();
// $('#wrapper').height(window_height);
// $('#chat-area').height = $(window_height);
// }
// viewport_height();
// $(window).resize(function() {
// viewport_height();
// });
//});

I want the <div class="wrapper"> to resize vertically when height of the device doesn't fit. So when I shrink my browser to a smaller height it will look shrink with it. Also I want the look to stay. I tried to do display: flex; but it just made everything go everywhere. I can't seem to do it. I am trying to do it with JavaScript, but it doesn't work the way it should. Changing the viewport height does not help.

Is this what you are looking for? I wasn't 100% sure from the description
The only css I added are at the bottom of the css section
.chat-area {
display: flex;
flex-direction: column;
height: 100vh;
overflow: hidden;
}
.chat-area header,
.chat-area typing-area {
flex-shrink: 0;
}
.chat-box {
flex-grow: 1;
min-height: auto;
}
The above is the only css I added, the min-height: auto; was to override your original code. Original code is not modified

Here's how to do it with flexbox using this answer.
JSFiddle
body{
height:100vh
}
.wrapper{
height:100%;
}
.chat-area{
display: flex; /* displays flex-items (children) inline */
flex-direction: column; /* stacks them vertically */
height: 100%; /* needs to take the parents height, alternative: body {display: flex} */
}
.chat-box{
flex: 1; /* takes the remaining height of the "container" div */
overflow: auto; /* to scroll just the "main" div */
}

How to disable transformation of search-box when there's input?

I'm not sure how to describe this further, and sorry if it's hard to understand what I"m trying to say.
Hello, firstly I'll like to apologize as I'm a newbie to this. I'd like to know if it's possible to ensure that the search-box in the codesnippet does not transform after I have keyed in some words. In other words it does not go back to its original state which is a circle when there's input.
Thank you in advance!

In your input you can add something like an id and required like this:
<input id=someInput autocomplete="off" name="Search" class="search-txt" type="text" placeholder="Search..." required>
In your css add :
#someInput: :valid { width: 240px;}
and do what you want with invalid:
#someInput :invalid { what you want}
Tested and it works fine, good luck!

This is what javascript is for. To get the desired behavior you could check for a non empty string in the search field. Or you can listen for a click and change the state like I did here. This way it wont shrink when you delete text though.

You can use input:focus to make sure the text box is wide enough when being typed / in focus
I have added js, so that the input box stays same if there any value present, hope this helps you
$('.search-txt').on("input", function() {
if($('.search-txt').val())
{
$('.search-txt').addClass('inputExist');
}
else
{
$('.search-txt').removeClass('inputExist');
}
});

Anchors apply just for simple navigation around the page, for changing tabs etc. you need to add some extra code, something like:
(function($) {
// constants
var SHOW_CLASS = 'show',
HIDE_CLASS = 'hide',
ACTIVE_CLASS = 'active';
switchTab = function(href){
var $link = $('a[href=' + href + ']'),
$tab = $(href);
$('.active').removeClass(ACTIVE_CLASS);
