First we need to create basic starting template with required links of CSS CDN links in head section of HTML file.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<div class="tags-container">

Let's Move On Javascript
First of all we need to Retrieve element in JavaScript using queryselector method that allows you to select and retrieve elements from the DOM(Document Object Model) .
after Retrieve Elements from DOM Define MaxTag . How Many Tags User Can Add Maximum . After That We need to Create an Empty Array for store tag.
Next Step Create Functions for CountingTags , CreateTags , Add and Remove Tag . After Creating Functions Apply Validations Like whether Maximum Tags limit crossed or not.
const ul = document.querySelector("ul"),
input = document.querySelector("input"),
tagNumb = document.querySelector(".details span");
let notes = document.querySelector(".details p");
let maxTags = 20,
tags = [];
countTags();
createTag();
function countTags(){
input.focus();
tagNumb.innerText = maxTags - tags.length;
}
function createTag(){
ul.querySelectorAll("li").forEach(li => li.remove());
tags.slice().reverse().forEach(tag =>{
let red=Math.random()*255;
let green=Math.random()*255;
let blue=Math.random()*255;
let liTag = `<li style="background-color:rgba(${red},${green},${blue},0.3) ;">${tag} <i class="fa fa-multiply" onclick="remove(this, '${tag}')"></i></li>`;
// alert(randomBgColor())
ul.insertAdjacentHTML("afterbegin", liTag);
});
countTags();
valid();
}
function remove(element, tag){
let index = tags.indexOf(tag);
tags = [...tags.slice(0, index), ...tags.slice(index + 1)];
element.parentElement.remove();
countTags();
valid();
}
function addTag(e){
if(e.key == "Enter"){
let tag = e.target.value.replace(/\s+/g, ' ');
if(tag.length > 1 && !tags.includes(tag)){
if(tags.length < maxTags){
tag.split(',').forEach(tag => {
tags.push(tag);
createTag();
});
}
}
e.target.value = "";
}
}
input.addEventListener("keyup", addTag);
const removeBtn = document.querySelector(".details button");
const container = document.querySelector(".tags-container");
removeBtn.addEventListener("click", () =>{
if(tags.length == 0){
container.classList.add("custom-anim")
// For Remove Shake Effect
setInterval(function(){
container.classList.remove("custom-anim")
},1400)
}
else{
tags.length = 0;
ul.querySelectorAll("li").forEach(li => li.remove());
countTags();
}
});
function randomBgColor(){
let red=Math.random()*255;
let green=Math.random()*255;
let blue=Math.random()*255;
return `rgba(${red},${green},${blue},0.3)`
}
// Added
function valid(){
if( maxTags <= tags.length){
ul.style.borderColor="red";
notes.style.color="red"
}
else{
ul.style.borderColor="#a6a6a6";
notes.style.color="black"
}
}
