As I said it is an automatic and manual model pop-up created by JavaScript. First I used a gradient background color on the page. 

Then I created a button that can be used to manually view this Modal Popup JavaScript. Also, when you load that page, this window will automatically appear in front of you.

There is a Cancel button to hide Modal Popup. This window contains an image, a heading, some text, and a cancel button.

How to Create a Modal popup in JavaScript

If you know basic HTML, CSS, and javascript then you can easily create this modal popup in javascript. First I added basic information using HTML. 

Then I designed it with CSS and arranged it to open it automatically. Finally, the popup button and the cancel button have been activated by JavaScript.

Step 1: Create popup button

We first created a button using the following HTML and CSS code that will act as a popup button.

<button class=”btn open-modal” id=”open-modal”>Open Modal</button>

I designed the webpage using the following CSS. The linear-gradient background color is used on the page.

* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
body {
  min-height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  font-family: “PT Sans”, sans-serif;
  background-image: linear-gradient(to top, #fbc2eb 0%, #a6c1ee 100%);
designed the webpage

Now I have designed the button. Depending on the size padding of this button.

.btn {
  font-family: “PT Sans”, sans-serif;
  font-size: 1.2rem;
  padding: 1rem 2.5rem;
  cursor: pointer;
  border: none;
.open-modal {
  background: #fff;
  border-radius: 5px;
  border: 1px solid transparent;
  box-shadow: 0 5px 10px 2px rgba(0, 0, 0, 0.2);
  transition: all 0.2s linear;
.open-modal:hover {
  box-shadow: none;
  background: rgba(255, 255, 255, 0.5);
  border-color: #fff;
Create popup button
