Do you want to add a newsletter popup to your website? If so, there’s no need to pay for it! I can guide you through the process of creating one, which will save you both time and money. In this article, you’ll learn how to make a stunning subscribe popup with HTML, CSS, and JavaScript — save time and money while enhancing your web development skills!

Basic HTML Setup

Every excellent web structure begins with HTML — the scaffolding of the web. For our popup, we need a modest setup:

Above, I’m defining a modal with a subscription form. The id Attributes are crucial; they're like unique names for each element that our scripts and styles can refer to.

Scripts

Scripts are essential in bringing life to our static HTML structures on the web. We must add a script tag at the bottom of our body tag to ensure that all HTML elements are loaded before the script runs.

CSS

Cascading Style Sheets (CSS) is a web styling language that adds personality and visual appeal to HTML. We can easily apply styles to our HTML by enclosing them in a <style> tag within the <head> section of our document.

Here, #newsletterModal is initially hidden display: none; — we'll show this modal with JavaScript when the user intends to leave.

JS Functions

Functions are the building blocks of our script. They perform actions such as displaying the modal, closing it, and handling form submissions. The functions below encapsulate our logic, making our code clean and maintainable.

Mousemove

The magic happens with the mousemove event. We will detect if the user's mouse moves toward the browser toolbar, which may indicate an intention to leave the page.

This code snippet waits for the user’s cursor to cross a certain threshold before triggering a popup. The key to a good user experience is subtlety. I wanted the popup to be a gentle invitation, not a forceful intrusion. By tracking the mouse movement, we determine when to show the popup.

Wrapping Up 🎉

It takes some time to combine our HTML structure, style it with CSS, and give it functionality with JavaScript. However, I hope this short guide provides you with the necessary knowledge to build something similar. You can expand the functionality of this popup in countless ways, such as animation, timing delays, cookie-based display logic, and much more.

Following this brief guide can save money on subscription fees and hone your web development skills, enabling you to create even more engaging websites. Keep pushing yourself to code and create, and I can’t wait to see the fantastic results of your hard work. Remember, if you ever need help or have any questions, don’t hesitate to reach out.
