How to Show a Div After 800px Scroll Using Pure JavaScript

Scrolling down a webpage and losing track of your position can be frustrating, especially if you want to go back to the top. Fortunately, a common solution to enhance user experience is to add a button that allows users to quickly scroll back to the top. In this guide, you’ll learn how to automatically display a button after scrolling down 800 pixels using purely JavaScript.

The Problem: How to Show a Button After Scrolling Down

You want to create a button that appears after the user has scrolled down a specific distance (in this case, 800 pixels). This button, when clicked, will scroll the user back to the top of the page. The goal is to enhance usability without relying on any external libraries or frameworks—just plain JavaScript.

The HTML Setup

Here’s a simple HTML structure for our button:

This button will be styled and made functional with JavaScript and CSS.

The Solution: Implementing the Scroll-Triggered Button

To achieve the desired functionality, follow these steps:

Step 1: Creating a Hidden Class in CSS

First, we need to define a CSS class that will keep our button hidden initially. By using the visibility property, we can control when the button appears.

Step 2: Defining JavaScript Functionality

Now, let’s add the JavaScript that will manage the button’s visibility based on the scrolling action. Here’s how it works:

Select the Button Element: We will select the button we created in the HTML.

Add Click Event: We will make the button scroll the user back to the top when clicked.

Listen for Scroll Events: We will continuously check how far the user has scrolled down the page and show or hide the button accordingly.

Here’s the complete JavaScript code:

Step 3: Testing Your Implementation

Scroll Down: As you scroll down the page, after reaching 800 pixels, the button should appear.

Scroll Up: If you scroll back up above 800 pixels, the button should disappear.

Conclusion: Enhanced User Experience with Simple JavaScript

Implementing a button that appears after scrolling a certain distance can greatly enhance website usability. With just a few lines of code in JavaScript and CSS, you can improve navigation for your users.

Try this code in your next web project, and watch users appreciate the ease of returning to the top of the page with a simple click. Happy coding!
