How Do I Pop Up Webflow?

Welcome to this tutorial on how to create a pop-up in Webflow! Pop-ups are a great way to grab your user’s attention and provide important information or call-to-action. In this article, we will go through step-by-step instructions on how to create a pop-up using HTML and CSS in Webflow.

Step 1: Setting up the HTML Structure

First, let’s start by creating the HTML structure for our pop-up. We will use a <div> element with a unique ID to represent the pop-up container.

Inside the container, we will have the content that we want to display within the pop-up. Here’s an example:

<div id="popup" class="popup-container">
  <div class="popup-content">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
    <a href="#" class="btn">Sign Up</a>

The above code creates a pop-up container with an ID of “popup”. Inside the container, we have a pop-up content which includes a heading (<h3>), paragraph (<p>), and a button (<a>). Feel free to modify this structure according to your needs.

Step 2: Styling the Pop-Up with CSS

Now that we have our HTML structure in place, let’s style our pop-up using CSS. We will use CSS to position the pop-up, add animations, and control its visibility. Here’s an example of how you can style the pop-up:

.popup-container {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0, 0, 0, 0.5);
  display: flex;
  justify-content: center;
  align-items: center;
}popup-content {
  background-color: #fff;
  padding: 20px;
}popup-content h3 {
   font-size: bold;
   color: #333;
}popup-content p {
   font-size: italic;
}btn {
   background-color: #007bff;
   color: #fff;
   padding: .5rem .75rem;

In the above CSS code, we set the position of the container to fixed, which ensures that it stays in place even when the user scrolls. We also set the top, left, width, and height properties to cover the entire viewport. The background color is set to a semi-transparent black using the rgba color format.

We also use flexbox properties to center the content within the pop-up container. The content itself is styled with a white background color and some padding for spacing.

Step 3: Adding Interactivity with JavaScript (Optional)

If you want to add interactivity to your pop-up, such as showing or hiding it based on user actions, you can use JavaScript. Here’s an example of how you can achieve this:

// Get the pop-up container element
var popup = document.getElementById("popup");

// Function to show the pop-up
function showPopup() { = "flex";

// Function to hide the pop-up
function hidePopup() {
  popup.display = "none";

In the above JavaScript code, we use the getElementById() method to get a reference to the pop-up container element. We then define two functions – showPopup() and hidePopup().

The showPopup() function sets the display property of the pop-up container to “flex”, making it visible. The hidePopup() function sets the display property to “none”, effectively hiding the pop-up.

Step 4: Triggering the Pop-Up

To trigger the pop-up, you can use various techniques such as a button click or a timed delay. Here’s an example of how you can trigger the pop-up using a button click:

// Get the button element
var btn = document.getElementById("trigger-btn");

// Add event listener for button click
btn.addEventListener("click", showPopup);

In this example, we use getElementById() again to get a reference to the trigger button element. We then use addEventListener() to attach a click event listener to the button. When clicked, it will call the showPopup() function, displaying our pop-up.


You have successfully created a pop-up in Webflow using HTML, CSS, and optionally JavaScript. Experiment with different styles and animations to make your pop-ups more visually engaging and interactive.

Remember to test your pop-up across different devices and browsers to ensure a consistent experience for your users. Happy coding!
