How to Make Your ALT Text to Tooltip Using Custom JavaScript in Storyline


In this tutorial, we’ll explore an ingenious way to enhance the accessibility features of your Articulate Storyline courses using custom JavaScript. By leveraging the power of JavaScript, you can transform the ALT text of your slide objects into interactive tooltips that appear when you hover your mouse over them. This eliminates the need to create additional states or layers to display tooltips and info guides for your objects and buttons. In just one simple step, you can vastly improve the user experience of your e-learning courses.

Why Enhance Accessibility?

Before we dive into the details, let’s briefly discuss why enhancing accessibility is so important. Accessibility ensures that everyone, regardless of their abilities, can access and benefit from your e-learning content. Making your courses more accessible is not only a matter of compliance but also a step towards inclusivity and a broader audience reach.

Getting Started

Step 1: Access the Slide Master

To begin, open your Articulate Storyline project and access the Slide Master. The Slide Master allows you to make changes that will apply to all slides in your course, ensuring consistency.

Step 2: Create a JavaScript Trigger

Next, you’ll want to create a JavaScript Trigger on the Master Slide that triggers when the timeline starts on a slide. This is the pivotal moment where we infuse your ALT text with JavaScript magic.

Benefits of ALT Text to Tooltip Conversion

Improved User Experience

By converting your ALT text into tooltips, you provide your learners with a more engaging and interactive experience. Tooltips are a user-friendly way to offer additional information without cluttering the screen.

Accessibility Compliance

This approach aligns with accessibility guidelines, making your courses compliant with standards like WCAG (Web Content Accessibility Guidelines). Compliance is not only ethically important but may also be legally mandated in some cases.

Reduced Development Time

You no longer need to create separate objects or layers for tooltips, saving you valuable development time. This streamlined approach is especially helpful when working on complex e-learning projects.

Easy Updates

Making changes or updates to your tooltips is now a breeze. You can update the ALT text, and the tooltips will automatically reflect those changes, ensuring content accuracy.


The ALT text to tooltip conversion is mobile-responsive, providing a consistent user experience across different devices.


In just a few steps, you’ve unlocked the potential of your ALT text by converting it into tooltips using custom JavaScript. This simple yet powerful solution enhances accessibility, improves the user experience, and simplifies course development. Your learners will appreciate the interactivity, and you’ll appreciate the time and effort saved. So, why wait? Give your Articulate Storyline courses a touch of JavaScript magic today!
