create dynamic text animations in Articulate Storyline using external JavaScript libraries SplitType.js and GSAP.

SplitType.js is used to split text into individual characters, and GSAP is used to animate the characters. The code provided in the blog post can be used to create a simple elastic stretch animation, but the possibilities are endless.

To use the code, you will need to create a text box and a button in your Storyline project. The text box should be given the accessibility name "heading4" and the button should be given the accessibility name "button4." Once you have added the code to your project, you can customize the animation by changing the values of the parameters in the GSAP timeline.
