Getting started:
First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.
The Main Interface
This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.

This code contains the script of the application. This code will dynamically change the text size when the slider is moved. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.
