What is the difference between javascript and CSS?

CSS is used for the design of a webpage or webpages itself. How everything is placed, colors used, styles, ect. While Java script is used to design the interactive parts of a webpage. Rotation of photos, text and more. It is highly used to create interactivity for the end user.

As the bootstrap website states, “Bootstrap is the most popular HTML, CSS, and JS framework for developing responsive, mobile first projects on the web.” It bundles Javascript plugins with an extensive list of components.
