CSS (Cascading Style Sheets) are cascading style sheets that we can use to change colors, fonts, margins, backgrounds and other visual properties of HTML elements.
JavaScript is a scripting language that adds interactivity and dynamic features to HTML code. It runs directly in the web browser and allows you to manipulate HTML elements, handle events, interact with the user, send requests to the server and much more. JavaScript can be used to add effects, validate forms, animate, change content on a page and create advanced interactive features.
