When to Use CSS vs Javascript

CSS (Cascading Style Sheets) and JavaScript serve different purposes in web development, and their usage depends on the specific requirements of a project. Here’s when to use CSS vs. JavaScript:

1. CSS (Cascading Style Sheets):

   • Use CSS to control the visual presentation and styling of web content.
   • Use CSS for tasks such as setting fonts, colors, margins, padding, layouts, and responsive design.
   • CSS is ideal for maintaining consistent styling across a website and ensuring a cohesive visual identity.
   • CSS is generally more efficient for handling purely presentational aspects of web pages.

2. JavaScript:

   • Use JavaScript for interactivity and dynamic behavior on web pages.
   • Use JavaScript to add functionality like form validation, animations, interactive menus, and real-time updates.
   • JavaScript can be used to manipulate the Document Object Model (DOM) to create, modify, or delete elements on a web page.
   • JavaScript is essential for complex client-side logic and user interactions.

In summary, CSS is primarily used for styling and presentation, while JavaScript is used for adding interactivity and functionality to web pages. It’s common to use both technologies in web development to achieve a well-rounded and feature-rich user experience.
