CSS (Cascading Style Sheets) is a stylesheet language used to control the presentation and layout of HTML elements on a web page. While HTML is used to define the structure and content of a webpage, CSS is responsible for how that content looks—its colors, fonts, spacing, positioning, responsiveness, and overall design.

Reasons We Use CSS

1
To separate content (HTML) from design (CSS), making code cleaner and easier to maintain.
2
To apply consistent styling across multiple pages of a website.
3
To enhance the visual appearance of web pages with colors, layouts, fonts, and animations.
4
To support responsive design and ensure that web pages work on various devices and screen sizes.
5
To improve user experience by making interfaces more attractive and usable.
