What is CSS

CSS (Cascading Style Sheets) is a style sheet language used to describe web pages layout, appearance and style. It allows web developers to control how elements such as text font, size, color, background color, borders, spacing, and positioning are displayed.

Role in web pages

CSS plays a vital role in web pages:

  • Separates content and Styling: CSS separates the content of a web page from its style, allowing developers to easily change the appearance of a web page without changing the underlying HTML code.
  • Style Consistency: CSS allows consistent styling to be applied throughout your website, ensuring all pages have the same look and feel.
  • Improve accessibility: CSS can help improve the accessibility of web pages, making them easier to use for people with disabilities. For example, text size and color can be adjusted to improve readability.
  • Responsive Design: CSS allows the creation of web pages that respond to different devices and screen sizes. This is important to provide a consistent user experience across devices such as desktops, laptops, tablets, and smartphones.
  • Performance Optimization: By using CSS, developers can reduce web page file size, thereby improving loading speed and performance.
