What is CSS? Why is it needed?

CSS (Cascading Style Sheets) is a style description language that plays an important role in creating beautiful and user-friendly websites.

Why is learning CSS key to being a successful web developer?

  • Appearance: HTML defines textual content, while CSS defines its visual structure, layout, and aesthetics. Without CSS, websites would be less attractive and difficult for users to access. Knowledge of CSS allows us to create a beautiful design, change colors, fonts, positioning of elements and much more.
  • Load Speed: CSS helps reduce code size, which improves page load speed. With a single CSS rule, you can apply styles to all occurrences of a particular tag in an HTML document.
  • User Experience: Well-designed buttons, logically arranged text and user-friendly design make the website more understandable for users. CSS helps improve their website experience.
  • Efficient Development: With CSS, you can apply styles to multiple pages with a single line of code. For example, if you have pages that have the same format, you can use one CSS file for all those pages. If necessary, the design of such pages can be easily changed by changing only the content of the CSS file.
