In the rapidly advancing world of technology, web design has become an integral part of our daily lives. Whether you’re browsing a news website, shopping online, or scrolling through your social media feed, everything you see is the result of multiple technologies working together to create an attractive and visually appealing design. One of the most important of these technologies is CSS (Cascading Style Sheets), which is considered the backbone of modern web design.
What is CSS?
CSS stands for “Cascading Style Sheets,” and it is a language used to style and design web pages. If we compare HTML to the building blocks that define the structure of a webpage, CSS acts as the tool that gives this structure its final look and feel. In other words, while HTML creates the basic elements like headings, paragraphs, and images, CSS is responsible for determining how these elements appear on the screen—color, size, font, spacing, and even the positioning of elements relative to one another.

Why is CSS Important?
Before CSS, developers relied entirely on HTML to create designs, resulting in complex and disorganized code. As websites became more intricate, managing design using only HTML became increasingly challenging. This is where CSS stepped in, offering an innovative solution:
- Separation of Design and Content: Thanks to CSS, developers can separate design (form) from content (text). This makes the code more organized and easier to maintain.
- Ease of Modification: If you need to change the background color of an entire website, you can do so simply by modifying a single line in the CSS file instead of searching through every HTML page.
- Improved User Experience: CSS enables the creation of responsive designs, meaning the website will look great on any device, whether it’s a smartphone, tablet, or desktop computer.
- Multilingual Support: CSS can be used to customize designs based on the language being used, enhancing the global accessibility of websites.
How Does CSS Work?
CSS operates on a system of rules, where you specify the element you want to style and then apply a set of properties to it. For example, if you want to change the color of all main headings, you can write a rule that says: “Make all main headings blue.”
Levels of Using CSS
CSS can be applied in several ways:
- Inline CSS: Adding the

attribute directly within an HTML element. - Internal CSS: Writing the code inside a
