At first glance, CSS appears simple, but mastering it requires effort and practice. Advanced topics such as Flexbox, Grid, responsive layouts, animations, and browser-specific adjustments can be confusing for beginners. Writing efficient and well-organized CSS is a skill that takes time to develop.

When working on large-scale websites, managing CSS can become difficult. A single CSS file may contain thousands of lines of code, and even a small change can cause unexpected design issues across multiple pages. Without proper structure and organization, CSS can quickly become messy and hard to maintain. This is why many developers rely on frameworks and preprocessors to manage complexity.

CSS is purely a styling language, which means it has no direct security controls. While CSS itself cannot harm a system, it can sometimes be misused along with HTML and JavaScript for malicious activities such as clickjacking or misleading designs. Therefore, developers must use CSS responsibly and combine it with secure coding practices.

Not all browsers support CSS in the same way. Some advanced properties or features may display differently depending on the browser or its version. For example, older browsers often have trouble rendering modern CSS properly. This forces developers to test their designs across multiple browsers and sometimes write additional code to ensure consistent results.
