5 things you can do with CSS instead of JavaScript

CSS and JavaScript are increasingly overlapping in functionality as CSS evolves to incorporate features traditionally handled by JavaScript, such as smooth scrolling, dark mode, form validation, and text truncation. This evolution allows developers to achieve complex design and functionality with fewer lines of code and improved browser support. For example, the scroll-behavior property enables smooth scrolling with just one line of CSS, while mix-blend-mode can implement dark mode without extensive JavaScript. New CSS properties like text-overflow and line-clamp address text truncation issues, and scroll snapping offers a native way to control element alignment during scrolling. Additionally, position: sticky simplifies sticky navigation implementations, reducing the need for JavaScript calculations. As these CSS advancements reduce reliance on JavaScript, they can potentially lead to smaller JavaScript bundles and more efficient web performance. However, developers are advised to use these features judiciously to maintain optimal user experience and performance, monitoring their applications with tools like LogRocket. The adoption of @supports media queries further supports progressive enhancement by applying styles only when supported by the browser.
