Rethinking CSS: Powerful New Features and a Streamlined Workflow

March 29, 2024Author: Fabio J Raminhuk

For many years, Sass has been a dominant force in web development, offering a powerful way to manage and organize CSS. However, with the rapid evolution of CSS in recent years, it's worth revisiting the landscape and exploring the exciting new features that are now available natively.


Variables: Centralized Control and Dynamic Power

Once a key advantage of Sass, variables are now an integral part of CSS. You can define properties centrally using the :root selector, ensuring consistency and allowing for easy updates. Unlike Sass variables, CSS variables can be used directly in the browser and even dynamically modified with JavaScript, opening doors for interactive experiences.

Here's an example of defining and using variables in CSS:

:root {
  --button-padding: 10px 20px;
  --button-bg-color: #007bff;
  --button-text-color: #ffffff;
  --button-border-radius: 8px;

.button {
  padding: var(--button-padding);
  background-color: var(--button-bg-color);
  color: var(--button-text-color);
  border-radius: var(--button-border-radius);
  border: none;
  cursor: pointer;
  transition: background-color 0.3s;

CSS Nesting: Organizing Your Styles with Clarity

The ability to nest styles within each other is a game-changer for writing maintainable CSS. Instead of repetitive selectors, nesting allows you to group styles for child elements within the parent selector, leading to a more readable and hierarchical codebase. With browser support exceeding 84%, nesting is becoming a reliable tool for structuring your styles.


Here's an example of using nesting to style blog items:

.blog {
  position: relative;
  padding: 1rem;
  background: var(--neutral-100);

  .blog-item {
    border: 1px solid var(--neutral-200);

    span {
      font-size: 1rem;

Beyond Nesting: Powerful Selectors for Complex Scenarios

While nesting offers a clear benefit, CSS provides even more advanced selector capabilities:

  • :is Pseudo-Class: This powerful selector allows you to target elements matching any of the provided selectors in a list, simplifying complex targeting tasks.
  • :has() Pseudo-Class: Apply styles based on an element's descendants, enabling conditional styling scenarios.

Container Queries: Responsive Design Gets Even Smarter

Container queries represent a significant leap forward in responsive design. They allow elements to adjust their styles based on the size of their container, leading to a more dynamic and adaptable layout.


Here's a basic example of using container queries:

.component {
  --theme: dark;
  container-name: fancy;

@container fancy style(--theme: dark) {
  .fancy {
    /* dark styles. */

.parent-container {
  container-type: inline-size;

  .headline {
    font-size: 2rem;

  @container (width >= 720px) {
    .headline {
      font-size: 2.5rem;

Cascade Layers: Organizing Styles with Granularity

Cascade layers offer a new way to structure your styles by assigning a specific layer (priority) using the @layer at-rule. This allows for better control over the order in which styles are applied, preventing specificity issues.


Sass: Rethinking the Need

While Sass offers features like mixins and functions that aren't yet native in CSS, the overall benefits of native CSS have become compelling. The ease of use, scalability, and powerful new features make it a strong choice for many projects.


Looking Ahead: A Streamlined Future for CSS

The future of CSS is bright, with ongoing development promising even more flexibility and power. By leveraging these new features, developers can create maintainable and performant styles without the need for additional tools in many cases.

This approach can significantly improve workflow efficiency. Consider exploring pre-built code blocks and leveraging the capabilities of your text editor for repetitive tasks.
