The Mastering Styling in React: An Introduction to CSS Modules

 

Introduction

In the dynamic world of web development, the introduction of React has fundamentally revolutionised the way we approach frontend design. As the quintessential library for creating sleek, responsive, and scalable user interfaces, React’s ability to cohesively marry JavaScript and HTML through JSX syntax has captured the attention of developers globally.

However, effective styling, which is a significant aspect of UI design, can pose a challenge. This is where the magic of CSS comes into play. In this blog post, we will delve deep into the world of React CSS and CSS modules, helping you manoeuvre the styling maze with finesse and expertise.

CSS in React

At the heart of styling in React lies CSS, or Cascading Style Sheets. This design language breathes life into your raw HTML elements, providing them with colour, movement, and personality. Traditionally, CSS is embedded directly into HTML or externally linked. However, when utilising React, we use a slightly different method.

One can incorporate CSS into a React project by using either inline styles, CSS stylesheets, or CSS modules. Of these, CSS modules have emerged as the most popular approach due to their capacity for local scope and code reusability.

Understanding React CSS Modules

CSS modules can be regarded as an extension of CSS. They encapsulate styles into standalone modules, providing each component with unique, locally scoped CSS. This means the styles applied to a component won’t accidentally bleed out and affect other components, solving the problem of global CSS.

React module CSS enables you to write CSS that lives inside JavaScript modules. You might ask, “How does that work?” Essentially, each CSS module comprises a CSS file where all class names and animation names are inherently scoped locally.

To use CSS modules in a React project, you need to install the ‘react-css-modules’ library. Then, when you import a CSS module, it maps the styles to a JavaScript object.
