Why we stopped using CSS in JS?

In recent years, the practice of using CSS-in-JS has gained popularity among developers as a way to style their web applications. However, there has been a growing movement of developers who are pushing back and advocating for a return to traditional CSS stylesheets.

The use of CSS-in-JS has its benefits, but it also comes with some drawbacks and challenges that have caused many developers to rethink its use. In this article, we will explore the reasons why some developers have abandoned CSS-in-JS and returned to using traditional CSS stylesheets for their web development projects.

Breaking Up with CSS-in-JS: Exploring a New Path for Web Development

Web development has come a long way since the days of simple HTML and CSS websites. With the advent of JavaScript frameworks and libraries, developers have been able to create complex, interactive web applications that feel like native desktop apps. One of the most popular techniques for styling these apps is CSS-in-JS, which allows developers to write CSS directly in their JavaScript code.

The Pros and Cons of CSS-in-JS

CSS-in-JS has become popular for a reason. It offers a number of benefits over traditional CSS:

  • Scoped styles: CSS-in-JS allows developers to scope their styles to individual components, avoiding the cascading nature of traditional CSS. This makes it easier to manage styles and avoid conflicts.
  • Dynamic styles: Since CSS-in-JS is written in JavaScript, developers can easily create dynamic styles based on user input or other variables.
  • Reduced file size: CSS-in-JS eliminates the need for separate CSS files, reducing the number of requests the browser needs to make.

However, CSS-in-JS also has its downsides:

  • Learning curve: If you’re not already comfortable with JavaScript, learning CSS-in-JS can be a steep curve.
  • Performance: While CSS-in-JS can reduce file size, it can also introduce performance issues if not implemented properly, since styles are generated on the fly.
  • Maintenance: Since styles are tightly coupled with the JavaScript code, making changes to styles can be more difficult and error-prone.

A New Path for Web Development?

Given the pros and cons of CSS-in-JS, some developers are exploring alternative approaches. One of these approaches is CSS Modules.

CSS Modules is a system for writing modular, scannable, and reusable CSS. It allows you to write traditional CSS files, but with the added benefit of scoping and modularity. CSS Modules generates unique class names for each module, avoiding naming conflicts and allowing for easy composition of styles. It also supports dynamic styles through the use of placeholders.

While CSS Modules doesn’t offer the same level of integration with JavaScript as CSS-in-JS, it does offer a simpler, more predictable approach to styling. And since it’s based on traditional CSS, it’s easier to learn and maintain.

The Bottom Line

As with any technology, the choice between CSS-in-JS and CSS Modules depends on the specific needs of your project. If you’re working on a complex, dynamic application with a team of experienced JavaScript developers, CSS-in-JS may be the right choice. But if you’re looking for a simpler, more predictable approach to styling, CSS Modules is worth considering.

Ultimately, the goal of any development approach should be to create maintainable, scalable code that meets the needs of the project and the users. Whether you choose CSS-in-JS, CSS Modules, or another approach entirely, keeping that goal in mind will ensure your success as a web developer.

Exploring the Downsides of CSS-in-JS: A Comprehensive Guide

CSS-in-JS has been a popular topic in the front-end development community, with its proponents citing its benefits like modularity and ease of use. However, it’s important to consider the downsides of this approach as well. In this comprehensive guide, we’ll explore the potential pitfalls of using CSS-in-JS.

What is CSS-in-JS?

CSS-in-JS is an approach to styling web applications where CSS is written in JavaScript files. This allows for more modularity and ease of use, as styles can be written and applied on a component-by-component basis.

Downsides of CSS-in-JS

Increased bundle size

One of the most significant downsides of CSS-in-JS is that it can increase the bundle size of your application. While the modularity of CSS-in-JS can be beneficial, it can also lead to a lot of duplicate code.

Performance concerns

CSS-in-JS can also have performance implications. When styles are written in JavaScript, they must be parsed and executed by the browser, which can be slower than traditional CSS files. This can lead to slower load times and less performant applications.

Learning curve

While CSS-in-JS can be easy to use for some developers, it may require a learning curve for others. It can be difficult to learn a new syntax and approach to styling applications, particularly for those who are used to traditional CSS files.

Debugging difficulties

Debugging CSS-in-JS can also be more difficult than traditional CSS files. Since styles are written in JavaScript, it can be harder to pinpoint issues and track down bugs.

SEO concerns

Finally, CSS-in-JS can have SEO implications. Since styles are written in JavaScript, they may not be as easily crawlable by search engines. This can lead to lower search engine rankings and less visibility for your application.

Why JavaScript is Essential for Dynamic Web Design: A Comparison with CSS

JavaScript and CSS are two important technologies used in web design. While CSS is used to style and layout web pages, JavaScript is essential for creating dynamic, interactive web pages. In this article, we will discuss why JavaScript is essential for dynamic web design and compare it with CSS.

What is JavaScript?

JavaScript is a programming language that is used to create interactive web pages. It is a client-side scripting language, which means that it runs on the user’s web browser. JavaScript can be used to add interactivity, animations, and other dynamic features to a web page.

Why is JavaScript important for dynamic web design?

JavaScript is essential for creating dynamic web pages that respond to user actions. It can be used to create interactive forms, pop-up windows, and other elements that enhance the user experience. JavaScript can also be used to create animations, slide shows, and other visual effects that make a web page more engaging.

JavaScript is also important for creating responsive web design. With JavaScript, you can create web pages that automatically adjust to different screen sizes and devices. This is important in today’s world of mobile devices, where more and more people are accessing the internet on their smartphones and tablets.

Comparison with CSS

While both JavaScript and CSS are important for web design, they serve different purposes. CSS is used for styling and layout, while JavaScript is used for interactivity and dynamic features.

CSS is used to control the visual appearance of a web page. It can be used to set the font size, color, and spacing of text, as well as the size and position of images, videos, and other elements on the page. CSS can also be used to create responsive web design, by using media queries to adjust the layout of a web page based on the size of the screen.

JavaScript, on the other hand, is used for creating dynamic and interactive web pages. It can be used to create animations, slide shows, and other visual effects that make a web page more engaging. JavaScript can also be used to create pop-up windows, interactive forms, and other elements that enhance the user experience.

CSS is used for styling and layout, while JavaScript is essential for creating dynamic, interactive web pages. By combining these two technologies, web designers can create engaging, responsive web pages that provide an optimal user experience.

CSS-in-JS: Solving the Problem of CSS Scalability and Maintenance

CSS scalability and maintenance have been a problem for web developers for a long time. The traditional method of writing CSS involves creating a separate file for CSS and linking it to the HTML file. This method works fine for small projects, but as the project grows, it becomes difficult to manage the CSS file. This is where CSS-in-JS comes in.

What is CSS-in-JS?

CSS-in-JS is an approach to styling web applications that allows developers to write CSS code inside JavaScript code. In other words, CSS-in-JS allows developers to create and manage CSS styles using JavaScript.

The concept of CSS-in-JS is not new, but it has gained popularity in recent years. The approach has been adopted by many front-end libraries and frameworks such as React, Vue, and Angular.

Benefits of CSS-in-JS

CSS-in-JS offers several benefits over traditional CSS styling. One of the main benefits is that it solves the problem of CSS scalability and maintenance. With CSS-in-JS, developers can write modular CSS code that is specific to each component. This makes it easier to manage and update the CSS code as the project grows.

Another benefit of CSS-in-JS is that it allows developers to write dynamic styles based on the state of the application. For example, developers can write styles that change based on user interactions or data changes.

CSS-in-JS also helps to improve the performance of web applications. With traditional CSS styling, the browser has to download the CSS file before rendering the HTML content. With CSS-in-JS, the CSS code is embedded in the JavaScript code, which means that the browser can download the JavaScript file and render the HTML and CSS together.

Popular CSS-in-JS Libraries

There are several CSS-in-JS libraries available for web developers. Some of the popular libraries include:

  • Styled Components: A popular CSS-in-JS library for React applications. Styled Components allows developers to write CSS code using tagged template literals.
  • Emotion: Another popular CSS-in-JS library for React applications. Emotion allows developers to write CSS code using JavaScript objects or template literals.
  • JSS: A CSS-in-JS library that can be used with any JavaScript framework. JSS allows developers to write CSS code using JavaScript objects.

While the idea of using CSS in JS may seem appealing at first, it has proven to be more trouble than it’s worth. The benefits of separating concerns and maintaining a clear separation of styles from logic far outweigh any perceived benefits of using CSS in JS. Additionally, using traditional CSS allows for better accessibility, easier debugging, and a more efficient workflow. While it may take some time to adjust to a new way of writing styles, the end result is a more maintainable, scalable, and streamlined codebase. As with any technology, it’s important to evaluate whether it truly serves the needs of your project before jumping on the latest bandwagon.
