Difference between CSS and SCSS

CSS has been the best choice of developers over the last few years in web creation. However, since the production of SASS, its use has been significantly reduced. SCSS is an enhanced version of the SASS; therefore, it is more widely used these days. In this article, we will discuss the difference between the CSS and SCSS. Before making the comparison, we will know about the CSS and SCSS.

What is CSS?

Cascading Style Sheet (CSS) is a scripting language used to develop web pages. It is also used to style web pages to makes them attractive. It is the most popular web technology widely used with HTML and JavaScript. The extension of the CSS is .css.

Håkon Wium Lie first proposed the CSS on 10 October 1994, and the first W3C CSS Recommendation (CSS1) was issued in 1996. It is designed to allow the separation of content and presentation, like colors, fonts, and layout. The separation of content and presentation may improve the content usability and give more flexibility to control the presentation specification. It allows many web pages to share formatting by specifying the associated CSS in a separate .css file and minimizing complexity and duplication in the structural context.

Advantages of CSS

Various advantages of CSS are as follows:

  1. Consistency: CSS helps to build a consistent structure that web designers can use to construct other pages. Because of this, the web designer's working efficiency also improves.
  2. Ease of Use: It is very easy to learn CSS and facilitates the creation of websites. All codes are put on one page, meaning it would not involve going through multiple pages to improve or edit the lines.
  3. Website Speed: Typically, the code used by a website may be up to 2 or more pages. But with CSS, that's not the code, and thus the web site database remains uncluttered, avoiding any website loading problems.
  4. Multiple Browser Support: Many browsers support CSS. It is consistent with all the web browsers on the internet.
  5. Transfer Size: It decreases the size of the file transfer. Therefore, the file transfer is very quick.
  6. Web-Page crawl: CSS helps to allow SEO for the website. Adding CSS to the web pages makes it easier for the search engine to find the website in the search result.

Disadvantages of CSS

Various disadvantages of CSS are as follows:

  1. Many CSS versions: As opposed to other versions like HTML or JavaScript, CSS has various version such as CSS1, CSS2, CSS2.1, and CSS3.
  2. Fragmentations: There's a possibility with the CSS that we work with one browser, and we will not be able to work with other web browsers. Thus, web developers need to verify compatibility by running the software through various browsers before the website is set up.
  3. Complications: With the use of third-party tools like Microsoft FrontPage, CSS might become complicated.
  4. Lack of Security: CSS is a system based on open text, so it has no built-in security mechanism that stops it from being overridden. Anyone can alter the CSS file and modify the links by accessing its read and write operations.
  5. Cross-Browser Issues: It is simple to introduce initial CSS changes on a site at the developer's end. Although the modifications have been made, if the CSS shows identical alteration effects on all browsers, the user will have to confirm compatibility. It is simple because CSS operates on various browsers differently.

What is SCSS?

SCSS stands for the Sassy Cascading Style Sheets. The more advanced variant of CSS is SCSS. It was created by Chris Eppstein and Natalie Weizenbaum and designed by Hampton Catlin. It is also referred to as Sassy CSS due to its advanced features. It is a pre-processor language that is compiled or interrupted into the CSS. It has a file extension of .scss.

We may add several extra features to CSS using SCSS, including variables, nesting, and many more. All of these extra features may make writing SCSS much simpler and quicker than writing the standard CSS. SCSS may use the CSS code and function. SCSS is entirely compliant with the CSS syntax, though also supporting the full power of SASS.

Advantages of SCSS

Various advantages of SCSS are as follows:

  1. It helps users to write clean, quick, and less CSS code in a program structure.
  2. There are fewer codes in it so that we can write CSS faster.
  3. SCSS offers nested so that we can use the nested syntax and useful functions, including color manipulation, math functions, and many other functions.
  4. It consists of variables that help reuse the values as many times as in the CSS.
  5. All versions of CSS are compatible with it. So, we can use any CSS library available.
  6. SASS is versatile with feedback, but any good developer would prefer the inline documentation available in SCSS.

Disadvantages of SCSS

Various Disadvantages of SCSS are as follows:

  1. Debugging: Pre-processors have a compilation stage that makes the CSS meaningless code lines when attempting to debug the code. But it's twice as difficult to debug as programming, making it a big disadvantage.
  2. Understanding: Even if the pre-processors have become popular, there is a knowledge gap in CSS.
  3. Large CSS Files: The source files may be tiny, but the CSS produced may be huge.
  4. Loss of benefits: Using SASS can cause the browser's built-in element inspector to lose its benefits.

Key Differences between the CSS and SCSS

Here, we will discuss the main differences between the CSS and SCSS.

  1. SCSS includes all of the CSS features and other features that are not available in CSS, making it a strong alternative for developers to use it.
  2. CSS is a style language that is used to style and create web pages. While SCSS is a particular type of file for SASS, it used the Ruby language, which assembles the browser's CSS style sheets.
  3. SCSS contains advanced and modified features.
  4. SCSS is more expressive than the CSS. SCSS uses fewer lines in its code than CSS, which makes loading the code easier.
  5. It promotes proper nesting of rules. Nesting is not assisted by regular CSS. Inside another class, we cannot write a class. It brings a readability issue as the project gets larger, and the layout doesn't look good.
  6. Various style sheets may be used on a single page by some simple CSS line code changes. It has benefits for usability and the ability to customize a website or site to various target devices.
  7. We may include the various features to the code in the form of variables, nesting, and selectors with SCSS. In contrast, these features are not present in the CSS.
  8. The SCSS syntax uses indentations that are not present in CSS.
  9. SCSS helps us to use the operators to do the math operations. Inside our code, we can make simple calculations for better performance.
  10. The knowledge of SCSS helps to customize Bootstrap 4.

Head to Head Comparison between CSS and SCSS

Here, we will discuss the head-to-head comparison between CSS and SCSS in the tabular form:

Functions It contains common functions. It contains more advanced features.
Code It uses an extensive line of codes. It uses fewer lines in its code than the CSS.
Nesting Rules Nested rules are not assisted in Regular CSS. It promotes properly nested rules.
