Sass Interview Questions

SASS stands for Syntactically Awesome Style Sheets. It is a style sheet language, in other words, it is a scripting language which is compiled into CSS (Cascading Style Sheets).In short, SASS is the CSS pre-processor, and it is a more stable and powerful CSS extension. SASS is an open-source pre-processor which is coded in Ruby. We are mentioning some of the SASS Interview Questions that will give you the detail of the topic.

Development History of SASS

Natalie Weizenbaum developed SASS, and Hampton Catlin designed it. SASS was developed to reduce the coding time by using only a few codes for ant HTML elements.

SASS was developed in such a way that it is compatible with any CSS because it contains all the features of CSS and secondly the document it provides is in a structured format only.

Get into complete detail and knowledge of SASS through SASS advanced interview questions.

Advantages

  • Stable and powerful than CSS
  • Open-Source Pre-processor
  • Can be used on all the versions of CSS
  • Possible to use the nested syntax and useful functions. For example -Mathematics, Colour Manipulation.

Most Frequently Asked Sass Interview Questions

Here in this article, we will be listing frequently asked Sass Interview Questions and Answers with the belief that they will be helpful for you to gain higher marks. Also, to let you know that this article has been written under the guidance of industry professionals and covered all the current competencies.

Q1. What is Sass? Explain
Answer

SASS stands for Syntactically Awesome Style Sheets. SASS is the extension of the CSS which describes the document in a structured format. SASS provides more powerful syntax than CSS.

Q2. Is bootstrap LESS or SASS? Explain
Answer

SASS and LESS both are the preprocessor of CSS that enhance the development of CSS but SASS is powerful as compared to LESS. Bootstrap provides a whole framework for creating the user interfaces that include the widgets, the grid layout system, the typographic styling, the Interactive Menu bars and many more. Bootstrap have used many preprocessors in the past for the CSS source code but out of SASS and LESS, Bootstrap uses LESS pre-processor and it has also included various customisations by using the fewer variables and the fewer components.

 

But Recently BOOTSTRAP 3 has also given the SASS codebase as an alternate option but BOOTSTRAP 4 is being built completely on SASS codebase and this is the first time Bootstrap has using SASS.

Q3. Who introduced SASS?
Answer

SASS (Syntactically Awesome Style Sheets) was developed by Natalie Weizenbaum and it was designed by Hampton Catlin.

Q4. What is the difference between Sass and CSS? Explain
Answer
S.no CSS SASS
1. Codes are Long Code is Short
2. Unstructured Document Structured Document
3. Nesting:-Code Block are not Nested Nesting:- Allow the nested code to be included in each other
4. Suitable for small web applications Suitable for small web applications as well as large user interfaces
5. Offers less flexibility Has an ability to add mixin, functions, variable etc
6. Multiple stylesheets cannot be joined Multiple Stylesheets can be joined into only one Style Sheet
7. Darken and Lighting Functions are not available Darken and Lighting Functions are available
8. Mathematical functions are not available Mathematical functions are available
Q5. How many ways can we use SASS? Please explain
Answer

SASS (Syntactically Awesome Style Sheets) can be used in the following three ways.

  • SASS can be used as a Command Line Tool
  • SASS can be used as a Ruby Module
  • SASS can be used as a plugin for the Rack Enable Network
Q6. Explain the features of SASS?
Answer

Here are some of the feature of SASS:-

  • SASS is more stable, compatible and powerful with versions of CSS.
  • SASS is a pre-processor of CSS and is based on the JavaScript.
  • SASS is called as syntactic sugar for CSS because SASS has found an easier way for the user to read or express the things more clearly while coding
  • SASS uses its own syntax and then it gets compiles to readable CSS.
  • SASS is an open source pre-processor.
  • Nesting is one of the most important features of SASS. As a result of Nesting, the repetitions of the code is almost negligible and it is easier to maintain a document.
  • In SASS the variables start with $ and as result handling the global values like colours, breakpoints and fonts has become a lot easier.
Q7. What is the difference between SCSS and Sass?
Answer
S.no SCSS SASS
1. It is a New Syntax It is an original and the old syntax
2. The file is saved with the extension .scss The file is saved with the extension .SASS
3. In a code the use of semicolon and bracket{} is compulsory. In a code, the use of semicolon and bracket{} is not allowed
4. There is no strict indentation There is a strict indentation
5. Easier to learn Difficult to learn as compared to SCSS
Q8. What is the use of Sass @import function?
Answer

SASS @import directive is used to include one stylesheet inside another stylesheet and in other words, we can say that it imports the .SASS and .scss files.The location of the stylesheet can either be in the same server or it is written with the URL to the directory of another server. For Example:-

  • @import "test.css";
  • @import "css/test.css";
  • @import url("http://check.com/css/test.css");
Q9. What are the advantages of Sass? Explain
Answer
  • SASS provides fewer codes and saves a lot of time of the coder
  • SASS works with all the versions of CSS
  • Project is organised
  • SASS allows defining the variables which have to be reused throughout the code.
  • With the use of the @extend function same style can be copied to the other classes also and there is no need to rewrite the code again.
Q10. Which is better, Sass or Less? Explain
Answer
  • Looping:- LESS allow the loops but that is only through the recursive calling and this can lead to a little tricky coding and maintaining this code will be a difficult job and SASS there are control derivative like @if, @for, @each and @while which are easier to use
  • Cross Browser Support:- In SAAS, CSS transitions can be implemented by writing just one CSS rule and it adds up all the browsing rules for the coder.
  • Mathematical Operations:-SASS performs more accurate mathematical operations than LESS
  • Compilation Time:-Compilation time of SASS is less than LESS
  • Documentation:-SASS documentation is easier to read and understand as compared to LESS

Above points clearly prove that the SASS is better CSS pre-processor than the LESS.
