Question
From what I've been reading, Sass is a language that makes CSS more powerful with variable and math support.
What's the difference with SCSS? Is it supposed to be the same language? Similar? Different?
Solution
Sass is a CSS pre-processor with syntax advancements. Style sheets in the advanced syntax are processed by the program, and turned into regular CSS style sheets. However, they do not extend the CSS standard itself.
CSS variables are supported and can be utilized but not as well as pre-processor variables.
For the difference between SCSS and Sass, this text on the Sass documentation page should answer the question:
The SCSS syntax uses the file extension
.scss. With a few small exceptions, it’s a superset of CSS, which means essentially all valid CSS is valid SCSS as well. Because of its similarity to CSS, it’s the easiest syntax to get used to and the most popular.
The indented syntax was Sass’s original syntax, and so it uses the file extension
.sass. Because of this extension, it’s sometimes just called “Sass”. The indented syntax supports all the same features as SCSS, but it uses indentation instead of curly braces and semicolons to describe the format of the document.
However, all this works only with the Sass pre-compiler which in the end creates CSS. It is not an extension to the CSS standard itself.
Solution
I'm one of the developers who helped create Sass.
The difference is syntax. Underneath the textual exterior they are identical. This is why sass and scss files can import each other. Actually, Sass has four syntax parsers: scss, sass, CSS, and less. All of these convert a different syntax into an Abstract Syntax Tree which is further processed into CSS output or even onto one of the other formats via the sass-convert tool.
Use the syntax you like the best, both are fully supported and you can change between them later if you change your mind.
Solution
The Sass .sass file is visually different from .scss file, e.g.
$color: red
=my-border($color)
border: 1px solid $color
body
background: $color
+my-border(green)
$color: red;
@mixin my-border($color) {
border: 1px solid $color;
}
body {
background: $color;
@include my-border(green);
}
Any valid CSS document can be converted to Sassy CSS (SCSS) simply by changing the extension from .css to .scss.
Solution
Sass (Syntactically Awesome StyleSheets) have two syntaxes:
So they are both part of Sass preprocessor with two different possible syntaxes.
The most important difference between SCSS and original Sass:
SCSS:
Syntax is similar to CSS (so much that every regular valid CSS3 is also valid SCSS, but the relationship in the other direction obviously does not happen)
Uses braces {}
Uses semi-colons ;
Assignment sign is :
To create a mixin it uses the @mixin directive
To use mixin it precedes it with the @include directive
Files have the .scss extension.
Original Sass:
= instead of := sign+ signSome prefer Sass, the original syntax - while others prefer SCSS. Either way, but it is worth noting that Sass’s indented syntax has not been and will never be deprecated (web archive).
Conversions with sass-convert:
# Convert Sass to SCSS
$ sass-convert style.sass style.scss
# Convert SCSS to Sass
$ sass-convert style.scss style.sass
Solution
Its syntax is different, and that's the main pro (or con, depending on your perspective).
I'll try not to repeat much of what others said, you can easily google that but instead, I'd like to say a couple of things from my experience using both, sometimes even in the same project.
SASS pro
.sass is much 'easier' and readable than in .scss (subjective).SASS cons
body color: red like you can in .scss body {color: red}.scss files (alongside with .sass files) in your project or to convert them to .sass.Other than this - they do the same job.
Now, what I like to do is to write mixins and variables in .sass and code that will actually compile to CSS in .scss if possible (ie Visual studio doesn't have support for .sass but whenever I work on Rails projects I usually combine two of them, not in one file ofc).
Lately, I'm considering giving Stylus a chance (for a full-time CSS preprocessor) because it allows you to combine two syntaxes in one file (among some other features). That may not be a good direction for a team to take but when you are maintaining it alone - it's ok. The stylus is actually most flexible when syntax is in question.
And finaly mixin for .scss vs .sass syntax comparison:
// SCSS
@mixin cover {
$color: red;
@for $i from 1 through 5 {
&.bg-cover#{$i} { background-color: adjust-hue($color, 15deg * $i) }
}
}
.wrapper { @include cover }
// SASS
=cover
$color: red
@for $i from 1 through 5
&.bg-cover#{$i}
background-color: adjust-hue($color, 15deg * $i)
.wrapper
+cover
Solution
From the homepage of the language
Sass has two syntaxes. The new main syntax (as of Sass 3) is known as “SCSS” (for “Sassy CSS”), and is a superset of CSS3’s syntax. This means that every valid CSS3 stylesheet is valid SCSS as well. SCSS files use the extension .scss.
The second, older syntax is known as the indented syntax (or just “Sass”). Inspired by Haml’s terseness, it’s intended for people who prefer conciseness over similarity to CSS. Instead of brackets and semicolons, it uses the indentation of lines to specify blocks. Although no longer the primary syntax, the indented syntax will continue to be supported. Files in the indented syntax use the extension .sass.
SASS is an interpreted language that spits out CSS. The structure of Sass looks like CSS (remotely), but it seems to me that the description is a bit misleading; it's not a replacement for CSS, or an extension. It's an interpreter which spits out CSS in the end, so Sass still has the limitations of normal CSS, but it masks them with simple code.
Solution
SASS stands for Syntactically Awesome StyleSheets. It is an extension of CSS that adds power and elegance to the basic language. SASS is newly named as SCSS with some chages, but the old one SASS is also there. Before you use SCSS or SASS please see the below difference.
An example of some SCSS and SASS syntax:
SCSS
$font-stack: Helvetica, sans-serif;
$primary-color: #333;
body {
font: 100% $font-stack;
color: $primary-color;
}
//Mixins
@mixin transform($property) {
-webkit-transform: $property;
-ms-transform: $property;
transform: $property;
}
.box { @include transform(rotate(30deg)); }
SASS
$font-stack: Helvetica, sans-serif
$primary-color: #333
body
font: 100% $font-stack
color: $primary-color
//Mixins
=transform($property)
-webkit-transform: $property
-ms-transform: $property
transform: $property
.box
+transform(rotate(30deg))
Output CSS after Compilation(Same for Both)
body {
font: 100% Helvetica, sans-serif;
color: #333;
}
//Mixins
.box {
-webkit-transform: rotate(30deg);
-ms-transform: rotate(30deg);
transform: rotate(30deg);
}
For more guide you can see the official website.
Solution
The basic difference is the syntax. While SASS has a loose syntax with white space and no semicolons, the SCSS resembles more to CSS.
Solution
Sass was the first one, and the syntax is a bit different. For example, including a mixin:
Sass: +mixinname()
Scss: @include mixinname()
Sass ignores curly brackets and semicolons and lay on nesting, which I found more useful.
Solution
Difference between SASS and SCSS article explains the difference in details. Don’t be confused by the SASS and SCSS options, although I also was initially, .scss is Sassy CSS and is the next generation of .sass.
If that didn’t make sense you can see the difference in code below.
/* SCSS */
$blue: #3bbfce;
$margin: 16px;
.content-navigation {
border-color: $blue;
color: darken($blue, 9%);
}
.border {
padding: $margin / 2; margin: $margin / 2; border-color: $blue;
}
In the code above we use ; to separate the declarations. I’ve even added all the declarations for .border onto a single line to illustrate this point further. In contrast, the SASS code below must be on different lines with indentation and there is no use of the ;.
/* SASS */
$blue: #3bbfce
$margin: 16px
.content-navigation
border-color: $blue
color: darken($blue, 9%)
.border
padding: $margin / 2
margin: $margin / 2
border-color: $blue
You can see from the CSS below that the SCSS style is a lot more similar to regular CSS than the older SASS approach.
/* CSS */
.content-navigation {
border-color: #3bbfce;
color: #2b9eab;
}
.border {
padding: 8px;
margin: 8px;
border-color: #3bbfce;
}
I think most of the time these days if someone mentions that they are working with Sass they are referring to authoring in .scss rather than the traditional .sass way.
Solution
Original sass is ruby syntax-like, similar to ruby, jade etc...
In those syntaxes, we don't use {}, instead we go with white spaces, also no usage of ;...
In scss syntaxes are more like CSS, but with getting more options like: nesting, declaring, etc, similar to less and other pre-processing CSS ...
They basically do the same thing, but I put couple of lines of each to see the syntax difference, look at the {}, ;, and spaces:
SASS:
$width: 100px
$color: green
div
width: $width
background-color: $color
SCSS:
$width: 100px;
$color: green;
div {
width: $width;
background-color: $color;
}
Solution
The compact answer:
SCSS refers to the main syntax supported by the Sass CSS pre-processor.
.scss represent the standard syntax supported by Sass. SCSS is a superset of CSS..sass represent the "older" syntax supported by Sass originating in the Ruby world.Solution
SASS is Syntactically Awesome Style Sheets and is an extension of CSS which provides the features of nested rules, inheritance, Mixins whereas SCSS is Sassy Cascaded Style Sheets which is similar to that of CSS and fills the gaps and incompatibilities between CSS and SASS. It was licensed under the MIT license. This article has more about the differences:https://www.educba.com/sass-vs-scss/
Solution
SCSS is SASS.
You can't say they are different.
But .scss and .sass files are different SASS syntaxes.
Sass has two syntaxes.
The SCSS syntax (.scss) is used most commonly. It's a superset of CSS, which means all valid CSS is also valid SCSS.
The indented syntax (.sass) is more unusual: it uses indentation rather than curly braces to nest statements, and newlines instead of semicolons to separate them. (Similar to python syntax)
Solution
SCSS is the new syntax for Sass. In Extension wise, .sass for the SASS while .scss for the SCSS. Here SCSS has more logical and complex approach for coding than SASS. Therefore, for a newbie to software field the better choice is SCSS.
Solution
Found myself wondering the same thing, and stumbled upon a straight-forward explanation in Harvard's CS50:
A language called Sass ... (is) essentially an extension to CSS ... it adds additional features to CSS ... just to make it a little bit more powerful for us to use.
One of the key features of Sass is the ability to use variables
The Sass extension is .scss (as opposed to .css for a regular CSS file).
So, when we ask "what is the difference between scss and sass?" - the answer could simply be that .scss is simply the file extension used when wishing to use Sass instead of regular CSS.
