I have created a blank project in angular 4 and I am trying to design it but the sass isn't working when ever I add sass and run project I am getting this error
body{
h1{
color : red;
}
}
^
Invalid CSS after "body{": expected "}", was "{"
in C:projectname/src\styles.sass (line 1, column 6)
My index.html code is
<body>
<h1>Here</h1>
</body>
Any help would be appreciated
Based on your error message (C:projectname/src\styles.sass) It seems you're using the .sass extension for a SCSS file. Change your file name to styles.scss.
Sass and SCSS use two different and incompatible syntaxes.
There are two syntaxes available for Sass. The first, known as SCSS
(Sassy CSS) and used throughout this reference, is an extension of the
syntax of CSS. This means that every valid CSS stylesheet is a valid
SCSS file with the same meaning. This syntax is enhanced with the Sass
features described below. Files using this syntax have the .scss
extension.
The second and older syntax, known as the indented syntax (or
sometimes just “Sass”), provides a more concise way of writing CSS. It
uses indentation rather than brackets to indicate nesting of
selectors, and newlines rather than semicolons to separate properties.
Files using this syntax have the .sass extension.

I'd like to put a shared constant in a single .sass file and then import this in other .sass files but I'm getting Invalid CSS errors. currently, my code is structured as:
// src/react/stylesheets/_constants.sass
$uiAccent: black
and
// src/react/stylesheets/myComponent.sass
#use "constants"
//...
.item
border-bottom: 1px solid
border-color: constants.$uiAccent
I modeled this based on the official sass guide for #use and as best I can tell, my structure is identical to theirs.
When I run sass --watch src/react/stylesheets/:src/react/css/ to convert my sass files to css ones, I get error src/react/stylesheets/myComponent.sass (Line 12: Invalid CSS after "constants": expected expression (e.g. 1px, bold), was ".$uiAccent")
I've tried moving the variable into the file where it was used (so I just removed the #use line and copied in the variable assignment), and it all works fine, so I don't think it's an issue with the sass to css conversion, and I've made sure all my files are .sass and not .scss because I've seen someone have a similar problem with .scss files.
I found this github issue which looks similar, especially the related one about node-sass but these were both from 2015 so I have a hard time believing that such a common feature has been broken for 5 years.
Update: I realized that I misunderstood the page on #use and that it's only supported by Dart Sass right now, not LibSass, so #import is not discouraged in this case.
Working on calc css function its work properly in browser and less file. But my text-editor shows error within css file.
This is the css file (I use VS code)
You don't define $gutter-horizontal anywhere, so its value cannot be used in the calculation. You need to initialise this variable with something like:
$gutter-horizontal: '12px';
Note that calc() will not work correctly with Sass, and to accommodate for this, you'll need to interpolate the variable:
width: calc((100% - #{$gutter-horizontal}) / 2)
Also, the vast majority of your CSS won't compile as you have pre-processed SASS in a .css file. You can convert it to regular CSS using an online tool such as SassMeister (or simply change the file extension to .scss, assuming your project can compile SASS).
your file is a css, your syntax it's for some preprocessor like sass or less
Just decided to learn SASS, pretty easy stuff except a very basic file won't compile.
It's literally this basic:
$test: #ffffff;
Command:
sass test.sass
Error Message:
error: expected "
".
$test:#ffffff;
^
test.sass 1:14 root stylesheet
I've no idea what it means by expected " - expected where??
please change extension test.sass to test.scss. and you good to go. 100% :)
As per sass-lang.com.
There are two syntaxes available for Sass. The first, known as SCSS
(Sassy CSS) and used throughout this reference, is an extension of the
syntax of CSS. This means that every valid CSS stylesheet is a valid
SCSS file with the same meaning. In addition, SCSS understands most
CSS hacks and vendor-specific syntax, such as IE's old filter syntax.
This syntax is enhanced with the Sass features described below. Files
using this syntax have the .scss extension.
The second and older syntax, known as the indented syntax (or
sometimes just "Sass"), provides a more concise way of writing CSS. It
uses indentation rather than brackets to indicate nesting of
selectors, and newlines rather than semicolons to separate properties.
Some people find this to be easier to read and quicker to write than
SCSS. The indented syntax has all the same features, although some of
them have slightly different syntax; this is described in the indented
syntax reference. Files using this syntax have the .sass extension.
I've started Vim (v8) and have proper syntax highlighters in place for css3. I am using postcss plugin called precss to provide for "SASS" like syntax in my code.
However, when I used a nested selector with "&:last-child" or &:first-child, the syntax throws an error. It doesn't break the code or anything, but that "red" error is so distracting for me. Check the screen shot below.
Anyone can figure out how to make this error go?? I use a plugin called vim-css3-syntax and it includes scss syntax highlighting.
Edit: Got it fixed by downloading https://github.com/cakebaker/scss-syntax.vim and then adding au BufRead,BufNewFile *.css set filetype=scss.css
Thanks in advance.
The fact that you are using SCSS syntax (nested blocks, &, etc.) in CSS makes your CSS invalid.
If you want to avoid syntax errors you have two paths:
stop using SCSS syntax in your CSS files,
make sure your file is recognized as what it is: SCSS.
I would consider the first path to be the most sensible. After all who writes JavaScript in a *.rb file or SCSS in a *.css file? But if you choose the second you can simply do:
setf scss

Suppose we have this code:
body {
background-color: white;
}
It's both valid CSS and valid SCSS because SCSS is a superset of CSS. Any valid CSS is automatically valid SCSS. Vim will happily display it without any error, no matter what file extension (*.css, *.scss) and filetype (css, scss).
Now, suppose we have this code:
body {
h1 {
background-color: $brand-1;
}
}
It's valid SCSS but not valid CSS. If you write that code in a *.css file with the css filetype, you get errors because it's not CSS. If you write that code in a *.scss file with the scss filetype you don't get errors because it's valid SCSS.
I have just started using sass and still learning. I am using this command to generate css from sass:
sass --watch custom.scss:custom.css
It seems to remove empty classes and IDs. Is it possible to include them on the resulted css?
SASS never compiles empty classes, as a workaround you can add a CSS comment inside the class with no rules, so it will be compiled.
.empty {
/*I'm still empty*/
}
