I would like to write such a mixin so that you can conditionally pass an array consisting of a property and its value. I will give an example to make it clearer, it is obviously incorrect due to poor knowledge of sass. Is it possible to implement with the tools that sass provides?
#mixin myMedia($args) {
$sizes: (
xxl: 1920px,
xl: 1440px
);
#for $i from 1 through $args {
#media(max-width: $sizes[$i])
$args[$i] #content
}
}
#include myMedia(
{font-size: 16p; line-height: 16px;},
{font-size: 14p; line-height: 14px;}
)
I tried for , each , functions , but didn't come up with anything like what I described above

I have two separate SASS files among many, on a ReactJS repository, such as _main.sass and _partials.sass. They are combined using #use on a separate file named index.css.
The SASS package as a dependency is just sass via npm.
_main.sass and all of its variables can be accessed by _partials.sass, thanks to #use "./main" as *.
I have the following code on _main.sass which detects OS preference for dark mode:
#media (prefers-color-scheme: light)
body
background-color: $white
color: $black
#media (prefers-color-scheme: dark)
body
background-color: $dark
color: $light
All of these color variables are defined and they're working well.
But the problem is that I need to use complement() function on the background-color which is currently active, in _partials.sass.
The main issue seems to me that when I assign a variable e.g. $accent on both ends of the media queries, the variable does not get picked up by the remote file. I could not wrap my head around to do it in such way, since I'm only a beginner at coding SASS.
Unfortunately, I need the plain CSS #media query implementations for automatically detecting the preference. But any suggestion is appreciated in case it is impossible to keep it like that and achieve what I wanted.
Thank you!
I've found the solution myself.
So, I was trying to make a light/dark theme compliant SASS implementation.
What complement function does is that it rotates the color in the input for 180deg on the RGB hue. I needed this to get corresponding inverted-like colors for each color, for better dark-mode contrast. The difference between invert and complement are listed here.
But, I realized that I did not need that. Here is the code for my theme implementation using SASS.
// rainbow
$blue: #00a4ef
$yellow: #f4b400
$red: #db4437
$green: #61b500
$purple: #6e14ef
$pink: #ff0090
$carmine: #c6004b
// monochroma
$white: #fff
$light: #f5f5f5
$lgray: #c2c2c2
$dgray: #6e6e6e
$ldark: #363636
$dark: #232323
$black: #000
$themes: (light: (logo: url("../static/logo-light.svg"), bg: $white, card-bg: $light, text: $black, link: $red, hover: $pink, active: $carmine, border: $lgray, button: $yellow), dark: (logo: url("../static/logo-dark.svg"), bg: $dark, card-bg: $ldark, text: $light, link: $red, hover: $pink, active: $carmine, border: $dgray, button: $purple))
#mixin themeProperty($theme, $property, $color, $additionalProperties)
#if $additionalProperties
#{$property}: unquote(map-get($theme, $color) + " " + $additionalProperties)
#else
#{$property}: unquote(map-get($theme, $color))
#mixin theme($property, $color, $additionalProperties: "")
$light: map-get($themes, light)
$dark: map-get($themes, dark)
#media (prefers-color-scheme: light)
#include themeProperty($light, $property, $color, $additionalProperties)
#media (prefers-color-scheme: dark)
#include themeProperty($dark, $property, $color, $additionalProperties)
There is a color map named "themes" which lists each color for light and dark themes for different use cases.
Furthermore, the mixins match the exact color for exact usage for the desired theme mode, whichever is being used by the client-side (browser or OS), thanks to #media queries.
For example, if you'd like to color a background-color using the button preset on the theme mapping, the usage is as follows:
#include theme("background-color", button)
I've been introduced to the gridlover tool. It provides SASS variables like:
$scale0: (
fontSize: 1em,
line: 1.5em,
autoLineCount: 1,
autoLineHeight: 1.5em
);
But I can't figure out what all the values correspond to.
I understand that I can use each one using map-get. fontSize is obviously used to set font-size and line looks like line-height.
.some-class {
font-size: map-get($scale0, fontSize);
line-height: map-get($scale0, line);
}
But what are autoLineCount and autoLineHeight? Are these SASS keywords? What am I suppose to do with them?
I can't get a mixin to accept a block:
=my-mixin($some-var)
width: $some-var
#content // Is this correct?
+my-mixin(123px)
height: 100px
This results in a "mixin doesn't accept a content block" error. I'm using the current version of Sass. Thanks for help.
syntax is ok with version 3.2 of SASS, double check that
For me the problem was with SASS indentation.
You can't nest another block within a mixin like this:
.button-cta
+button (transparent, tomato)
&:hover
background-color: tomato
color: #fff
instead:
.button-cta
+button (transparent, tomato)
&:hover
background-color: tomato
color: #fff
hover state must not be nested
I was getting this error too. Turned out that somewhere else in my scss I was using #mixin mobile-only instead of #include mobile-only - aka, I was accidentally redefining the mixin later in the code.
I'm attempting to re-learn 960gs using sass syntax. I am confused on the difference between "+" and "=" sass syntax. For example:
.wrapper
+grid-container
and
.wrapper
#include grid_container
would produce the same results in my compiled css file
.wrapper {
margin-left: auto;
margin-right: auto;
width: 960px;
}
So what is the difference between using "+" and "#include"?
No difference at all. Quoting Sass documentation:
Sass supports shorthands for the #mixin and #include directives. Instead of writing #mixin, you can use the character =; instead of writing #include, you can use the character +.
This question already has answers here:
Adding a unit to a number in Sass
(2 answers)
Closed 7 years ago.
I am quiet new to Sass... I want to create some css with percentage values like:
width : 13%;
The value is the result of a sass number operation. Writing this
width : $main-width + "%"
scss code generates this:
width : "13%";
css, what is actually not working because it should be:
width : 13%;
writing
width : $main-width %;
results in
width : 13 "%"
what also leads to a non working css-rule. Is there a way to make Sass print 13% plain, with no quotes?
Think of units in Sass like variables in algebra instead of just concatenating strings.
In algebra:
2x * 3 = 6x
In Sass:
13 * 1% = 13%
Use this approach to do more advanced math.
10px * 3px = 30px*px
But px*px isn't a valid CSS unit so you have to cancel one out by dividing by 1px
30px*px / 1px = 30px
Hope this helps beyond your original question.
unquote("%") does the trick.
You could try #.
I had a similar problem with a mixin and lists
#mixin p($value, $position: a, $unit: $rhythm-unit){
$vallist: ();
#if length($value) > 1 {
#each $sval in $value {
$sval: 0 !default;
$vallist: append($vallist, #{$sval}#{$unit});
}
padding: $vallist;
} #else{
#if $position == t {
padding-top: $value+$unit;
} #else if $position == r {
padding-right: $value+$unit;
} #else if $position == b {
padding-bottom: $value+$unit;
} #else if $position == l {
padding-left: $value+$unit;
} #else {
padding: $value+$unit;
}
}
}
The problem was
append($vallist, $sval+$unit);
It always added quotes around these values e.g. "1rem" "1.25rem" which is not a correct css syntax.
I replaced it with:
append($vallist, #{$sval}#{$unit});
As you can see i use #-sign with {} and + it not necessary any more.
The very interesting here is that this only appear with lists/append as you can see in my outer else.
You could find it at the sass reference page Division and slash
If you want to use variables along with a plain CSS /, you can use #{} to insert them. For example:
p {
$font-size: 12px;
$line-height: 30px;
font: #{$font-size}/#{$line-height};
}
Hope it helps
