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?
Is it possible to combine multiple sass functions?
For example i'd like to use saturate and darken
is this possible?
eg
color: darken(red, 5%)
color: desaturate(red, 15%)
Yes of course! Just use the following.
color: desaturate(darken(red, 5%), 15%);
Realized I could just assign the result of the first color as the argument in the second:
$darkend: darken(red, 5%)
$desaturated: desaturate($darkend, 15%)
color: $desaturated
i have written the following two mixins:
#mixin textcolor($hexvaltxt, $opacitytxt: 1.0){
color: $hexvaltxt;
color: rgba($hexvaltxt, $opacitytxt);
}
#mixin boxcolor($hexvalbox, $opacitybox: 1.0){
background-color: $hexvalbox;
background-color: rgba($hexvalbox, $opacitybox);
}
basically i enter a hexvalue and in return i get a fallback color as hexvalue as well as a rgba value. basically based on what i have read the rgba function of compass should convert the hexvalue and the opacity into a rgba value. but when i call my mixin:
.maintitle {
#include textcolor($sectionhead);
}
$sectionhead has #3f3e3e as value. then i get the following output:
.maintitle {
color: #3f3e3e;
color: #3f3e3e; }
instead of showing one hex and one rgba value i get only the same hex value twice. :/ isnt the conversion provided anymore or am i doing something completely wrong? as a side note i am running the latest compass (0.12.2) and sass (3.2.1). best regards ralf
1.0 is completely opaque, so I am guessing Sass just leaves it as is since that would be optimal for backwards compatibility. If I change the second argument to .8, I get this output:
.maintitle {
color: #3f3e3e;
color: rgba(63, 62, 62, 0.8);
}
