I am creating a SCSS -> HTML plugin and need to first render SCSS -> CSS while keeping the nesting so I can then parse with PostCSS to then create an HTML tree with.
I would like to render SCSS like this
// myMixin.scss
#mixin myMixin {
.myMixin {
padding: 1rem;
background: yellow;
}
}
// main.scss
#import 'myMixin.scss';
$blue: #004AAD;
.button {
.text {
color: $blue;
}
#include myMixin;
}
And the output would look like this:
.button {
.text {
color: #004AAD;
}
.myMixin {
padding: 1rem;
background: yellow;
}
}
Basically, I'd like a way to render everything in SCSS while keeping the original nesting. Is it possible? Thanks.
Nesting is specific to SCSS. Also I don't think #import is best practice, use #use instead.
https://sass-lang.com/documentation/at-rules/use
Here is the thing our client(browsers) only support raw CSS and not SCSS, When you use SCSS it compiles down to raw CSS, And CSS doesn't have inbuilt Nesting feature.
I use scss,
I have a css class, I need some css property to be different, depending of the html element:
<a class="myClass">...</a><input class="myClass"/>
I've try, but it don't work:
.myClass {
&.someOtherClass{...}
&text-area{...}
&input{...}
}
Any idea?
for easy readinf, I need the element to be define INSIDE the class, I can't use something like
input{ &.myClass{...}}
text-area{ &.myClass{...}}
With the #at-root directive you can write your SCSS code in a nested fashion but the resulting CSS will not be nested.
.myClass {
#at-root input#{&} { color: red; }
}
will result in
input.myClass {
color: red;
}
But honestly I don't find this better readable than just doing it KISS:
.myClass { ... }
input.myClass { ... }
I'm new to tailwindcss, and i want to use both sassy css and tailwind for my new project. But I'm having trouble with the nesting specially when i used "#apply".
section {
#apply .p-4;
ul {
li {
#apply .ml-8 .text-red-600;
li:last-child {
#apply .text-gray-300;
}
}
}
}
the red color apply to all li but the last-child (gray color) is not working. I'm not sure if it's possible
Right now we cant combine the SCSS and tailwind file. But we can achieve this by doing like this, give a class name to ul tag mylist
section {
#apply .p-4;
}
.mylist li {
#apply .ml-8 .text-red-600;
}
.mylist li:last-child {
#apply .text-gray-300;
}
You can use Sass and Tailwind together, though there are a few things to watch out for as detailed in the docs.
Though, as also noted in the docs it is recommended that you use PostCSS exclusively as your pre-processor. You can use nesting, variables and much, much more with PostCSS, there's really nothing that you can do with Sass that you cannot do with PostCSS.
I switched my build process from using Sass to PostCSS exclusively, more than 3 years ago, and I've not found anything missing. Indeed I can do so much more, I've never looked back.
Selector you're trying to build here will be compiled to something like:
section ul li li:last-child {...}
I think what you're trying to achieve here is this:
section {
#apply .p-4;
ul {
li {
#apply .ml-8 .text-red-600;
}
li:last-child {
#apply .text-gray-300;
}
}
}
Sure they can!
Nothing's wrong with them, there are couple of very small drawbacks but nothing special.
If your case, you have a tiny mistake in your code
section {
#apply p-4;
ul {
li {
#apply ml-8 text-red-600;
&:last-child {
#apply text-gray-300;
}
}
}
}
Searched but can't find an answer..
I have an element which gets generated (by an external platform) with the following classes: p-button and button.
Now the SCSS is like this:
.p-button {
&.button {
margin: 10px;
}
}
But I want to refactor using mixin includes (this is a big project so there is no other way of making this code better except using mixins). The mixin takes the given selector and applies a . to it. I can't change the mixin, as it is used by many other teams, so I can't pass the ampersand together with the selector. I tried this:
.p-button {
& {
#include button-appearance("button") {
margin: 10px;
}
}
}
But that doesn't work (puts a space between it). You can't do this:
.p-button {
&#include button-appearance("button") {
margin: 10px;
}
}
Anyone have a clue?
EDIT: Here is the mixin
#mixin button-appearance(
$appearance-class,
$show,
$background-color,
$background-image,
$background-position) {
$sel: $button-selector;
#if $appearance-class {
$sel: $sel + '.' + $appearance-class;
}
#{$sel} {
#include normalized-background-image($background-image);
#include show($show);
background-color: $background-color;
background-position: $background-position;
}
#content;
}
EDIT 2: Here is the $button-selector (I can not edit this in the platform, but maybe overwrite it in my own project?)
$button-class: 'p-button';
$button-selector: '.#{$button-class}';
Everyone, finally found the solution. I just removed the &.button from the .p-button mixin include and now it works:
#include button-appearance ("button") { *styles* }
#include button-appearance () { *styles* }
Edited the answer after the original question was edited adding the used and un modifiable mixin
The original mixin does not append the ‘#content’ passed to the mixin to the generated selector. So if you cannot modify the original mixin, the only way is to add your properties outside the mixin. According to the mixin the selector will match a predefined ‘$button-selector’ variable, so it won’t use your class.
So, if you want to use the same class defined in ‘$button-class’, try the following:
#{$button-selector}.button {
margin: 10px;
}
Will output:
.p-button.button {
margin: 10px;
}
I'm new to Sass so I need help with the creation of a mixing for my input fields.
However, if anyone knows of an already made mixin for this or if Compass has one that accomplishes this, please let me (us) know.
I currently have the following CSS rules in my .scss file:
input[type="text"],
input[type="password"],
input[type="email"],
input[type="search"],
input[type="url"],
textarea,
select { ... }
input[type="text"]:hover,
input[type="text"]:focus,
input[type="password"]:hover,
input[type="password"]:focus,
input[type="email"]:hover,
input[type="email"]:focus,
input[type="search"]:hover,
input[type="search"]:focus,
input[type="url"]:hover,
input[type="url"]:focus,
textarea:hover,
textarea:focus,
select:hover,
select:focus { ... }
Now, as we know HTML5 provides a nice new set of input types, but right now I don't need to add input types like date, month or week, that's why I don't have them listed "yet".
So in the case I need to add them in the future, I'll update that list you see above.
However, my problem is that I feel I'm repeating myself all over here, plus, the work of selecting items, copying, pasting and editing every time for every new input type I add to the list is just plain dumb and I almost sure Sass' mixins can be of help with this. The problem is that creating a mixin for this is honestly very confusing to me.
I've looked around here and the web for something similar but haven't been able to find anything.
Any help with this is greatly appreciated.
Ok, I eventually found the Sass mixing library Bourbon.
They have an 'add-on' for HTML5 input types (here's a link to the .scss file they created), but it doesn't have the :hover or :focus pseudo elements. So I added them.
I honestly don't know if what I did is the best way to write this mixin, but the thing works marvelously:
//************************************************************************//
// Generate a variable ($all-text-inputs) with a list of all html5
// input types that have a text-based input, excluding textarea.
// http://diveintohtml5.org/forms.html
//************************************************************************//
$inputs-list: 'input[type="email"]',
'input[type="number"]',
'input[type="password"]',
'input[type="search"]',
'input[type="tel"]',
'input[type="text"]',
'input[type="url"]',
// Webkit & Gecko may change the display of these in the future
'input[type="color"]',
'input[type="date"]',
'input[type="datetime"]',
'input[type="datetime-local"]',
'input[type="month"]',
'input[type="time"]',
'input[type="week"]';
$unquoted-inputs-list: ();
#each $input-type in $inputs-list {
$unquoted-inputs-list: append($unquoted-inputs-list, unquote($input-type), comma);
}
$all-text-inputs: $unquoted-inputs-list;
// You must use interpolation on the variable:
// #{$all-text-inputs}
//************************************************************************//
// #{$all-text-inputs}, textarea {
// border: 1px solid red;
// }
// :hover and :focus pseudo elements

$inputs-list-hf:'input[type="email"]:hover',
'input[type="number"]:hover',
'input[type="password"]:hover',
'input[type="search"]:hover',
'input[type="tel"]:hover',
'input[type="text"]:hover',
'input[type="url"]:hover',
'input[type="color"]:hover',
'input[type="date"]:hover',
'input[type="datetime"]:hover',
'input[type="datetime-local"]:hover',
'input[type="month"]:hover',
'input[type="time"]:hover',
'input[type="week"]:hover',
'input[type="email"]:focus',
'input[type="number"]:focus',
'input[type="password"]:focus',
'input[type="search"]:focus',
'input[type="tel"]:focus',
'input[type="text"]:focus',
'input[type="url"]:focus',
'input[type="color"]:focus',
'input[type="date"]:focus',
'input[type="datetime"]:focus',
'input[type="datetime-local"]:focus',
'input[type="month"]:focus',
'input[type="time"]:focus',
'input[type="week"]:focus';
$unquoted-inputs-list-hf: ();
#each $input-type-hf in $inputs-list-hf {
$unquoted-inputs-list-hf: append($unquoted-inputs-list-hf, unquote($input-type-hf), comma);
}
$all-text-inputs-hf: $unquoted-inputs-list-hf;
// You must use interpolation on the variable:
// #{$all-text-inputs-hf}
//************************************************************************//
// #{$all-text-inputs-hf}, textarea {
// border: 1px solid red;
// }
As you can see I copied and pasted the original mixing and added the prefix -hf and of course the :hover and :focus to the new rules.
And in my .scss file I added this #import:
#import "html5-input-types"; (no need for the underline _ or file extension .scss)
And in the 'Forms' section of my .scss file I added these rules:
/*Normal state*/
#{$all-text-inputs},
textarea,
select { ... }
/*:hover and :focus states*/
#{$all-text-inputs-hf},
textarea:hover,
textarea:focus,
select:hover,
select:focus { ... }
I know I have textarea and select outside the mixin file (html5-input-types.scss), not sure yet if I'm including them in it or not, gotta think about it.
Anyway, this worked for me pretty well and although I will still need to update the html5-input-types.scss if anything changes in the future, at least I'm handling these input fields way more efficiently than before.
Hopefully what I did here helps someone else.
And if any of you has a suggestion to improve the mixin, by all means let me (us) know.
Thanks.
In case anyone comes across this for the same reason I did. Why not let SASS do the work?
