I have a button class .btn and want to select only when it is with a link. What to add to a so I will get a.btn using SCSS and my code bellow?
SCSS:
.btn {
background: red;
a {
background: blue;
}
}
I want to get this in css:
.btn {
background: red;
}
a.btn {
background: blue;
}
Logical will be to do this a&. But it gives an error. a & and & a is giving a different result.
I know that this can be done with #at-root a#{&} but it is too ugly =) Is there a pretty way?
.btn {
background: red;
#at-root a#{&} {
background: blue;
}
}
This should work:
a {
&.btn {
background: blue;
}
}
.btn {
background: red;
}
You can't write that in a single block. In case if that's what you are trying to do.
Since .btn& is not a valid scss, it seems that #at-root a#{&} is your only option.

I've got this Scss:
.top {
background-color: red;
&--checked {
background-color: yellow;
}
&--completed {
background-color: green;
}
}
Which compiles correctly to this:
.top {
background-color: red;
}
.top--checked {
background-color: yellow;
}
.top--completed {
background-color: green;
}
This is probably simple, but I'm trying to add an additional style for elements using both "top--checked" and "top--completed", but nested within top.
Something like this (in CSS):
.top--checked.top--completed {
background-color: blue;
}
I'm just not sure on how to achieve this, as chaining ampersands doesn't seem to produce the desired effect.
I think the best you can do would be something like this:
&--checked#{&}--completed {
background: blue;
}
When I do a yarn build of the scss below I can only see the .select-list__item:hover in the compiled css, I am not seeing anything else from the class such as .select-list__item--selected I am not sure what the issue here is.
%select-list__item {
&:hover {
background: red;
}
&--selected,
&--selected:nth-child(2n),
&--selected:hover {
background: #00FF00;
}}
.select-list__item {
#extend %select-list__item;}
I believe it is to do with how placeholders (ie: %chosen-name) are meant to be used.
Although this is not explicitly pointed out in the documentation they are meant to be small bits that are reusable.
At my company, we use one for our generic button styles (margin, padding, font) and we extend that into all of our buttons (primary, secondary, tertiary).
A potential solution for your use case:
%select-list__item {
&:hover {
background: red;
}
&:focus{
background: blue;
}
}
.select-list__item {
#extend %select-list__item;
&--selected,
&--selected:nth-child(2n),
&--selected:hover {
background: #00FF00;
}
}
Or here's another - bit of an OTT solution for the example but you get the idea:
%select-list__item {
&:hover {
background: red;
}
&:focus{
background: blue;
}
}
%selected-list__item {
background: #00FF00;
&:nth-child(2n),
&:hover {
background: #00FF00;
}
}
.select-list__item {
#extend %select-list__item;
&--selected {
#extend %selected-list__item
}
}
Given the following HTML / SASS code:
<div class="a">hello</div>
%color {
color: blue;
}
.a {
color: red;
}
.a.a {
#extend %color;
}
I was expecting the resulting color to be blue (due to the more specific .a.a selector1) with output something like this:
.a.a {
color: blue;
}
.a {
color: red;
}
But actually, the resulting color is red, with SASS output:
.a {
color: blue;
}
.a {
color: red;
}
I find this quite counter-intuitive!
Why does SASS refactor my .a.a selector to .a?
Just in case you don't believe me, here's a codepen demo (click view compiled css to see the CSS output)
NOTE:
This 'refactoring' of the selector only occurs to the declarations within the extend.
So in the following SASS:
%color {
color: blue;
}
.a.a {
#extend %color;
position: relative;
}
The output is:
.a {
color: blue;
}
.a.a {
position: relative;
}
(Codepen demo)
1See the spec:
Note: Repeated occurrences of the same simple selector are allowed and
do increase specificity.
By the looks of it, the result depends on the parsing engine. If you use DartSass v1.6.2 (default on sassmeister.com), it outputs your expected result:
.a.a {
color: blue;
}
.a {
color: red;
}
Check on sassmeister.com (you can also switch parsing engines there).
LibSass v3.5.2 creates the result you complained about:
.a {
color: blue;
}
.a {
color: red;
}
I've a LESS code like:
.block__element {
background: red;
&--modifier {
background: yellow;
}
}
I want more specificity to .block__element--modifier such as:
.block__element.block__element--modifier {
background: yellow:
}
So that it can overrides some other styles.
I can achieve it by:
.block__element {
background: red;
&--modifier.block__element {
background: yellow;
}
}
I want to know is there any easy way?
You could achieve it in a more fancy way using variable interpolation, so that every time you need to increase the specificity of a class/modifier you can use it.
It seems weird at first, but when you'll get used to it you will love it and your code will look much more clean and easy to read.
Check the official documentation
.block__element {
#this: block__element;
background: red;
&.#{this}--modifier-primary {
background: yellow;
}
&.#{this}--modifier-secondary {
background: green;
}
&.#{this}--modifier-tertiary {
background: green;
}
}
.block__element {
background: red;
&&--modifier {
background: yellow;
}
}

sorry but it's confusing to me, somebody knows how it's possible or it's not possible..
#divp {
background-color: lightgrey;
.odiv {
background-color: yellow;
.pp { background-color: black; }
a { color:red; }
}
.pp { background-color: lightgreen; }
a { color:blue; }
}
#divw {
background-color: lightblue;
.odiv {
background-color: blue;
.pp { background-color: white; }
a { color:yellow; }
}
.pp { background-color: green; }
a { color:lightblue; }
}
i want create divs with internal css rules and i dont want to write all the time the same..... like
#diw .odiv .pp { background-color: white }
#diw .odiv .a { color: white }
#diw .odiv .other { color: blue }
is it possible?
Nesting selectors is not possible, but you might want to checkout CSS preprocessors, which will let you do this. http://lesscss.org/ for example.
It is not possible in standard CSS. But it is possible in Sass (and other CSS Preprocessors): http://sass-lang.com/guide#3
It works exactly as you posted in your question:
.div1{
background-color: red;
p{ font-size: 18px; }
}
Will output this:
.div1{ background-color: red }
.div1 p{ font-size: 18px; }
