How can I style my React component using Sass and CSS modules based on the existence of a GLOBAL parent selector (in this case isOpen)?
Rendered HTML:
<div class="isOpen">
<div class="MyContainer__MyStyle___u9dTa">
My react component
</div>
</div>
My Sass file:
.MyStyle
margin-left: 100px
color: black
// TODO: Override MyStyle if 'isOpen' is on parent, e.g. something like:
.MyStyle
:global(.isOpen) &
margin-left: 0
color: red
The code above gives error: Property "global" must be followed by a ':'
Though it's a little late for me to answer, I think I found the answer and I'll post it for those who may encounter this problem in the future.
The problem is in Sass you have to escape the :global keyword with \:global in order to make CSS module works as you expected.
The discussion can be found at https://github.com/webpack-contrib/sass-loader/issues/448.
It looks like you have a few issues here.
"MyContainer__MyStyle___u9dTa" is one big class name. You cannot reference one part by using the period syntax. however you can reference a partial class like this..
*[class=*"MyStyle"]{}
It also looks like you are using LESS syntax instead of sass. here is how i would write the code with sass and partial class references
*[class=*"MyStyle"]{
margin-left: 100px;
color: black;
}
// TODO: Override MyStyle if 'isOpen' is on parent, e.g. something like:
.isOpen{
*[class=*"MyStyle"]{
margin-left: 0
color: red
}
}
good luck. and its worth noting that you can use vanilla CSS within a sass file if that is easier for you. Here are some resources for CSS and SASS

How can I override some default values from primereact e.g. the primary color?
I read that i have to override the values by adding the following code in the proviced override.scss
:root {
--primaryColor: green;
--primaryTextColor: #ffffff;
--panelContentBorder: 1px solid #c8c8c8;
}
Unfortunately, my changes are not applied when working with e.g. a button-class (which is working with the primary color). I also read that the overrides must happen before the actual class is created.
How can I do that? Do I need to run a SCSS-command?
In my remember, You can override variables in overrides/_layout_variables.scss or overrides/_theme_variables.scss files. Also you may need to upgrade your version to the latest.
You can override variable for some more specific rule
e.g.
:root {
--primaryColor: green;
--primaryTextColor: #ffffff;
--panelContentBorder: 1px solid #c8c8c8;
}
.somePage {
--primaryColor: blue;
// So primaryColor will be blue for all rules in scope of .somePage
}
Well to overwrite SCSS/SASS/LESS variables in general you could do the following (The process does also work with less instead of .scss)
Create a new .scss file
Instead of directly including the frameworks (doesnt matter which one you use) .scss include your OWN created .scss file (step 1)
Import the framework's .scss file in your own, custom .scss file
Compile your own .scss file using e.g. node-sass
Example of your own .scss file
#import "node_modules/path_to_the_libaries_scss_file.scss";
// Overwrite colors like this:
$primary-color: #ff5b00;
I am using Material-UI in my react application. Recently, I updated my packages to the latest version. Now, when I open a dialog in my application, padding-right: 17px; will be added to the body tag.
I also checked the Material-UI site, and this is happening on their website too with dialogs.
Is this a bug with the new version of Material-UI?
How can I remove this padding from the body tag when opening a dialog?
Update: This padding will be added to the body tag with Drawer, Menu, Dialog, and Popover components.
as it was mentioned by #Reins you can use disableScrollLock property. The thing is sometimes this property is nested on components's input so you need to use inputProps in order to set it. Here is an example with Select component:
<Select
className={classes.select}
inputProps={{MenuProps: {disableScrollLock: true}}}
...
/>
Sometimes you may want to dig into MUI codebase in order to figure out how to apply some nested element's properties.
Just give disableScrollLock={ true }.
I think it will solve the issue because I had the same.
I added disableScrollLock prop to my Dialog Component.
It worked.
You can use a mui-fixed class for handling this issue, it's helpful for me.
Here is a link for material UI mui-fixed document :

Hope this will help anyone.
For me the solution was to add
overflow: auto;
to the #root selector:
#root {
... other css that was there before
overflow: auto;
}
I add in my main css file the following snippet of code and I get rid of body margins:
body {
margin: 0;
}
I realized this came from a parent Container. I just added this and it worked for me. Also realized this is adaptive to screen size, so this code is applied to all the sizes from xs and up breakpoints.
sx={{
[theme.breakpoints.up("xs")]: {
padding: 0
},
}}
I want to have a file just to store the colors and some other settings that I am going to use in my css styles. Because I don't want to specify the same color in different files multiple times. How can I achieve that with css modules?
For example:
setting.css
$primary-color: #785372;
$secondary-corlor: #22b390;
Button/styles.css
.button {
background: $primary-color;
display: flex;
}
From your samples that looks like Sass (which can be used in conjunction with CSS modules). If so then just import the partial containing the variables.
#import 'path/to/variables.scss';
If there's no Sass involved then postcss-modules-values is what your looking for:
variables.css
#value primary: #785372;
#value secondary: #22b390;
styles.css
#value primary, secondary from './path/to/variables.css';
.button {
background: primary;
display: flex;
}
EDIT:
Actually there's even more options, still through PostCSS plugins. postcss-simple-vars or postcss-custom-properties, the later having the clear advantage to stay close to the CSS specification.
They all share the same requirement though, importing the configuration file in a way or another.
You can do this with using CSS Custom Properties (here's a tutorial I've found).
In your settings.css file, do (the `:root':
:root {
--primary-color: #785372;
--secondary-corlor: #22b390;
}
Then, you can use those constants in the same, or a different file
.container {
color: var(--primary-color);
}
If you're using them in a different file, be sure to import both stylesheets, for example:
import './Button/styles.css'
import './settings.css'
Also, according to this answer, you can do this in html as well, by linking the two stylesheets:
<link href="settings.css" rel="stylesheet">
<link href="Button/style.css" rel="stylesheet">
Angular 2 has this special selector to reference its own component like:
:host
display: block
height: 100% !important
width: 100%
text-align: center
position: relative
But Intellij do not present me any way to supress this warnign. It confuses me when I am looking for actual errors on the Project folders
There is nothing wrong with Intellij. It is using Sass default escaping characther.
The problem I was having is due to an issue with Libsass, which Gulp-sass uses under the hood to compile sass, instead of the original ruby implementation. Libsass does not need the escaping character, so when I escape to avoid Intellij error, it compiles the escape character as well.
I am using Gulp-ruby-sass now and everything works just fine, meaning I can escape the :host selector the way Intellij provides
I must remove page break while generating pdf by visual force pdf, but whatever I try with css page-break-inside: avoid;, page-break-before: avoid; etc. is not working.
I want to remove all page breaks making it a continuous pdf page, but I cannot figure it out.
Instead of using CSS styling for the APEX component, try a div tag around the APEX components you want to not be broken apart with style="page-break-inside:avoid;"
//div style="width:100%;page-break-inside:avoid;"> APEX ///div>
This css page-break-inside: avoid;, page-break-before: avoid; works only when you need to iterate on components. If you are using inline pre-built css into page then you have to check following css related to body tag. like this:
body { box-sizing: border-box; height: 11in; margin: 0 auto; overflow: hidden; padding: 0.5in; width: 8.5in; }
Here I am using width and height with auto value.
