I'm starting to work on a large application styling files. As Bootstrap 4 offers SASS files, I decided to follow that path.
I have built the following files structure:
theme.scss: general definitios for the theme like colors and fonts. Today there is just one but there could be more in the future.
global.scss: includes Bootstrap, some Bootstrap overrides and application componentes -i.e. a field with its label as part of the top border.
site.scss: general application styles.
additional page-specific SCSS files. I.e.: login.scss.
The problem I'm having is that global.scss -the one that imports Bootstrap- is then imported by site.scss as well as other files like page-specific SCSS files. So, Bootstrap styles end up in more than one compiled CSS. Compiled CSS files are what the application actually references.
I've previously used LESS and I could solve this using #import (reference) "bootstrap" instead of just plain #import "bootstrap". With SASS I haven't been able to find any solution to this problem without modifying Bootstrap core files.
Is there any other recommended way to organize the files and avoid this problem? Am I missing something or doing anything wrong?
Here are the files contents (they are large files but I'm posting only enough contents to show the problem I'm having):
theme.scss
$my-primary-color: #04459a;
global.scss
#import "../theme.scss";
$primary: $my-primary-color;
#import "../../third-party/bootstrap/scss/bootstrap.scss";
%field{
// [...]
}
site.scss
#import "global.scss";
div.field {
#extend %field;
}
// [...]
login.scss (or many other)
#import "global.scss";
// [...]
In the application I'm referencing site.css and login.css (in the loign page, of course) and both of them include Bootstrap styles.
I've built something that works for me, not sure if it's the best solution or which drawbacks it has, though.
I took some ideas from this article: My favored SCSS setup with Bootstrap 4. Here's what I've built:
First I created two SASS files for importing Bootstrap (similar to what the article does with bootstrap/_config.scss but splitted):
bootstrap/_sass-componentes.scss
#import "../../terceros/bootstrap/scss/_functions.scss";
#import "../../terceros/bootstrap/scss/_variables";
#import "../../terceros/bootstrap/scss/_mixins";
bootstrap/_config.scss
#import "_sass-componentes.scss";
// Every other bootstrap file I want to include:
#import "../../terceros/bootstrap/scss/_root";
#import "../../terceros/bootstrap/scss/_reboot";
#import "../../terceros/bootstrap/scss/_type";
// [...]
#import "../../terceros/bootstrap/scss/_utilities";
#import "../../terceros/bootstrap/scss/_print";
Then in global.scss I changed the bootstrap.scss import line to import only bootstrap/_sass-componentes.scss
Finally, in site.scss I included global.scss (such as it was before) and then full Bootstrap files trough bootstrap/_config.scss. **
** After importing _config.scss I also import my Bootstrap customizations. For doing them I followed the recomendation of the linked article although they do not apply directly to my own question.
So I would like to get Codekit to minify all my css + less files Upon save.
In the header of my 'style.less' I am trying to import the 'css' file as a less context like:
#import (less) "normalize.css";
#import (less) "file1.css";
#import (less) "file2.css";
#import (less) "file3.css";
body {....
In the hope it will sort of be 'included' then minified on save. I cant seem to get it to work with any combination of #import, saving the css files as less files.
Can it be done?
So my issue was trying to #import font replacement. When looking inside the font replacement file there was an import happening over another site. I believe this is what was causing the miniification to fail...
Hope this helps someone else.
I just start learning css less and I'm using Less v1.5.0 and WinLess to compile the less file. I have a bunch of code as below:
#import "bootstrap.css";
#import "bootstrap-responsive.css";
.test{
.well;
}
but WinLess give me an error says .well is not defined. I was expecting it to pull out the content of well class from bootstrap.css. So where did I do wrong? Thanks!!
CSS files are not processed by LESS when you import them, therefore you cannot use their classes as mixing.
Import them as LESS files:
#import (less) "bootstrap.css";
#import (less) "bootstrap-responsive.css";
.test{
.well;
}

I'm looking for ways to optimize my WordPress instance. The theme has about 8-10 CSS files that are rendered in the functions.php. Consequently, I do not want to change any file names because that would mean that I have to hack the theme and I want to keep that to a bare minimum.
I want to use SCSS to combine these CSS files into one CSS file and include the new file in the theme instead. When I try...
#import "style.css";
#import "reset.css";
#import "shortcodes-styles.css";
It renders as
#import url(style.css);
#import url(reset.css);
#import url(shortcodes-styles.css);
How can I get SCSS to import the CSS as partials without changing the file names? I'm also using CodeKit if that makes a difference.
Not possible. Sass only compiles Sass files: https://github.com/nex3/sass/issues/556
Can you import .css files into .less files...?
I'm pretty familiar with less and use it for all my development. I regularly use a structure as follows:
#import "normalize";
//styles here
#import "mixins";
#import "media-queries";
#import "print";
All imports are other .less files and all works as it should.
My current issue is this:
I want to import a .css file into .less that references styles used in the .css file as follows:
#import "../style.css";
.small {
font-size:60%;
.type;
}
// other styles here
The .css file contains a class called .type but when I try to compile the .less file I get the error NameError: .type is undefined
Will the .less file not import .css files, only other .less ones...? Or am I referencing it wrong...?!
You can force a file to be interpreted as a particular type by specifying an option, e.g.:
#import (css) "lib";
will output
#import "lib";
and
#import (less) "lib.css";
will import the lib.css file and treat it as less. If you specify a file is less and do not include an extension, none will be added.
If you want your CSS to be copied into the output without being processed, you can use the (inline) directive. e.g.,
#import (inline) '../timepicker/jquery.ui.timepicker.css';
I had to use the following with version 1.7.4
#import (less) "foo.css"
I know the accepted answer is #import (css) "foo.css" but it didn't work. If you want to reuse your css class in your new less file, you need to use (less) and not (css).
Check the documentation.
Change the file extension of your css file to .less. You don't need to write any LESS in it; all CSS is valid LESS (except of the MS stuff that you have to escape, but that's another issue.)
Per Fractalf's answer this is fixed in v1.4.0
From the LESS website:
If you want to import a CSS file, and don’t want LESS to process it,
just use the .css extension:
#import "lib.css"; The directive will just be left as is, and end up
in the CSS output.
As jitbit points out in the comments below, this is really only useful for development purposes, as you wouldn't want to have unnecessary #imports consuming precious bandwidth.
Try this :
#import "lib.css";
From the Official Documentation :
You can import both css and less files. Only less files import
statements are processed, css file import statements are kept as they
are. If you want to import a CSS file, and don’t want LESS to process
it, just use the .css extension:
Source : http://lesscss.org/
If you just want to import a CSS-File as a Reference (e.g. to use the classes in Mixins) but not include the whole CSS file in the result you can use #import (less,reference) "reference.css";:
my.less
#import (less,reference) "reference.css";
.my-class{
background-color:black;
.reference-class;
color:blue;
}
reference.css
.reference-class{
border: 1px solid red;
}
*Result (my.css) with lessc my.less out/my.css *
.my-class {
background-color: black;
border: 1px solid red;
color: blue;
}
I'm using lessc 2.5.3
If you want to import a css file that should be treaded as less use this line:
.ie {
#import (less) 'ie.css';
}
since 1.5.0 u can use the 'inline' keyword.
Example: #import (inline) "not-less-compatible.css";
You will use this when a CSS file may not be Less compatible; this is because although Less supports most known standards CSS, it does not support comments in some places and does not support all known CSS hacks without modifying the CSS.
So you can use this to include the file in the output so that all CSS will be in one file.
