When trying to display in CSS the SASS variable that I declared, I don't get the variable itself in the CSS output file, but the value given to the variable.
To be more clear, this is what I get:
SCSS/SASS input
$gray__background: #2d2d2d;
:root {
--gray__background: #{$gray__background};
}
body{
background-color: $gray__background;
}
CSS "output"
:root {
--gray__background: #2d2d2d;
}
body{
background-color: #2d2d2d;
}
That's what I was expecting to get:
CSS "output"
:root {
--gray__background: #2d2d2d;
}
body{
background-color: var(--gray__background);
}
Short story: I want to know if the result in the CSS "auto generated" file background-color: var(--gray__background);, instead of background-color: #2d2d2d; is possible to achieve.
I use the Live Sass Compiler extension for VSCode.
Sorry if my question is a little bit vague. I'm new to coding.
The :root variables are being declared in the SCSS, but are not being used, so they wouldn't show up on the CSS output.
It looks like you'll have to use --gray__background in the SCSS rather than $gray__background so it becomes: background-color: var(--gray__background);
.
Hope this helps.
I keep getting this error in css. This screenshot is on dreamweaver. I have also tried on brackets and codesandbox. Nothing seems to be working.

To answer your question you are using a valid SASS or SCSS with nested classes in a .css file and hence the error is shown. You can use this link to convert SASS to CSS: SassMeister
The equivalent css would be:
header {
display: flex;
height: 140px;
background-color: #A7ACB1;
}
header nav {
flex: l;
}
header nav ul {
list-style: none;
margin: 0;
padding: 0;
}

I'm working on a CSS file and I'd like it to interact with anothet CSS file.
How? Let's say I have A.css and B.css. In A.css I want to do the "overflow: hidden" referred to B.css and all the elements that it controls.
Is anything like that impossible?
Like:
#import "field.css"
.sky .field {
overflow:hidden;
}
So basically this what I actually have:
.sky {
width: 90%;
height: 100%;
background: blue;
opacity: 0.7;
position: absolute;
z-index: 1;
}
.field {
width: 100%;
height: 20px;
background: green;
position: fixed;
top: 90%;
z-index: 2;
}
.field > p {
width: 100%;
height: 40px;
background: black;
}
Now I want that "p", which is a sub-tag of .field to not show outside of the bounds of .sky.
How do I do that?
No need to import one CSS file into the other simply link to both CSS files in your HTML. For example if you had the following two files
File A:
.sky .field {
overflow:hidden;
}
File B:
.sky {
color: black;
}
Sky would inherit both properties of overflow hidden and color black. If the rules contradict each other for example file A says sky color is blue and file B says black then the CSS rule sheet which is linked last will take presidence.
Edit: Generally it isn't good practise to do this for organization purpose. If Sky is a single objection consider putting all CSS references to it in a single file.
Load both the CSS files into your page. You can actually have multiple files which define style rules on same element. So lets say you have two file
File 1
.sky{
background-color: Red;
}
And File 2
.sky.field {
overflow:hidden;
}
And lets say the page has a element with class div and field.
<div class='sky field'></div>
Now this will have both the combined CSS rules.
Also make sure you get yourself familiar with CSS Priorities, If 2 files have the different CSS rule on the same element then what happens??
Example
//File 1
.sky{
background-color: Red;
}
//File 2
.sky.field {
background-color: Blue;
}
Now the file that is placed last in the HTML DOM will have more priority over other rules. Note that its NOT the last file loaded but the last file in the DOM hirarchythat gets the priority.
(Posts such as MVC #import html keyword show similar problems to mine, but the solution does not seem to fix my problem.)
I am trying to use the below code within a .cshtml file. The css #import conflicts with Razor, so I tried ##import but to no avail. I get runtime errors in Visual studio such as "The controller for path '/media/css/site_jui.ccss' could not be found."
<style type="text/css" media="screen">
#import "/media/css/site_jui.ccss";
#import "/release-datatables/media/css/demo_table_jui.css";
#import "/media/css/jui_themes/smoothness/jquery-ui-1.7.2.custom.css";
/*
* Override styles needed due to the mix of three different CSS sources! For proper examples
* please see the themes example in the 'Examples' section of this site
*/
.dataTables_info { padding-top: 0; }
.dataTables_paginate { padding-top: 0; }
.css_right { float: right; }
#example_wrapper .fg-toolbar { font-size: 0.8em }
#theme_links span { float: left; padding: 2px 10px; }
</style>
You can use double # to escape the #:
##import "/media/css/site_jui.css";
This will work:
#string.Format("#")import "/media/css/site_jui.css";
I originally wanted to include a .css in my HTML doc that loads multiple other .css files in order to divide up some chunks of code for development purposes.
I have created a test page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<link rel='stylesheet' href='/css/main.css'>
<link rel='stylesheet' href='/css/site_header.css'>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>

</head>
<body>
<div id="site_container">

<div id="site_content">

</div>
<div id="site_footer"><?php include_once($r->base_dir . "inc/site_footer.inc.php"); ?><!-- Include File, Update on ajax request. --></div>

</html>
File: /css/main.css
/* Reset Default Padding & Margin */
* {
margin: 0;
padding: 0;
border: 0;
}
/* Set Our Float Classes */
.clear { clear: both; }
.right { float: right; }
.left { float: left; }
/* Setup the main body/site container */
body {
background: url(/images/wallpaper.png) repeat;
color: #000000;
text-align: center;
font: 62.5%/1.5 "Lucida Grande", "Lucida Sans", Tahoma, Verdana, sans-serif;
}
#site_container {
background-color: #FFFFFF;
height: 100%;
margin-left: auto;
margin-right: auto;
text-align: left;
width: 100%;
}
/* Some style sheet includes */
/* #import "/css/site_header.css"; */
/* Default Font Sizes */
h1 { font-size: 2.2em; }
h2 { font-size: 2.0em; }
h3 { font-size: 1.8em; }
h4 { font-size: 1.6em; }
h5 { font-size: 1.4em; }
p { font-size: 1.2em; }
/* Default Form Layout */
input.text {
padding: 3px;
border: 1px solid #999999;
}
/* Default Table Reset */
table {
border-spacing: 0;
border-collapse: collapse;
}
td{
text-align: left;
font-weight: normal;
}
/* Cause not all browsers know what HTML5 is... */
header { display:block;}
footer { display:block;}
and now the file: /css/site_header.css:
#site_header {
background-color: #c0c0c0;
height: 100px;
position: absolute;
top: 100px;
width: 100%;
}
Problem:
When I use the above code, the site_header div does not have any formatting/background.
When I remove the link line from the HTML doc for site_header.css and instead use an #import url("/css/site_header.css"); in my main.css file, the same results -- nothing gets rendered for for the same div.
Now when I take the CSS markup from site_header.css and add it to main.css, the div gets rendered fine...
So I am wondering if having multiple css files is somehow not working... or maybe having that css markup at the end of my previous css is somehow conflicting, though I cannot find a reason why it would.
The #import directive has to come first in your CSS. As soon as one style is hit by the browser, all other import lines will be ignored.
To quote WC3:
"any #import rules must precede all
other rules (except the #charset rule,
if present)"
See http://www.w3.org/TR/CSS2/cascade.html#at-import
One thing to consider, is that each #import still causes an HTTP request, so it's not any more efficient than using multiple link tags. In fact it may be less efficient as imports may be sequential rather than parallel requests. See this article. IMO it also adds complexity because you end up managing CSS references in two places (head tag of markup plus 1 or more CSS files) vs a simple list of link tags.
I'd also recommend where you can combining CSS files when your site is in production as it will reduce HTTP overhead.
Can I just say, pet peeve here, but place images related to the CSS file in the CSS folder itself, not in /images/.
The point of CSS is the separation of style and content, and only content images should go in /images/. Any images called by the CSS should be placed in the same directory and called pathlessly, e.g.:
body {
background: url(wallpaper.png) repeat;
}
That way at a later date if it comes to changing the style, or making multiple styles it's just a case of updating one link and moving one folder (/css/) rather than having a mess of images scattered all over the filesystem. Plus it's always a bad idea to use absolute paths to files (such as /images/wallpaper.png).
First of all, you have invalid markup. The link tag must be closed...
<link rel="stylesheet" href="/css/main.css" />
Second, why don't you use double-quotes consistently for element attributes (here in the link tag you happen to use single-quote)? This is not part of the problem, but I find it daunting that you would intermingle various syntax conventions like this.
Lastly, I would not recommend using #import because it does not offer a compelling benefit. It must be the first thing in the CSS file. An additional HTTP request still has to be made for each of the additional CSS file(s). And on top of that, IE cokes when you to specify a target media for imports. I stick to the good old classic link tag because it just works (given that you have valid markup!).
Use firebug to inspect the div and see what styles are being applied to it, you might get some more insight.
use #import rule into your main.css file like:
#import url("css/site_header.css");(this code should be on top of your main.css)
the above import snippet will bind your multiple css files into single css
then that main.css file use into your HTML.
For any issues with CSS like this I would recommend using firebug. You will be able to see if your site_header.css is loading properly.
If it is loading you will be able to see which styles are being applied to which elements, perhaps some are being overwritten?
