LESS css variable not working - css

I am new to LESS and I'm using less.js as to my development environment. The problem is, when I declare a variable, it doest not working like nothing happen.
#bground: #c0c9c8;
body{
background-color: #bground;
}
As you can see, the #bground does not pass it value. If I put direct value it will apear which is proof the .less is set up correctly. I'm using latest version of Chrome and running locally on Mac. Everything is working except variable. Without variables in work, I cannot use the LESS feature.

If you`re using apache, create an .htaccess file in your root folder, if you already have one, just add this line:
AddType text/css .less
This will tell apache to send the right content-type header for the .less file

Please make sure you loaded less js file in your page to accommodate less file.
use
<script src="//cdn.jsdelivr.net/npm/less" ></script>
for that.
Also while loading your less file use following syntax
<link rel="stylesheet/less" type="text/css" href="dist/css/<your less file>.less" />
make sure you use rel and type attributes on the tag, as mentioned.

Include Bootstrap/Semantic UI locally in an Express project?

I downloaded the minified version of bootstrap and put it in the root directory of my project. Then in a HTML file in /views/ I added:
<link rel="stylesheet" href="/bootstrap.min.css">
However, the page continued to look the same because Bootstrap styles weren't added. I know I can use a CDN, I did and it worked, but for now I want to try including it locally. I tried to similarly include Semantic-UI but it didn't work too. What am I doing wrong?
I think I figured it out. Assuming that you have your stylesheet in /public then you have to add this line to your application file (usually app.js):
app.use(express.static(path.join(__dirname, 'public')));
From now on you can link to your stylesheets from anywhere in the project using this code:
<link rel="stylesheet" href="/bootstrap.min.css">
Note that we no longer have to specify the full path, which is "/public/bootstrap.min.css" - we omit the "/public" (in fact href="/public/bootstrap.min.css" would be an error).
If anybody reading this can explain why the first line is necessary please comment below. I believe I understand what it does but why the Express creators insisted on doing it that way i.e. why can't I <link> to my local files normally is what I don't get.

Concrete5 Appending Paths

I wanted to post out to the community in an effort to try and pin down a recent issue I've been having in regards to pulling in custom fonts.
When I initially set up my site to try and import a custom font, I followed the guide here (http://www.concrete5.org/documentation/how-tos/designers/how-to-add-a-custom-font-face-to-your-theme/) and thankfully I was able to pull in my fonts.css file that I needed.
Unfortunately, just recently I went ahead and made some customizations to the theme I was using (Under Page Settings > Design). After I had saved those changes however, I noticed that my fonts we're no longer being referenced and I was getting 404 errors when trying to pull that fonts.css file.
Now in my header file, I was referencing the fonts.css file relatively which worked until I made the customizations to the theme. Now it seems as though it's changed the 'location/directory' of where these pages, or at least the header file is. The differences in what I've put into the header file, and what's being appended are below.
Before:
<link rel="stylesheet" type="text/css" href="<?php echo $this->getStyleSheet('../fonts/raleway/fonts.css')?>" />
Now:
<link rel="stylesheet" type="text/css" href="/index.php/ccm/system/css/page/157/../fonts/raleway/fonts.css" />
In particular, I'm noticing that
/index.php/ccm/system/css/page/157/
is now being appended, which is obviously causing the reference to fail. My question is, is there any way that I can reset concrete5 so that I will stop appending this reference, or a way to set a direct path (which is /application/files/cache/css/fonts/raleway/fonts.css) in my header file?
As for other information, I do have Pretty URL's enabled all appropriately (as far as I can tell). And I've set the location of all my pages within their own page, rather than all being built from the index.php page.
If there's anything you guys might need from me, just feel free to let me know. Again, if there's any way that I can get this resolved, I'd greatly appreciate it!
Despite its name, getStylesheet in concrete 5.7 and greater only works with LESS files, not .css files. It's also not set up to handle ".." in the path of files. If you pass a .css file to getStylesheet it will run the file through the LESS parser, which may double-encode things. You might not notice any problems with this, but it's best to avoid it altogether if possible.
Here's how I would add a custom font face to my theme.
First, make sure your theme's directory contains the "fonts/fonts.css" file with your custom font face directives in it.
Then, include the file this way in your theme:
<link rel="stylesheet" type="text/css" href="<?php echo $view->getThemePath()?>/fonts/fonts.css" />
This will only work if "fonts" the directory appears at the root level within your theme's directory – but it should be all you need to do.

How to link style.less in Asp.net Webform?

Today I discovered less stylesheet and egor to learn it.
But i am confuses it is showing inside inspect element Internel Server error 500 in linking less.
I first install it via command in nuget console
ie
PM -> install-package dotless
and then relate the stylesheet in my header content like
<link rel="stylesheet" type="text/less"
href="Content/style.less" />
Is this correct way? If not help required.
The style you used is only recommended for debugging. You need to add the style.js script to your site, like below. You may also need to make sure your server is configured to serve .less files by adding the MIME type to your site configuration.
<script src="less.js" type="text/javascript"></script>
But no, that is not the correct way for production use. Your browser has no idea what LESS is. Your browser understands CSS only. For test purposes, less.js is able to convert .less files into a usable form, but it's not recommended for production use.
Instead, the point of LESS is that it compiles to CSS. Then you provide that CSS as your stylesheet in the traditional way. The LESS documentation should help you out. As a quick example, here's how you'd compile LESS to CSS.
lessc styles.less > styles.css
In the above command, lessc is the compiler program. styles.less is your LESS sheet being passed to the compiler. The output would normally go to STD OUT and you'd see it in the console, but since we included > styles.css we're redirecting that STD OUT into a text file called styles.css.

Twitter Bootstrap LESS css

I am wondering why I cant set variables within twitter bootstrap using LESS. I am using ruby on rails which has a bootstrap_and_overrides.css.less file. it has the following statement
// Your custom LESS stylesheets goes here
//
// Since bootstrap was imported above you have access to its mixins which
// you may use and inherit here
//
// If you'd like to override bootstrap's own variables, you can do so here as well
// See http://twitter.github.com/bootstrap/less.html for their names and documentation
//
// Example:
// #linkColor: #ff0000;
So my understanding is that i can set my variables within here. So i set
#black: #333;
and then tried using it in my application.css calling #black file but it does not work? i.e. doesn’t render #333.
Am i understanding this incorrectly?, do all my variables and css styling go within the bootstrap and override file?
Any advice appreciated
Follow the instructions at http://lesscss.org/#usage to make sure your updated less is used, if you are using it client side.
OR
Compile your updated less into CSS and then copy over the updated CSS.
Here's a list of tools that can do the compile. http://bootstrap.lesscss.ru/less.html#compiling
For suggestions on how to organize your bootstrap modifications see the SO question Twitter Bootstrap Customization Best Practices
As an aside, I wouldn't recommend changing #black. Changing it would alter many, many things, including some you might not expect.
If I understood you correctly, you are modifying your bootstrap_and_overrides.css.less file, but the one being used is the application.css file.
If that was the case, of course it's is just natural not to reflect the changes you've made. You must compile your .less file first to .css. to reflect that changes to your .css file.
For a try, use LESS via the client-side and setup your environment like so:
For instance, in your index.html file, put
<link rel="stylesheet/less" type="text/css" href="application.less" />
in the document head. and below it add
<script src="less.js" type="text/javascript"></script>
Download the less.js file from here. and put it inside your root directory, or you may of course customize the location and make the necessary path in the href attrib.
After doing the above, you're ready to modify your application.less file (not the application.css). You may copy you're existing custom styles from the application.css file.
application.less is where you should put your variables.
You may rename your bootstrap_and_overrides.css.less file into application.less and make sure it is the one linked to in the header tag.

can you not compress CSS but work on it later?

I've even looked at CSS Crush, Minify, SmartOptimizer, CSSTidy and a slew of other PHP CSS compressors. But they all have one major flaw.
You can't use this:
<link rel="stylesheet" href="css/styles.css" type="text/css">
When using dreamweaver, this is the only way to see the DESIGN in DESIGN VIEW. If you replace that styles.css file with styles.php, it breaks, even if you HAVE css code in the file..
I am using minify for my JS and it is working beautifully, but if I use it with CSS, Dreamweaver gets scared and doesn't know how to render it. haha. Of course, it IS server side though.
Does anybody have a workaround for a situation like this? I do prefer to use dreamweaver because of the immediate changes that can be made in design view, as well as the FTP capabilities and code hinting, but even the new CS6 seems to whine when you use anything BUT a .css file.
I can't verify that this solution will work, but it should theoretically.
First, you'll want to add .css files as PHP, so you don't have to change the file extension. This is good practice regardless, since the file extension should indicate what content is being delivered. I don't know that there's any standard that states this outright, but it's good practice. If you're using Apache, you can add this to your .htaccess or global server configuration file:
AddHandler php5-script .css
Then, just <link rel="stylesheet" href="css/style.css" type="text/css" /> after renaming your file back to CSS. For more details on this, see the Apache docs on AddHandler.
Second, you'll want to 'comment out' your PHP code within your CSS. For example, you could do something like this at the top of style.css:
/*
<?php include 'your-file-compressor.php'
// Put any PHP code for compression here
?>
*/
That way, Dreamweaver will still read the actual CSS code, but PHP should be able to compress before delivering it to clients.
As Kishore pointed out, Minificaiton should be part of build process. While development you should use the raw css file.
Instead of href="css/styles.php" its better to use href="compresscss/path/css/styles.css". Here compresscss/path/css/styles.css is mapped to compresscss.php?path=css/style.css. This can be done by mod_rewrite in apache.
This way dreamweaver will see it as an css file and also you will compress it.
