I have an application that let's users specify custom css along with our pre-determined css. I'd like it so that when we request the user's css file, we return a file that dynamically compiles the base css with the user-specific css. This is relatively easy to do if we're serving the assets from our own server, but if at some point I'd like to serve all my static assets from a CDN, is there a CDN that would let you do this? I know I could always upload a separate css file for each user to the CDN, but there would be tons of duplication of the base CSS which would unneccessarily raise storage costs.
Why don't you split your CSS into two separate files?
static CSS served by the CDN
dynamic (user generated) CSS served by a script on your server
Your HTML will then look something like this:
<link href="./dynStyles.css" rel="stylesheet" type="text/css" media="all">
<link href="http://my.cdn.com/staticStyles.css" rel="stylesheet" type="text/css" media="all">

I'm currently learning about html and css. I've learnt about this code,
<link rel="stylesheet" href="https://www.w3schools.com/html/styles.css">
It was said that external stylesheets can be loaded with 3 ways, and that's one of the ways.
So my question is, does that mean I have to upload my stylesheet to a specific website so I can access the stylesheet my html document?
ps. sorry for bad english
edit: the link comes from w3schools, i'm learning the basics from there. if i shouldn't have done that please tell me so i can remove it.
The following
<link rel="stylesheet" href="https://www.w3schools.com/html/styles.css">
Will download the styles.css file from www.w3schools.com/html/. In that case, you only have to upload your html file. The downside is that if the w3schools.com admin deletes the file you don't have control over his decision , your page will not find it anymore.
The best thing to do is to put a local my_styles.css file in the same folder as your html file and then
<link rel="stylesheet" href="my_styles.css">
This means you will have to upload your html file and my_styles.css. In this case the style will be always available for the webbrowsers to download.
does that mean I have to upload my stylesheet to a specific website so I can access the stylesheet
No. The stylesheet needs a URL so the browser can access it. It doesn't have to be a URL hosted by a particular website.
It doesn't matter where that URL resolves to (unless it is one that isn't accessible to the browser — e.g. if the URL is on a private LAN and the browser isn't on that LAN).
No it doesn't have to be uploaded anywhere. The href attribute simply expresses where the file is. The value of the href can be relative or absolute.
Relative
Relative paths are relative to the folder your HTML file is in. So imagine you have an HTML page webpage.html and a CSS file styles.css in the following folder structure:
My Website
|-- css
| `-- style.css
|-- images
`-- webpage.html
Your link element could use a relative path like this:
<link rel="stylesheet" href="../css/styles.css">
../ to go up a folder, then css/ to go into the css foler.
Absolute
An absolute path points to the same place no matter where you're pointing from. In the folder structure above, if My Website was the root directory of our website, we could use absolute paths a couple different ways:
<link rel="stylesheet" href="/css/styles.css">
/ to start at the root directory, then css/ to go into the css folder
OR
<link rel="stylesheet" href="http://www.mywebsite.com/css/styles.css">
This would directly load your CSS from the URL like the w3schools example.
https://www.w3schools.com/tags/tag_link.asp
<link rel="stylesheet" type="text/css" href="my_style.css" />
https://www.w3schools.com/tags/att_style_type.asp
<style type="text/css">
...
</style>

I'm working on a web-application built upon the MEAN stack.
I use bootstrap as css lib, and have some css override in two files of mine "app.css" and "mio.css"
the app works just fine until I hit refresh in a controller that handles two partials, than everything gets reloaded except for my 2 css files.
<link href="//netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-combined.no-icons.min.css" rel="stylesheet">
<link href="//netdna.bootstrapcdn.com/font-awesome/3.1.1/css/font-awesome.min.css" rel="stylesheet">
<link rel="stylesheet" href="css/app.css">
<link rel="stylesheet" href="css/mio.css">
If I inspect them they contain the index.html data (head body dcc)
could you suggest what's happening??
Try using full file paths to the css files. For example..
<link rel="stylesheet" href="/assets/css/app.css">
The issue might be on the server side. Since angular apps are single page ajax applications, the server has to redirect all requests to the index.html page EXCEPT for assets. Your server might be returning the index.html page instead of your css files.
An interesting problem but maybe it has already been solved. I have a collection of CSS style sheets that apply to multiple domains. The way it has been architected, both domains share the same CSS files and add their own definitions and rules to the stylesheets. Our system is as such that anytime a developer makes a change to a CSS file that belongs to a particular domain, then that very same change needs to be done in another domain's style sheet as well.
For instance if I have two domains: Main, SubMain. BOth of these share a stylesheet called global.css and a developer working on the SubMain domain changes this stylesheet by adding a new rule. To ensure that things do not break in the Main domain, the developer needs to go ahead and add the same rule to global.css to the main domain's global.css stylesheet.
Why this does not have the same shared location is beyond me since this is a shared engineering project. My understanding is that the reason being that the changes were to be applied immediately and unfortunately the only option was to use the same stylesheet + directory structure across all the domains.
But this problem does exist and it is tremendous overhead. Is there anyway to extend CSS stylesheets such that domain specific CSS can be added to the extended stylesheets.
If not, what other solutions can be proposed ?
If you have the same code in two places, why have two files (and this goes for coding as well - methods or variables or whatever)? If you use something more than, keep it in one place and reference to it everywhere else.
What you need to do is to have the Main website point at a local copy of the CSS file (like so):
<link rel=stylesheet type=text/css href="/global.css">
... and then on the SubMain website, include in your headers a link to the Main website's CSS file (like so):
<link rel=stylesheet type=text/css href="http://mainwebsite.com/css/global.css">
To solve your problem, only have the editable CSS file/files on one domain (the Main one), and then link to them using absolute URLs in the other (SubMain) website.
I dont understand you. I dont know where your problem is. Do you want to add 2 css style sheets?
<link href="style.css" type="text/css" rel="stylesheet" />
<link href="style2.css" type="text/css" rel="stylesheet" />
Or do you want that 2 domains using 1 style sheet?
<link href="http://url.com/style.css" type="text/css" rel="stylesheet" />
Both of the domains can use this. You are not linking in the directory of the style sheet. You put the link of your style in it. This will solve your problem.
Both domains can use one CSS file.
<link rel="stylesheet" type="text/css" href="http://myotherdomain.com/css/global.css">
Just link to one CSS file.
Or if you really want to "sync" them you could create a rsync script but that doesn't make sense.
It's apparent that you know you can include stylesheets across domains:
<link rel=stylesheet type=text/css href="http://example.com/global.css">
But did you know that you can include multiple stylesheets? Create a single stylesheet that has all of the "master" styles and put it in global.css on one of the domains (your choice). The styles unique to each domain can be in a stylesheet specific to that domain.
<link rel=stylesheet type=text/css href="http://example.com/css/global.css">
<link rel=stylesheet type=text/css href="/css/specific.css">
In Eclipse, I created a Dynamic Web Project and a JSP file under WebContent folder. I also created a CSS file under the WebContent folder. Then I use <link rel="stylesheet" type="text/css" href="XXX.css"> in the JSP to link to the CSS file but when I run on web server (Tomcat) the CSS didn't apply. Can someone tell me why?
You must put your web project name before the address path of your css file
Example:
<link rel="stylesheet" href="/YourProjectName/XXX.css" type="text/css">
or in more dynamic way:
<link rel="stylesheet" href="${pageContext.request.contextPath}/XXX.css" />
Have fun :)
You can use: With style.css file in WEB-INF/jsp folder
<style type="text/css">
<%#include file="css/style.css" %>
</style>
NOTE
This however copies the entire source of the CSS file into the HTML
output of the JSP page. In other words, this is a server-side include,
not a client-side resource reference. So you effectively miss the
advantage that the browser can cache static resources and this way you
end up with a bandwidth waste because the very same CSS file is
embedded in every single page. In other words, a bad idea in terms of
performance and efficiency.
as #BalusC described in comment! you want to test your style.css file anyway, this is a solution.
you can use
<link rel="stylesheet" type="text/css" href="path/css">
You should restart eclipse so that it maps all css and javascript files again.
I worked for me.
i'm very confused about how to add css files to a blog a made on django following this tutorial: http://www.programmersbook.com/page/21/Django-Beginner-Tutorial-Part-I/
Basically, i want to add a css style sheet to my blog. I've looked around a bit and seen somethings about static and media files and urls. I read a bit about them on Django's website but coulnd't fully understand them.
So, could anyone kindly tell me how i should display:
<link rel="stylesheet" type="text/css" href="style.css" />
They styles work when i do it internally, but how do i show external stylesheets?
It's right in the Django docs, check here. Follow the instructions there and you will be able to use something like that:
<link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}style.css" />
EDIT:
You should sepearate you "static" files from your templates. So move all your .css, .js and images to one directory in your app (it's default name is /static). Honestly, everything is written in the link provided.
