"Add File" and "Add File Here" in Modx File Manager

actually, i’m a little confused because there’s a css file type in the resource editor. How do you get a css resource into the file system?

or don’t you?

if a resource css is stored in the database, how do you reference it in the html page?

CSS is not normally stored in the DB.

You can create a CSS file locally, then right-click on the directory (on the Files tab) and select "upload file".

While it is usual to use an external file for your css, as in style.css, you can also use a MODx resource as the css file. Your browser doesn’t know or care if it is accessing a file or a MODx resource, the server just sends what is requested, so you would use a URL for either one.

- or -

The rel and type attributes tell your browser this is a CSS stylesheet, so whether it’s stored (file) or generated (MODx resource) is irrelevant.

so the second example is used for a css resource, which is stored in the db?

That is correct. Your browser requests a resource via its URL (Universal Resource Locator) which in the case of MODx and other CMS applications can be either generated on demand, or retrieved from the filesystem. It makes no difference at all to the browser.
