when i open my website, i get the error

The stylesheet https://skie.lol/styles.css was not loaded because its MIME type, “text/plain”, is not “text/css”.

whenever i try and log onto the website my CSS is not rendered, but the HTML is.
i’m running nginx with the nginx.conf file of

user www-data;
worker_processes auto;
pid /run/nginx.pid;
error_log /var/log/nginx/error.log;
include /etc/nginx/modules-enabled/*.conf;

events{}

http {
        include mime.types;
        include /etc/nginx/conf.d/*.conf/;
        server{
                default_type text/css;
                location / {
                        root /home/git/website-work/www;
                }
                location /images/ {
                        root /home/git/website-work;
                }
                location /lexi/ {
                        root /home/git/website-work;
                }
                location /lexi {
                        root /home/git/website-work;
                }
                location /links/ {
                        root /home/git/website-work;
                }
                location /links {
                        root /home/git/website-work;
                }
                location /quotebook/ {
                        root /home/git/website-work;
                }
                location /quotebook {
                        root /home/git/website-work;
                }
                location /wip/ {
                        root /home/git/website-work;
                }
                location /wip {
                        root /home/git/website-work;
                }
        }
}

also, this is my link in HTML, as i was initially having struggles with this before i realized there was an issue with the MIME type.

<link rel="stylesheet" type="text/css" href="styles.css">

and my mime.types file at /etc/nginx/mime.types has both

text/css    css;
text/plain  txt;

in it. im so lost for why this doesn’t work, i just need help

ive tried:

1. changing my built in linux mime.types, but it had both text/css and text/plain set correctly
2. adding css and txt to both my built in linux and mime.types file, both error-ed out
3. added default_type for mime types into my nginx.conf at http, server, and location level, none did anything
4. setting a specific types “type{text/css css;}” to both server and location. surprisingly it did nothing, which makes me think it didnt work. so that might be able to help if theres a reason that wouldn’t work
5. restarting my server, nginx and web browser multiple times, which has done nothing sadly

im still very new to linux and nginx so if i’ve made a dumb mistake, i apologize a million times

any help is appreciated, thank you
