mime type not set correctly for webpage

[Diana Eichert]

"I'm trying to get rainloop  PHP webmail setup on a mail server using
OpenBSD 6.9 httpd

I have the webserver configured however the browser shows the mime
type is not correct for the css style sheet.
>From Firefox console,
"The stylesheet
https://mail.shopnet.com/rainloop/rainloop/v/1.16.0/static/css/app.min.css?standard
was not loaded because its MIME type, “text/html”, is not “text/css”.

I included system mime file types in httpd.conf file as below.

Any pointers are appreciated.

thanks
