API call to fonts.googleapi blocked due to http connection

Describe the bug

The page at 'https://fluidproject.org/' was loaded over HTTPS, but requested an insecure stylesheet 'http://fonts.googleapis.com/css?family=Roboto+Slab:400,300,700,100'. This request was blocked since the content must be served over HTTPS.

To reproduce

Steps to reproduce the behavior:

1. Go to 'https://fluidproject.org/'
2. Right-click and Click on Inspect.
3. Go to Console
4. See error

Screenshot:

Expected behavior

The API call should not be blocked

Technical details

http is not secue and https calls must be based since the base host i.e. fluidproject.org is using https connection and api calls to http cannot be made.
