HTTP or Hypertext Transfer Protocol is simply the method of transferring data over a network. Often, it comes through in two types: requests and responses. All users want and expect the websites they enter to be secure and to protect their online privacy.
HTTPS is the secure version of Hypertext Transfer Protocol. Implementing HTTPS or Hypertext Transfer Protocol Secure is one way to ensure the security of your website. This online communication protocol protects the data exchanged between a user’s computer and your website. As long as you have HTTPS, your website is secure — no matter what type of content you have on it.

What Does “HTTP Page Links To HTTPS CSS” Mean?
When you encounter this problem, it means your URLs may change to an insecure Hypertext Transfer Protocol connection when they’re using a more secure protocol link.
What Triggers This Issue?
The issue occurs when mixed content loads over HTTP and HTTPS. Often, the content includes HTML pages and links to resources like images, CSS, or JavaScript. The resources often load without warning over the insecure HTTP connection. Meanwhile, the HTML page goes to the secure Hypertext Transfer Protocol connection. The issue also gets triggered by the default blocking of requests from insecure sources.

Why Is This Important?
If you have this problem, it can diminish the security quality of your website. It can also affect the users’ experience and force them to redirect their attention to other websites that seem more secure instead. It may also impact the reputation of your website if you don’t fix this problem immediately.
How To Fix the Issue
The proper way to resolve this issue is to make all your content into HTTPS. It would help if you also fixed your links so that they aren’t blocked by the website or browser.
If you are the domain owner, consider turning the link into an HTTPS version simply by adding an “s” to the link. In other words, turn “http://” into https://”.
If the CSS files are on other domains and hosted there, use the website’s HTTPS version. If it’s not available, contact the domain provider or the host. Ask if they can make the content available as Hypertext Transfer Protocol Secure instead.
