How to Load HTTPS Assets Securely on HTTPS Pages?

Loading HTTPS Assets on HTTPS Pages

When incorporating external CSS and JS files into website headers and footers, it's crucial to ensure that these assets are loaded securely via HTTPS when the page itself is HTTPS. Some browsers may flag unsecured content, which can compromise user trust.

Solution: Protocol-Relative Paths

To resolve this issue, use protocol-relative paths instead of absolute paths. Absolute paths specify the full URL, including the protocol (e.g., http:// or https://). Protocol-relative paths, on the other hand, omit the protocol and use a double forward slash (//) instead.

Example:

Instead of using:

<link rel="stylesheet" href="http://example.com/style.css">
<script src="http://example.com/script.js"></script>

Use:

<link rel="stylesheet" href="//example.com/style.css">
<script src="//example.com/script.js"></script>

By using protocol-relative paths, the browser will automatically use the same protocol as the parent page, loading the external assets securely (via HTTPS) when the page is loaded over HTTPS. This ensures that all content on the page is loaded securely, improving website credibility and user experience.
