CSS doesn't work on HTTPS pages in Chrome and IE

Question

On my site, Chrome can't load a stylesheet if the page is opened with https.

For instance, on the page test.php I have the following CSS include:

<link href="http://www.domain.com/css/mainstyle.css" rel="stylesheet" type="text/css">

It uses the absolute path because there's a lot of SEO, subdirectories etc, so it's much easier to include it like this than by looking for relative paths.

If I open the page as http://www.domain.com/test.php it works fine, but if I open it as https://www.domain.com/test.php Chrome refuses to load the stylesheet!

It works in Firefox and Safari. I can understand IE being a 'special needs' browser, but why is Chrome doing this and how can I fix it?

Calling the CSS file with https://domain.com/css/mainstyle.css fixes the issue, but is it really necessary?

Answer 1

Maybe try Protocol Relative URLs :

< link href="//www.domain.com/css/mainstyle.css" rel="stylesheet" type="text/css" >
