I use a couple of <link> tags which reference (href) to css files in the HTML code of my pages. They worked fine in Moodle 2.7, but when I use them in Moodle 3.9, they get stripped out of the code when I go back to the Atto editor or when I save and display. Because the code gets removed, the pages don't display with the correct styles.
The tags are:
<link href="myfolder/css/special-style-sheet.css" rel="stylesheet" type="text/css">
<link href="https://www.mywebsite.com/css/special-style-sheet.css" rel="stylesheet" type="text/css">
These are at the start of the code for the page. Does anyone know what these <link> tags would be stripped out of the HTML editor when it switches to WYSIWYG?
