Modern CSS includes custom properties (variables). Portal Access does not support them. When a custom property contains some external URL values, this value cannot be rewritten.
Web application may not work correctly.
CSS file or HTML STYLE element with custom property inside, for example: :root { --iset: image-set(url("/images/image-384.jpg") 1x, url("/images/image-768.jpg") 2x,); } .img { background-image: var(--iset); }
Use iRules to substitute 'var()' function calls in CSS files with the corresponding custom property values.
Now Portal Access supports CSS custom properties in server-side CSS parser.
