It does obviously not bother me, but I am just wondering whether there is a technical reason for having the CSS contents inline in the HTML source code, instead of a dedicated .CSS file, referenced to using <link rel="stylesheet" href="custom.css" />.

About the priority: I know that whichever comes last out of two identical CSS references (whether in the same style sheet or multiple style sheets of the same page), has the higher priority.

Whether a style sheet CSS is embedded in the HTML source code (<style> … </style>) or outsourced to a separate file (<link rel="stylesheet" href="stylesheet_filename.css" />) makes no difference in terms of priority, as long as the tags are at the same position.

But is there a technical reason for having the custom style sheet inside the HTML source code instead of a separate file?

Probably because css is dynamically generated, as in everything is coded in one language, whether js or whatever is the new old, and then it spits out the whole shit on demand as an html5 soup

Indeed, that's possible.

The CSS generated in the HTML source code is not exactly the same as the CSS code in the editing text fields (the CSS generated in the HTML source code has no /* comments */, all invalid CSS removed, the direct image links instead of %%variables%%, and it lacks some line breaks).

Well it certainly won't let you upload raw text for security reasons, so it passes the whole shit to the shreder in order to remove unnecessary code and unwanted code, evidently

Have you tried add svg image via your css? Because if that works... Well that's a potential security flaw eventually

Something like

body { background-image: url("data:image/svg+xml;utf8,<svg xmlns='http://www.w3.org/2000/svg' width='10' height='10'><linearGradient id='gradient'><stop offset='10%' stop-color='%23F00'/><stop offset='90%' stop-color='%23fcc'/> </linearGradient><rect fill='url(%23gradient)' x='0' y='0' width='100%' height='100%'/></svg>"); }

Of course, it does not work.

But I wonder why that filtered CSS is embedded inside the HTML instead of a separate CSS file.

Not that it bothers me, but I would like to know a technical explanation.
