Are there specific elements that fall under the umbrella of CSS?

Code is causing some red boxes to appear unexpectedly.

User agent: Chrome/80.0.3987.149 Linux x86_64

Here is the code snippet:

<html lang="en">

<head>
    <meta charset="utf-8">
    <title>Flow</title>
    <base href="/">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="icon" type="image/x-icon" href="favicon.ico">
    <link rel="stylesheet" type="text/css" href="assets/css/b.css">
    <style>
        /* aaaaaaaaaa */
    </style>
</head>

<body>
    <style>
        *:not(body):not(p) {
            color: red;
            font: 18px serif;
            height: 100px;
            width: 100px;
            overflow: auto;
            display: block;
            border: 1px red solid;
        }
    </style>
</body>

</html>

Could this be a bug in the code?

Answer №1

"unique" has no specific definition in the world of HTML or CSS.

*:not(body):not(p) will target every element that is not a body or a p, encompassing html, head, meta, and more.
