How does the display property of the `` element affect the behavior of anonymous block boxes and the styling of content within them?

display:block Inside display:inline

Consider the following scenario: an HTML document with a <body> element styled with display:inline and a element styled with display:block. According to the CSS 2.1 specification, this setup results in:

"An anonymous block box around the <body>, containing an anonymous block box around the anonymous text before the , the block box, and another anonymous block box around the anonymous text after the ."

Visually, the resulting boxes are represented as:

+- anonymous block box around body ---+
| +- anonymous block box around text 1-+ |
| |                                 + |
| +---------------------------------+ |
|                                     |
| +- P block box -------------------+ |
| |                                 + |
| +---------------------------------+ |
|                                     |
| +- anonymous block box around text 2-+ |
| |                                 + |
| +---------------------------------+ |
+-------------------------------------+

However, the behavior of this setup differs from that of <body style="display:block;">. As per the CSS 2.1 specification:

"Properties set on elements that cause anonymous block boxes to be generated still apply to the boxes and content of that element."

This distinction is visible with properties like "border-style". In the case of <body style="display:inline;">, the border will surround the anonymous text before and after the element, leaving the element unchanged. In contrast, with <body style="display:block;">, the border will surround the entire body element, including the element.
