Border frame

An edge around the content clearly separates its area.

Visual traits

• Continuous edge
• Inside-outside separation

Expected changes

• A continuous edge is more likely to appear around the content
• The content area is more likely to be distinct

Definition

A layout element that places a continuous edge around a page, image, or information to separate inside from outside. It does not determine a particular decorative style, subject, or final format.

In more detail

It clarifies a content area with a line, band, or edge of whitespace. Line weight, color, ornament, and content can be adjusted separately.

Includes

• A continuous enclosing frame that separates an area

Excludes

• A box enclosing only a short note
• A temporary crop boundary
• A particular decorative style or output format

What this does not imply

• A particular decorative style, color, or subject
• A small box for captions
• A final format such as print

Variability

The frame may be restrained or ornate, but it retains its enclosing role.

Usage

• Specify only the enclosing element
• Specify decorative style and content separately

Distinguish similar expressions

• Specify a caption box when enclosing only a note

Typical uses

• Define the edge of a page
• Separate a content area from its background

Possible failure modes

• The sides fail to connect and become mere divider rules
• It competes with the content and reduces legibility
