Lines perform a structural and organizational role in HP’s visual language. They divide layouts into separate, bite size sections or modules but also organize and structure content within modules. They are always functional and should not be misused as decorative features.
Lines are either vertical or horizontal and are either black or white—matching text and logo.
Lines should feel balanced with the type around it, not too thin nor too thick. They appear in only one weight per layout—light but visible—usually 0.5–2 points.
