Overview

Vendored Google Closure Library module providing common element positioning code used by Selenium JavaScript atoms.

Description

goog.positioning is a vendored copy of the Google Closure Library module. It provides common positioning logic for UI elements, including enums for CornerBit (BOTTOM, CENTER, RIGHT, FLIP_RTL), Corner (TOP_LEFT, TOP_RIGHT, BOTTOM_LEFT, etc.), Overflow handling (IGNORE, ADJUST_X, ADJUST_Y, etc.), and OverflowStatus. These are used for positioning popups and other UI elements relative to anchor elements. Selenium uses this as part of its JavaScript atom infrastructure.

Usage

This module is consumed internally by Selenium's JavaScript atoms build system. Not imported directly by end users.
