Welcome to the documentation for the Position library!
Overview
The Position library is a powerful tool for managing the positions of elements within a web page. Whether you need to center an element, position it relative to another element, or align it with precision, this library has you covered.
Installation

Usage
To use the Position library, follow these steps:
Centering Elements
To center an element both vertically and horizontally within its parent container, use the centerElement
function:
// Syntax
position.centerElement(elementSelector);
// Example
position.centerElement(".my-element");
Relative Positioning
To position an element relative to another element, use the positionElement
function. This allows you to set the top, bottom, left, or right position of the element:
// Syntax
position.positionElement(elementSelector, positionRelativeTo, options);
// Example
position.positionElement(".my-element", ".target-element", {
top: "10px",
left: "20px"
});
Precision Alignment
For precise alignment, use the alignElement
function. This allows you to align an element’s edges or center with another element’s edges or center:
// Syntax
position.alignElement(elementSelector, alignWithSelector, options);
// Example
position.alignElement(".my-element", ".target-element", {
align: "top left"
});
