Zepto Position: A Comprehensive Guide
Zepto is a fast and lightweight JavaScript library for mobile web browsers. It provides a subset of the jQuery API, with a focus on optimized performance for mobile devices. One of its most useful features is the position plugin, which allows you to get or set the position of an element relative to its parent or document.
In this article, we will dive deep into the Zepto position plugin, version 1.0 or later. We'll cover everything you need to know about positioning elements in your web page using Zepto, including how to use the plugin, tips and tricks for common scenarios, and sample code for reference.
Getting Started
To use the position plugin in Zepto, you need to include the zepto.js
file in your HTML document. You can download it from the official website or use a CDN. Once you've included the file, you can access the plugin by calling the position() method on a Zepto-wrapped element.

The position()
method returns an object with the following properties:
- top: The vertical distance between the element's top edge and its parent's top edge.
- left: The horizontal distance between the element's left edge and its parent's left edge.
- width: The width of the element.
- height: The height of the element.
You can also pass an argument to the position() method to set the position of the element.

This sets the top and left properties of the element to 100 and 200 pixels, respectively.
Tips and Tricks
Absolute Positioning
You can use the position plugin to get or set the absolute position of an element on the page. To do this, you need to get the position of the element relative to its parent, and then add the position of the parent relative to the document.
