# saucxs/watermark-dom

watermark.js是基于DOM对象实现的BS系统的水印，确保系统保密性，安全性，降低数据泄密风险，简单轻量，支持多属性配置，动态计算水印，水印防被删（监听水印组件元素删除并重新添加，监听改变水印的属性并重新添加）。1、支持2种方式导入使用，2、水印插件-testTool（测试工具），3、内置3种全局API方法，等等。欢迎访问：

## What it is
watermark-dom is a lightweight JavaScript library that adds configurable text watermarks to web pages using DOM elements, Shadow DOM, and pointer-events. It includes anti-tampering protection that detects deletion or modification of the watermark and automatically re-adds it.

## Use cases
- add a watermark to a web page to deter screenshots and data leaks
- prevent users from deleting or hiding a page watermark
- overlay user identity info on internal admin systems
- protect confidential dashboard content with a visible watermark
- dynamically compute and tile watermarks across a page

## When to choose
- you need a simple, lightweight browser-side watermark for a BS web system
- you want tamper-resistant watermarks that reappear after deletion
- you need configurable watermark properties (text, opacity, angle, density)

## When to avoid
- you need server-side or image/video watermarking rather than DOM overlays
- you require strong security guarantees - DOM watermarks can be bypassed by determined users
- you need canvas-based or PDF watermarking
