As each CSS property needs to be manually built to be supported, there are a number of properties that are not yet supported.

Before you get started with the script, there are a few things that are good to know regarding the
|
||||
script and some of its limitations.
|
||||
|
||||
## Introduction
|
||||
The script allows you to take "screenshots" of webpages or parts of it, directly on the users browser.
|
||||
The screenshot is based on the DOM and as such may not be 100% accurate to the real representation
|
||||
as it does not make an actual screenshot, but builds the screenshot based on the information
|
||||
The screenshot is based on the DOM and as such may not be 100% accurate to the real representation
|
||||
as it does not make an actual screenshot, but builds the screenshot based on the information
|
||||
available on the page.
|
||||
|
||||
## How it works
|
||||
The script traverses through the DOM of the page it is loaded on. It gathers information on all the elements
|
||||
there, which it then uses to build a representation of the page. In other words, it does not actually take a
|
||||
screenshot of the page, but builds a representation of it based on the properties it reads from the DOM.
|
||||
|
||||
|
||||
As a result, it is only able to render correctly properties that it understands, meaning there are many
|
||||
CSS properties which do not work. For a full list of supported CSS properties, check out the

[supported features](/features/) page.
|
||||
|
||||
## Limitations
|
||||
All the images that the script uses need to reside under the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy)
|
||||
for it to be able to read them without the assistance of a [proxy](/proxy/). Similarly, if you have other `canvas`

All the images that the script uses need to reside under the [same origin](http://en.wikipedia.org/wiki/Same_origin_policy)
|
||||
for it to be able to read them without the assistance of a [proxy](/proxy/). Similarly, if you have other `canvas`
|
||||
elements on the page, which have been tainted with cross-origin content, they will become dirty and no longer readable by html2canvas.
|
||||
|
||||
The script doesn't render plugin content such as Flash or Java applets.
