RulersGuides.js
=================

This Javascript package creates Photoshop-like guides and rulers interface on a web page.

<a href="http://mark-rolich.github.io/RulersGuides.js/" target="_blank"><strong>DEMO</strong></a>

Main window:

Menu:

Guides are created by click-and-dragging corresponding horizontal or vertical ruler.
Guide position is shown while dragging and on mouse over.

It is possible to open/save created guides as grids
(Note: grids will be saved on a page location basis, so it's not possible to use the same grids in another browser window/tab).

Rulers can be unlocked, so that one of the rulers will scroll along the page and the other will be always visible.

Guides can be snapped to defined number of pixels.

Detailed info mode is available, which shows position and size of regions created by the guides.
Works on guide position change too.

Guides can be snapped to DOM elements (experimental, use with caution, can be slow or unresponsive on complex pages with lots of elements).

Following hotkeys are available:

* Toggle rulers - `Ctrl + Alt + R`
* Toggle guides - `Ctrl + Alt + G`
* Toggle rulers and guides - `Ctrl + Alt + A`
* Clear all guides - `Ctrl + Alt + D`
* Save grid dialog - `Ctrl + Alt + S`
* Open grid dialog - `Ctrl + Alt + O`
* Lock/unlock rulers - `Ctrl + Alt + L`
* Open Snap to dialog - `Ctrl + Alt + C`
* Toggle detailed info - `Ctrl + Alt + I`
* Toggle snap to DOM - `Ctrl + Alt + E`

Look-and-feel can be adjusted using CSS.

RulersGuides.js is available as a bookmarklet, please see bookmarklet.js file provided with the package.

For IE users there is a bookmarklet_ie.js file, which loads necessary packages externally due to IE bookmark size restriction.

You can copy and include them locally by changing paths in the bookmarklet.

RulersGuides.js is available as an extension for Google Chrome browser, download it [here](http://mark-rolich.github.io/RulersGuides.js/RulersGuides.crx),
and drag and drop downloaded file to extensions tab (chrome://extensions).
