page-computed-style v1.0.2

page-computed-style

A CLI to output the computed style of all the elements of a page.

The resulting CSS will have a rule for each element of the page. Each rule will have an attribute selector, to be able to match the rule with its corresponding element:

[data-computed-style-id='0'] {
  ...
}

[data-computed-style-id='1'] {
  ...
}
...

Prerequisites

Node 6.10.0 or higher, together with NPM 3 or higher.

Installing

npm install -g ncardeli/page-computed-style

Usage

To get the computed style of a page in the standard output, type:

page-computed-style -p http://path/to/page

To write the computed style of a page to a CSS file, type:

page-computed-style -p http://path/to/page -o path/to/file.css

To also write the HTML of the page to a file, type:

page-computed-style -p http://path/to/page -o path/to/file.css -t path/to/file.html

The resulting HTML will be modified to add an attribute to each element of the page, to match it with its corresponding CSS rule.

For help and more options, type:

page-computed-style -h
