# 2.2.0
|
||||
|
||||
* Added an option to set the starting index, useful to mitigate conflicts with
|
||||
third-party CSS files.
|
||||
* Performance improvements, including O(1) lookup of cached values rather than
|
||||
O(n), aborting PostCSS walk altogether when a negative index is found, and
|
||||
not running an optimize step if there are no z-index declarations.
|
||||
|
||||
# 2.1.1
|
||||
|
||||
* Fixes an issue where all positive indices before a negative index were
|
||||
transformed (thanks to @niccai).
|
||||
|
||||
# 2.1.0
|
||||
|
||||
* Now aborts early when encountering negative indices, making the transform
|
||||
safer overall.
|
||||
|
||||
# 2.0.1
|
||||
|
||||
* Improved performance of the module by sorting/deduplicating values in one pass
|
||||
instead of per-value (thanks to @pgilad).
|
||||
|
||||
# 2.0.0
|
||||
|
||||
* Upgraded to PostCSS 5.
|
||||
|
||||
# 1.1.3
|
||||
|
||||
* Improved performance by iterating the AST in a single pass and caching nodes for the second iteration.
|
||||
|
||||
# 1.1.2
|
||||
|
||||
* Documentation/metadata tweaks for plugin guidelines compatibility.
|
||||
|
||||
# 1.1.1
|
||||
|
||||
* Corrected dependency tree when installing from npm.
|
||||
|
||||
# 1.1.0
|
||||
|
||||
* Now uses the PostCSS `4.1` plugin API.
|
||||
|
||||
# 1.0.1
|
||||
|
||||
* Adds a JSHint config, code tidied up.
|
||||
|
||||
# 1.0.0
|
||||
|
||||
* Initial release.

# [postcss][postcss]-zindex [][ci] [][npm] [][deps]
|
||||
|
||||
> Reduce z-index values with PostCSS.
|
||||
|
||||
## Install
|
||||
|
||||
With [npm](https://npmjs.org/package/postcss-zindex) do:
|
||||
|
||||
```
|
||||
npm install postcss-zindex --save
|
||||
```
|
||||
|
||||
## Example
|
||||
|
||||
Sometimes, you may introduce z-index values into your CSS that are larger than
|
||||
necessary, in order to improve your understanding of how each stack relates to
|
||||
the others. For example, you might have a modal overlay at `5000` and the dialog
|
||||
for it at `5500` - so that modal classes occupy the `5xxx` space.
|
||||
|
||||
But in production, it is unnecessary to use such large values for z-index where
|
||||
smaller values would suffice. This module will reduce all z-index declarations
|
||||
whilst respecting your original intent; such that the overlay becomes `1` and
|
||||
the dialog becomes `2`. For more examples, see the [tests](test.js).
|
||||
|
||||
### Input
|
||||
|
||||
```css
|
||||
.modal {
|
||||
z-index: 5000
|
||||
}
|
||||
|
||||
.modal-overlay {
|
||||
z-index: 5500
|
||||
}
|
||||
```
|
||||
|
||||
### Output
|
||||
|
||||
```css
|
||||
.modal {
|
||||
z-index: 1
|
||||
}
|
||||
|
||||
.modal-overlay {
|
||||
z-index: 2
|
||||
}
|
||||
```
|
||||
|
||||
Note that this module does not attempt to normalize relative z-index values,
|
||||
such as `-1`; indeed, it will abort immediately when encountering these values
|
||||
as it cannot be sure that rebasing mixed positive & negative values will keep
|
||||
the stacking context intact. Be careful with using this module alongside
|
||||
JavaScript injected CSS; ideally you should have already extracted all of your
|
||||
stacking context into CSS.
|
||||
|
||||
## API
|
||||
|
||||
### zindex([options])
|
||||
|
||||
#### options
|
||||
|
||||
##### startIndex
|
||||
|
||||
Type: `number`
|
||||
Default: `1`
|
||||
|
||||
Set this to any other positive integer if you want to override z-indices from
|
||||
other sources outside your control. For example if a third party widget has a
|
||||
maximum z-index of `99`, you can set this to `100` and not have to worry about
|
||||
stacking conflicts.
|
||||
|
||||
## Usage
|
||||
|
||||
See the [PostCSS documentation](https://github.com/postcss/postcss#usage) for
|
||||
examples for your environment.
|
||||
|
||||
## Contributing
|
||||
|
||||
Pull requests are welcome. If you add functionality, then please add unit tests
|
||||
to cover it.
