## Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

### Prerequisites

To install this Language Server you need [npm](https://www.npmjs.com/get-npm) on your machine

npm install --global vscode-css-languageserver-bin

## Settings

```typescript
type Level = "ignore" | "error" | "warning"

type LintSettings = {
	// From: https://github.com/Microsoft/vscode-css-languageservice/blob/master/src/services/lintRules.ts#L25

compatibleVendorPrefixes?: Level, // When using a vendor-specific prefix make sure to also include all other vendor-specific properties. Default: Ignore
	vendorPrefix?: Level, // When using a vendor-specific prefix also include the standard property. Default: Warning
	duplicateProperties?: Level, //, localize('rule.duplicateDeclarations', "Do not use duplicate style definitions. Default: Ignore
	emptyRules?: Level, // Do not use empty rulesets. Default: Warning
	importStatement?: Level, // Import statements do not load in parallel. Default: Ignore
	boxModel?: Level, // Do not use width or height when using padding or border. Default: Ignore
	universalSelector?: Level, // The universal selector (*) is known to be slow. Default: Ignore
	zeroUnits?: Level, // No unit for zero needed. Default: Ignore
	fontFaceProperties?: Level, // @font-face rule must define 'src' and 'font-family' properties. Default: Warning
	hexColorLength?: Level, // Hex colors must consist of three, four, six or eight hex numbers. Default: Error
	argumentsInColorFunction?: Level, // Invalid number of parameters. Default: Error

	float?: Level, // Avoid using 'float'. Floats lead to fragile CSS that is easy to break if one aspect of the layout changes. Default: Ignore
	idSelector?: Level // Selectors should not contain IDs because these rules are too tightly coupled with the HTML. Default: Ignore
