CssVar

CssVar is a node module used to manage CSS variables dynamically using JavaScript. This module allows to log, get and set CSS variables. CssVar is capable of doing each operation withing a particular scope of CSS variables.

Installation

npm install @thadathilsinan/cssvar

Initialization

First of all you have to import the module

import CssVar from "@thadathilsinan/cssvar";

After that we can initialize the module with a particular variable scope.

NOTE : CSS variables are scoped using the CSS selectors. The global scope is referred as the selector ":root". We can have any local scope such as our class selectors, id selectors, etc.

let cssVar = new CssVar("selector"); //For global scope use :root as selector

Usage

The primary operations we can do with this module are:

• Log variables
• Set value for variable
• Get value of a variable

log()

This method call will log all the variables into the console.

cssVar.log();

log(selector)

This method call will log all the variables in a particular scope into the console.

cssVar.log(":root"); //Log all global variables

NOTE: Normally CSS variable name start with "- -". But you have to remove the prefix when using with get(), set() methods. Example variable declaration: - -my-var-name: 10px; We can use this variable by removing "- -", that is "my-var-name"

get(variablename)

To return the value of a particular variable in any scope (global/local)

cssVar.get("my-var-name");

get(variablename, selector)

To return the value of a particular variable in a particular scope

cssVar.get("my-var-name", "#my-container-div-id");

set(variablename)

To erase the current value of a particular variable in any scope by setting it as empty string

cssVar.set("my-var-name");

set(variablename, newValue)

To set a particular variable in any scope with a new value

cssVar.set("my-var-name", "100px");

set(variablename, newValue, selector)

To set a particular variable in a given scope with a new value

cssVar.set("my-var-name", "100px", ".my-class-name");
