In this article, we will learn about the Light Theme Style Variables offered by the blueprint.js library. BlueprintJS is a React-based UI toolkit for the web. It is written in Typescript. This library is very optimized and popular for building interfaces that are complex and data-dense for desktop applications that run in a modern web browser.
Light Theme Style Variables: These variables are used to build custom UI components that should look similar to Light-themed BlueprintJS components.
Light Theme Style Variables:
- $pt-dialog-box-shadow: It corresponds to the following value in CSS.
$pt-dialog-box-shadow:
0 0 0 1px rgba(17, 20, 24, 0.1),
0 2px 4px rgba(17, 20, 24, 0.2),
0 8px 24px rgba(17, 20, 24, 0.2)
- $pt-input-box-shadow: It corresponds to the following value in CSS.
$pt-input-box-shadow:
inset 0 0 0 1px rgba(17, 20, 24, 0.2),
inset 0 1px 1px rgba(17, 20, 24, 0.5)
- $pt-popover-box-shadow: It corresponds to the following value in CSS.
$pt-popover-box-shadow:
0 0 0 1px rgba(17, 20, 24, 0.1),
0 2px 4px rgba(17, 20, 24, 0.2),
0 8px 24px rgba(17, 20, 24, 0.2)
- $pt-tooltip-box-shadow: It corresponds to the following value in CSS.
$pt-tooltip-box-shadow:
0 0 0 1px rgba(17, 20, 24, 0.1),
0 2px 4px rgba(17, 20, 24, 0.2),
0 8px 24px rgba(17, 20, 24, 0.2)
Creating React Application And Installing Module
Step 1: Create a React application using the following command:
npx create-react-app foldername
Step 2: After creating your project folder i.e. foldername, move to it using the following command:
cd foldername
Step 3: After creating the ReactJS application, Install the required module using the following command:
npm install @blueprintjs/core npm install sass
Project Structure: It will look like the following.
Example 1: The below example demonstrates the usage of different Light Theme Style Variables used by BlueprintJS. Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
Filename: App.js
Javascript
import './App.scss'import "@blueprintjs/core/lib/css/blueprint.css"; export default function App() { return ( <div> <div className="head" style={{ width: "fit-content", margin: "auto", }} > <h1 style={{ color: "green", }} > neveropen </h1> <strong> React blueprint Light Theme Style Variables: </strong> <br /> <br /> </div> <div className="container"> <div className="box box-1"></div> <div className="box box-2"></div> <div className="box box-3"></div> <div className="box box-4"></div> </div> </div> ); } |
Create a new file, App.scss, and assign different Light-themed style variables to different boxes.
Filename: App.scss
CSS
@import "@blueprintjs/core/lib/scss/variables"; .container { display: flex; margin: 0 auto; justify-content: center; gap: 5px; } .box { width: 100px; height: 100px; background-color: white; } .box-1 { box-shadow: $pt-dialog-box-shadow; } .box-2 { box-shadow: $pt-input-box-shadow; } .box-3 { box-shadow: $pt-popover-box-shadow; } .box-4 { box-shadow: $pt-tooltip-box-shadow; } |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
Example 2: The below example demonstrates the usage of different Light-themed style variables with different shapes of boxes.
Filename: App.js
Javascript
import './App.scss'import "@blueprintjs/core/lib/css/blueprint.css"; export default function App() { return ( <div> <div className="head" style={{ width: "fit-content", margin: "auto", }} > <h1 style={{ color: "green", }} > neveropen </h1> <strong> React blueprint Light Theme Style Variables: </strong> <br /> <br /> </div> <div className="container"> <div className="box box-1"></div> <div className="box box-2"></div> <div className="box box-3"></div> <div className="box box-4"></div> </div> </div> ); } |
Create a new file, App.scss, and assign different Light-themed style variables to different-shaped boxes.
Filename: App.scss
CSS
@import "@blueprintjs/core/lib/scss/variables"; .container { display: flex; margin: 0 auto; justify-content: center; gap: 10px; } .box-1 { width: 100px; height: 100px; background: red; box-shadow: $pt-dialog-box-shadow; } .box-2 { width: 100px; height: 100px; border-radius: 50%; background: red; box-shadow: $pt-input-box-shadow; } .box-3 { width: 0; height: 0; border-left: 50px solid transparent; border-right: 50px solid transparent; border-bottom: 100px solid red; box-shadow: $pt-popover-box-shadow; } .box-4 { width: 100px; height: 100px; border-radius: 100px / 50%; background: red; box-shadow: $pt-tooltip-box-shadow; } |
Step to Run Application: Run the application using the following command from the root directory of the project:
npm start
Output:
