Angularjs is a front end library for create beautiful interactive web application using Nodejs ( JavaScript). If you are familiar with Reactjs , may catch it faster. The initial setup for Angularjs require the following
- NMP
- Nodejs
- VSCODE
- Angular CLI
- TypeScript
Angular used TypeScript, so better to learn some basics, almost everything in TS is same as JS does, with some changes. It is a superset of JS.
The Project Structure

With CLI command ng new <project-name> we can create Angular project on the top of Nodejs with above file structure
Binding style class
You have been noticed that every Angularjs component has a …component.css. This is where place all your SASS/CSS styling classes and ids. We can also use the inline style in your component.ts file, if you prefer ( as an array).
ngClass allow us to define and apply set of Styles and properties to a component.
Define Object and property
In class definition declare property with class.
public isClicked = true; public btnSpecial = { "btn": !this.isClicked, "btn-clicked": this.isClicked, "btn- special": this.isClicked };
Define CSS
In your app component.css file define a simple button class
.btn{ background-color:rgba(51, 134, 243, 0.986); margin: 5px; padding: 4px; color: white; border: 1px; border-radius: 2px; } .btn-clicked { background-color: rgba(243, 153, 51, 0.986); border-color: rgb(255, 0, 0); } .btn-special{ border-style: double; border-block-start-color: aquamarine; }
Bind
It is possible bind the style object we created to accommodate multiple style, using the ngClass as follows
<button [ngClass]="btnSpecial">OK</button>
Class binding has higher precedence in Angular, that means when we use the both methods only the binding will work. So both can’t be used.
I know the above example is minimal , you can experiment much more , first I suggest have a clear understanding about CSS. A project based tutorial may help you[You Tube/Udemy].
