Angular CLI

Angular CLI

Angular now has its own CLI, or command line interface, which will do most of the routine operations for you. To start using Angular, we have to install it. It requires Node 6.9.0 or higher as well as NPM 3 or higher. We are not going to cover their installation for your system, as it’s better to find up-to-date documentation for installation on your own. Once they are both installed, we are going to install Angular CLI by running the following:

npm install -g @angular/cli

This command use for install angular cli. This command run in terminal.

ng serve

This command use for run program. 

RGB (Red, Green, Blue)

Css Color

Colors in CSS are most often specified by:

• a valid color name - like "red"
• an RGB value - like "rgb(255, 0, 0)"
• a HEX value - like "#ff0000"

Note: Color names are case-insensitive: "Red" is the same as "red" or "RED".

RGB (Red, Green, Blue)

RGB color values can be specified using this formula: rgb(red, green, blue).

Each parameter (red, green, blue) defines the intensity of the color between 0 and 255.

For example, rgb(255,0,0) is displayed as red, because red is set to its highest value (255) and the others are set to 0. Experiment by mixing the RGB values

Hexadecimal Colors

RGB values can also be specified using hexadecimal color values in the form: #RRGGBB, where RR (red), GG (green) and BB (blue) are hexadecimal values between 00 and FF

(same as decimal 0-255).

For example, #FF0000 is displayed as red, because red is set to its highest value (FF) and the others are set to the lowest value (00). 

Note: HEX values are case-insensitive: "#ff0000" is the same as "FF0000".
this is very important for css because color are use in css many times.
therefore read this chapter two three time for making color schemes ................

jquery

JQUERY

jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML. jQuery is the most popular JavaScript library in use today, with installation on 65% of the top 10 million highest-trafficked sites on the Web. jQuery is free, open-source software licensed under the MIT License.

jQuery's syntax is designed to make it easier to navigate a document, select DOM elements, create animations, handle events, and develop Ajax applications. jQuery also provides capabilities for developers to create plug-ins on top of the JavaScript library. This enables developers to create abstractions for low-level interaction and animation, advanced effects and high-level, themeable widgets. The modular approach to the jQuery library allows the creation of powerful dynamic web pages and Web applications.

The set of jQuery core features—DOM element selections, traversal and manipulation—enabled by its selector engine(named "Sizzle" from v1.3), created a new "programming style", fusing algorithms and DOM data structures. This style influenced the architecture of other JavaScript frameworks like YUI v3 and Dojo, later stimulating the creation of the standard Selectors API.

Microsoft and Nokia bundle jQuery on their platforms. Microsoft includes it with Visual Studio for use within Microsoft's ASP.NET AJAX and ASP.NET MVC frameworks while Nokia has integrated it into the Web Run-Time widget development platform. jQuery has also been used in MediaWiki since version 1.16.
