Ngx Simple Spinner
Simple and lightweight, yet customizable spinner/number input module for Angular.
This is a number input component for Angular, fully supporting template driven forms and form validation. It is completely customizable using SCSS/CSS. Additionally it features: displaying most common fractions (1/2, 1/3, 1/4, ...), setting decimal places, i18n and RTL (right-to-left). It replicates Google Chrome's behaviour regarding its base functionality.

Styling
You can use SCSS or CSS for styling.
Just import the stylesheet and apply changes to it.
The SCSS stylesheet is recommended since it exports more variables.
If you are not using SCSS for your Angular projects already, you really should.
CSS / SASS
@import '~@nutrify/ngx-simple-spinner/scss/styles';Angular
angular-cli.json:
"styles": [
"styles.css",
"../node_modules/@nutrify/ngx-simple-spinner/css/styles.css"
