How to create an HTTPS certificate for localhost domains

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).

React HOC (Higher Order Component) Example
/* HOC fundamentally is just a function that accepts a Component and returns a Component:
(component) => {return componentOnSteroids; } or just component => componentOnSteroids;
Let's assume we want to wrap our components in another component that is used for debugging purposes,
it just wraps them in a DIV with "debug class on it".
Below ComponentToDebug is a React component.
*/
//HOC using Class
//it's a function that accepts ComponentToDebug and implicitly returns a Class
let DebugComponent = ComponentToDebug => class extends Component {

A CSS pseudo-element is used to style specified parts of an element. In some cases you can style native HTML controls with vendor specific pseudo-elements. Here you will find an list of cross browser specific pseudo-element selectors.

Styling native elements

Native HTML controls are a challenge to style. You can style any element in the web platform that uses Shadow DOM with a pseudo element ::pseudo-element or the /deep/ path selector.
