Issue #699 Use term ZStack like in SwiftUI, we declare container as relative position. For now it uses only 2 items from props.children but can be tweaked to support mutiple class App extends React.Component { render() { return ( <ZStack> <Header /> <div css={css` padding-top: 50px; `}> <Showcase factory={factory} /> <Footer /> </div> </ZStack> ) } } /** @jsx jsx */ import React from 'react'; import { css, jsx } from '@emotion/core' export default function ZStack(props) { return ( <div css={css` position: relative; border: 1px solid red; `}> <div css={css` position: absolute; top: 0; left: 0; width: 100%; z-index: -1; `}> {props....

Issue #658 Declare routes, use exact to match exact path as finding route is from top to bottom. For dynamic route, I find that we need to use render and pass the props manually. Declare Router as the rooter with Header, Content and Footer. Inside Content there is the Switch, so header and footer stay the same across pages import { BrowserRouter as Router, Switch, Route, Link } from 'react-router-dom' function Content() { return ( <Switch> <Route exact path="/about"> <About /> </Route> <Route exact path="/"> <Home /> </Route> <Route path='/book/:id' render={(props) => { return ( <BookDetail {....
