<h2>CSS Layout Float</h2>
<p>In this example, we have created a header, two columns/boxes and a footer. On smaller screens, the columns will stack on top of each other.</p>
<p>Resize the browser window to see the responsive effect (you will learn more about this in our next chapter - HTML Responsive.)</p>

Layout de flutuador CSS
É comum fazer layouts da Web inteiros usando a float propriedade CSS . O float é fácil de aprender – você só precisa se lembrar de como as propriedades floate clear funcionam.
Desvantagens: Os elementos flutuantes estão vinculados ao fluxo do documento, o que pode prejudicar a flexibilidade.

Layout do CSS Flexbox
Flexbox é um novo modo de layout no CSS3.
O uso do flexbox garante que os elementos se comportem de maneira previsível quando o layout da página deve acomodar diferentes tamanhos de tela e diferentes dispositivos de exibição.
