Google AMP - Layout

Layout AMP é um dos recursos importantes disponíveis no Google-amp. O layout do amplificador garante que os componentes do amplificador sejam renderizados corretamente quando a página é carregada, sem causar oscilações ou problemas de rolagem. O Google AMP garante que a renderização do layout seja feita na página antes de qualquer outro recurso remoto, como solicitação de imagens http, e chamadas de dados.

A lista de atributos de layout é fornecida abaixo.

  • largura e altura

  • layout

  • sizes

  • heights

  • media

  • placeholder

  • fallback

  • noloading

Vamos considerar o layoutatributo em detalhes neste capítulo. Os demais atributos são discutidos em detalhes no capítulo -Google AMP – Attributes deste tutorial.

Atributo de layout

Podemos usar o atributo layout em um componente amp, que decidirá como o componente será renderizado dentro da página. Uma lista de layouts suportados pelo amplificador é fornecida abaixo -

  • Não presente

  • Container

  • fill

  • fixed

  • fixed-height

  • flex-item

  • intrinsic

  • nodisplay

  • Responsive

Para cada um desse layout, veremos um exemplo prático que mostrará como o atributo layout renderiza o componente amp de maneira diferente. Faremos uso deamp-img componente em nossos exemplos.

Exemplo de altura fixa e altura fixa

Antes de entender o uso de altura fixa e altura fixa, observe os dois pontos a seguir -

  • layout=”fixed” precisa ter largura e altura e o componente do amplificador será mostrado nisso.

  • layout=”fixed-height” precisa ter a altura especificada para o componente. Isso garantirá que a altura não seja alterada. A largura não deve ser especificada ao usar altura fixa ou pode ser automática.

nodisplay e responsivo

O componente Amp com layout = nodisplay não ocupará nenhum espaço na página, assim como display: none. Não há necessidade de adicionar nenhuma propriedade de largura e altura a esse layout.

O componente Amp com layout = responsive ocupará o espaço disponível ou a largura da página e a altura será redimensionada mantendo a proporção do elemento.

Amp- Acordeão

Amp-acordeão é um componente de amplificador usado para exibir o conteúdo no formato expandir-recolher. Torna-se fácil para os usuários visualizá-lo em dispositivos móveis, onde podem selecionar a seção de acordo com sua escolha no acordeão.

Para trabalhar com amp-Accordion, você precisa adicionar o seguinte script -

<script async custom-element = "amp-accordion" 
   src = "https://cdn.ampproject.org/v0/amp-accordion-0.1.js">
</script>

Etiqueta Amp-acordeão

<amp-accordion>
   <section class = "seca">
      <h3>Content 1</h3>
      <div>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>
         <p>Content 1 is opened for amp-accordion</p>

         <p>Content 1 is opened for amp-accordion</p>

Resultado

O amplificador acordeão tem seções dentro dele. Cada seção pode ter 2 filhos e mais de 2 exibirão um erro no console do navegador. Você pode adicionar um contêiner na seção e pode ter vários elementos nele.

Por padrão, mantivemos uma seção em modo expandido usando o atributo expandido para a seção.

Acordeões de recolhimento automático

Para recolhimento automático, estamos usando o atributo expand-single-section no amplificador-acordeão, conforme mostrado no exemplo. A seção que o usuário abre permanecerá apenas em repouso expandido, os outros fecharão usando expand-single-section atributo.

Carrossel AMP

Amp-carrossel é um componente de amplificador para mostrar um conjunto de conteúdos semelhantes na tela e usar as setas para alternar entre os conteúdos.

Para trabalhar com amp-carousel, precisamos adicionar o seguinte script -

<script async custom-element = "amp-carousel" src = "https://cdn.ampproject.org/v0/amp-carousel-0.1.js"></script>

Tag Amp-carrossel

A tag amp-carousel é mostrada abaixo -

<amp-carousel height="300" layout="fixed-height" type="carousel">
      <amp-img src="images/christmas1.jpg" width="400" height="300" alt="a sample image"></amp-img>
   ….
</amp-carousel>

Atributos disponíveis para amp-carrossel

Os atributos disponíveis para amp-carousel estão listados na tabela mostrada abaixo -

Sr. Não Atributo e descrição
1 type

Podemos exibir itens do carrossel como carrossel e slides
2 height

Altura do carrossel em pixels
3 controls (optional)

Ele exibe a seta para a esquerda / direita na tela.IT desaparece após alguns segundos nos dispositivos. Os CSS podem ser usados ​​para tornar as setas visíveis o tempo todo.
4 data-next-button-aria-label (optional)

Use para definir o rótulo do próximo carrossel.
5 data-prev-button-aria-label (optional)

Use para definir o rótulo do carrossel anterior.
6 autoplay (optional)

Use para mostrar o próximo slide após 5.000 ms. IT pode sobrescrever usando o atributo de atraso sem nenhum milissegundo no amp-carousel. Ele adicionará o atributo de loop ao carrossel e os slides serão reproduzidos novamente quando chegar ao fim. Usado apenas para type = slides e precisa de pelo menos 2 slides para que a reprodução automática funcione.

Agora, vamos trabalhar em exemplos para exibir carrosséis de maneiras diferentes.

Amp Image Slider

Amp-image-slider é um componente de amplificador usado para comparar duas imagens, adicionando o controle deslizante ao movê-lo verticalmente sobre a imagem.

Para trabalhar com amp-img-slider, adicione o seguinte script -

<script async custom-element = "amp-image-slider" src = "
   https://cdn.ampproject.org/v0/amp-image-slider-0.1.js">
</script>

Tag Amp-img-slider

<amp-image-slider width = "300" height = "200" layout = "responsive">
   <amp-img src = "images/christmas1.jpg" layout = "fill">
   </amp-img>
   <amp-img src = "images/christmas2.jpg" layout = "fill">
   </amp-img>
</amp-image-slider>

Um exemplo de amp-img-slider é mostrado aqui. Aqui nós adicionamos 2 imagens dentro do amp-img-slider, onde a primeira imagem funciona como um controle deslizante e você pode deslizar na parte superior da segunda imagem.
