CSS Handles e o poder da customização de blocos

:sparkles: Branch: csshandles

Introdução

Dando uma rápida olhada na sua loja atual, você conseguirá perceber que todos os componentes possuem estilos parecidos, mesmo que nenhuma customização tenha sido feita por você.

Todos eles, incluindo o Info Card recém configurado, compartilham valores pré-estabelecidos para fonte, cor de fundo, cor principal, formato dos botões, etc.

Isso se deve ao style.json, arquivo responsável por declarar valores genéricos de customização para toda loja do Store Framework.

style

Para criar uma identidade própria para os componentes da sua loja, você pode sobrescrever esses valores por meio de customizações de CSS.

Analisando a recipe para customizações de loja por CSS, percebemos que alguns passos serão necessários para aplicar o estilo próprio desejado por você, como:

  1. Criar um novo arquivo dentro da pasta CSS com o nome vtex.{AppName}.css

  2. Usar o CSS Handle do componente que será customizado dentro deste arquivo seguindo o formato abaixo:

    .{CSSHandle} {
    {PropriedadeDeCSS}: {ValorDesejado};
    {PropriedadeDeCSS}: {ValorDesejado};
}

  3. Na falta de CSS Handles, aplicar CSS Selectors permitidos, como é o caso do :global(vtex-{componentName}).

  4. Para aplicar CSS em um bloco específico e não a todos os blocos daquele tipo, usa-se o recurso de blockClass, que aparece ao lado dos handles de css ao inspecionar seu código. As blockClass devem ser declaradas como uma prop no bloco em questão, e então referenciado no arquivo de estilo como mostrado abaixo:

    .{CSSHandle}--{blockClass} {
    {PropriedadeDeCSS}: {ValorDesejado};
    {PropriedadeDeCSS}: {ValorDesejado};
}

Customizando o Info Card

Para descobrir os CSS Handles de um componente, como o Info Card, basta acessar a sessão Customization da sua documentação.

De acordo com a descrição dos CSS Handles e com a recipe customizações de loja por CSS, conseguimos implementar um exemplo de Info Card customizado, alterando seu título e as configurações do botão call to action ao adicionar o código a seguir no arquivo vtex.store-components.css dentro de /styles/css:

.infoCardHeadline {
    font-family: serif;
    font-size: 2.25rem;
    font-weight: normal;
    color: gray;
    border: 2px solid black;
    padding: 24px;
}

.infoCardCallActionContainer :global(.vtex-button) {
    color: white;
    background-color: gray;
    border: transparent;
}

.infoCardCallActionContainer :global(.vtex-button):hover {
    color: gray;
    background-color: blue;
    border: transparent;
}

Você pode conferir o efeito das mudanças feitas por você executando o comando vtex link.

Em seguida, vamos adicionar um estilo específico para o infocard Vintage. Para começar, adicione a prop blockClass no info-card#button-right como mostrado abaixo:

"info-card#button-right": {
  "props": {
    "isFullModeStyle": false,
    "textPosition": "right",
    "imageUrl": "https://appliancetheme.vteximg.com.br/arquivos/cozinha-rosa-min.png",
    "headline": "Vintage Pink",
    "subhead": "Give your kitchen a boho style adding vintage apparels.<br>Available until January 2020.",
    "callToActionMode": "button",
    "callToActionText": "Explore",
    "callToActionUrl": "/sale/d",
    "textAlignment": "center",
    "blockClass": "vintage"     //  <------------
  }
}

E então declare uma background-color para este infocard específico no seu arquivo de css:

.infoCardContainer--vintage {
  background-color: #edcfd1
}

Observe o efeito atingido linkando sua app.

Atividade

  1. No arquivo vtex.store-components.css, copie o código acima para usá-lo no arquivo CSS do seu tema, seguindo a recipe sobre customizações de loja por CSS;
  2. Com base nos Handles do Info Card, defina a largura máxima (max-width) de de todos os infocards para 1260px, a margin para 0 auto e o padding para 0.
  3. Mude a cor do título do componente para black;
  4. Coloque o título em negrito (bold);
  5. Mude a cor de fundo do botão durante o hover para white.
  6. Paralelamente ao blockClass vintage, aplique um novo block class chamado metal no infocard info-card#button-left e aplique a cor de fundo #e1e1e1nele.
