ITCSS components

Principios de los componentes

  • Aislamiento
  • Reusabilidad
  • Flexibilidad
  • Agnósticos de su contenido

Propiedades de los componentes

  • Colores y bordes
  • Tipografía y tamaño de fuente
  • Propiedades del modelo de caja de los elementos hijos

Variaciones de los componentes

  $avatar-size:       $global-spacing-unit * 3;
  $avatar-size-large: $avatar-size * 2;
  $avatar-size-small: $avatar-size / 2;

  .c-avatar {
    display: block;
    width:  $avatar-size;
    height: $avatar-size;
    border-radius: 100%;
  }

  .c-avatar--small {
    width:  $avatar-size-small;
    height: $avatar-size-small;
  }

  .c-avatar--large {
    width:  $avatar-size-large;
    height: $avatar-size-large;
  }

        <a href="#0" class="c-nav-primary__link  is-active">Top Discovries</a>
      <li class="o-list-inline__item">
        <a href="#0" class="c-nav-primary__link">Sign Out</a>
    </ul>
<main class="o-pack">

  <form class="o-pack__item c-site-search">
    <input class="c-site-search__field" type="text">
    <button class="c-site-search__btn">Submit</button>
  </form>

  <article class="o-pack__item c-post">
    <!-- ... -->
  </article>

</main>

Distribución de los componentes

Los elementos del componente, preferiblemente deben de ser distribuidos en los estilos del componente.


.c-nav-secondary {
  text-align: center;
}

  .c-nav-secondary__item {
    padding-right: $global-spacing-unit-small;
    padding-left:  $global-spacing-unit-small;
  }

    .c-nav-secondary__link {
      @include font-weight(normal);
    }

Distribución de los componentes

Si el componente es un elemento de otro componente padre puedes usar tal comportamiento para su distribución en ese contexto

<article class="c-post">

  <h1 class="c-post__title"></h1>
  <!-- ... -->

  <form class="c-post__search c-site-search">
    <input class="site-search__field" type="text">
    <button class="site-search__btn">Submit</button>
  </form>

</article>

    .c-post {}
    .c-post__title {}

    .c-post__search {
      float: right;
      max-width: 40%;
    }

ITCSS añadiendo capas

Una arquitectura flexible

Capa animación

Animaciones y transiciones reusables


    .a-lift-reveal {
      opacity: 0;
      transition: transform $s-timing--fast ease-out, opacity $s-timing--fast linear;
      transform: translate(0, -25%);

      &.in {
        opacity: 1;
        transform: translate(0, 0);
      }
    }

Capa scope

Un scope para controlarlos a todos


  .s-wysinwyg {
    h1, h2, h3, h4, h5, h6 {
      font-size: $s-core-font-size;
    }
    ul, ol {
      margin-left: $s-space;
    }
    br + br {
      display: none;
    }
    [style]:after {
      content: " ¡¡ Como me cambies el color te meto dos yoyas !!";
      color: red;
    }
  }

Capa shame

Pracmátismo desde el Craftsmanship


  // c-site-search__field
  // Bug PV-563 on IE <= 10

  ._c-site-search__field {
    margin-left: -2px;
    margin-right: -2px;
  }
