Movie Card

Movie card screenshot

The Movie Card component is a more advanced component compared to the ones we've built thus far. Here we will start reusing previously built components by using twig's Include and Embed statements.

By now you should know the drill, inside src/_patterns/01-patterns/ create a new directory (which matches the name of the component), and inside that directory add some files.

Component Data

  1. Inside nitflex_dev_theme/src/_patterns/01-patterns/ create a new directory called movie-card

  2. Inside the movie-card directory create a new file called movie-card.yml.

  3. Inside movie-card.yml add the following code:

cover_image: "<img src=\"/sites/default/files/action-3.jpg\" alt=\"Alt text\" />"
heading:
title: "I love this movie"
url: "#"
heading_level: 4
modifier: "movie-card__heading"
average_rating: "3"
mpaa_rating: "PG-13"
synopsis: "Aenean lacinia bibendum nulla sed consectetur. Maecenas sed diam eget risus varius blandit sit amet non magna."

By looking at the prototype we see that the landing page shows a listing of movies. Given the hierarchy of content we see the page already has a h1 and h2 in the featured movie section. Each movie category also uses a heading which will be h3, so using a h4 as the heading_level for the title of the movie in the card makes sense.

Component's markup

  1. Inside the movie-card directory create a new file called movie-card.twig.

  2. Add the following code:

<article class="movie-card
{{- attributes ? ' ' ~ attributes.class -}}"
{{- attributes ? attributes|without(class) -}}>
{{ title_prefix }}
{{ title_suffix }}
{% if cover_image %}
<div class="movie-card__cover-image">
{{ cover_image }}
</div>
{% endif %}
<div class="movie-card__content">
{% if heading %}
{%
include '@patterns/heading/heading.twig' with {
heading: heading
} only
%}
{% endif %}
<div class="movie-card__favorites-toggle">
{% block favorites_toggle %}
{%
include '@patterns/add-to-favorites/add-to-favorites.twig' with {
url: '#',
} only
%}
{% endblock %}
</div>
{% if mpaa_rating %}
<div class="movie-card__mpaa-rating">
{% include '@patterns/mpaa-rating/mpaa-rating.twig' with {
rating: mpaa_rating
} only
%}
</div>
{% endif %}
{% if average_rating %}
<div class="movie-card__average-rating">
{% include '@patterns/average-rating/average-rating.twig' with {
count: average_rating
} only
%}
</div>
{% endif %}
{% if synopsis %}
<div class="movie-card__synopsis">
{{ synopsis }}
</div>
{% endif %}
</div>
</article>
  • Notice we are using include statements to nest existing components into the movie-card. This is a simple example of how we can reuse previously built components.

  • The image and rest of content has been split into different containers (movie-card__cover-image & movie-card__content). This is always a good practice as it provides flexibility to move multiple content fields around at once should we have the need to do so.

  • Also notice we are reusing the heading component and simply changing its heading level and applying a unique class when inside the movie card. This provides context and allows us to style this heading independently of other headings in the page.

  • Finally, we are introducing the concept of Twig Blocks, (not the same as Drupal blocks), to provide a way to change how content is rendered when we integrate this component with Drupal. More on how Twig Blocks give us more flexibility at time of rendering content later.

Component Styles

  1. Inside the movie-card directory create a new file called movie-card.scss.

  2. Inside movie-card.scss add the following code:

// Import site utilities
@import '../../00-global/utils/init';
.movie-card {
background: $color-black;
color: $color-white;
height: 250px;
max-width: 420px;
overflow: hidden;
position: relative;
transition: transform 1s ease-in-out;
a {

}
// By defalt image overlay is not visible until
// hover is active.
&::after {

content: '';
display: block;

}
&:hover,

.movie-card__cover-image img {

}
// Dark overlay.
&::after {

}
// On hover the text content fades into view.
.movie-card__content {

}
}
}
.movie-card__cover-image {

}
.movie-card__heading {

}
.movie-card__favorites-toggle,

}
.movie-card__mpaa-rating {

.movie-card__average-rating {

}
.movie-card__synopsis {

@include breakpoint($bp-sm) {

}
.movie-card__content {
@include vertical-align(absolute);

flex-wrap: wrap;
font-size: 14px;
font-weight: 300;

transition: margin 0.5s ease 0.125s, opacity 0.5s ease 0.25s;
overflow: hidden;

z-index: 2;
}

Quite the styles huh? 😄

Compiling the code

Let's take a look at the Movie Card component by compiling our code and building the style-guide.

  • In your command line, navigate to /themes/custom/nitflex_dev_theme.

  • Run this command:

lando npm run build && lando php patternlab/core/console --generate

Working with Drupal Libraries

Let's take a break from building components for a moment to learn about Drupal Libraries. Drupal libraries is how we add CSS and Javascript to content in Drupal. Proceed to Drupal Libraries.
