@iamvery ♥ HTML

The Web Something I’m building Something you’re building

@iamvery ♥ Plain HTML

@iamvery ♥ <article> <h2>The Post Title</h2> <p> The post body.
</p> </article>

@iamvery ♥ %{ posts: [ %{title: "Interesting Facts”, body: "Cats
are soft. Dogs are noisy."}, %{title: "Bears", body: "Bears eat beets."}, ] }

@iamvery ♥ <%= for post <- @data.posts %> <article> <h2><%=
post.title %></h2> <p><%= post.body %></p> </article> <% end %>

@iamvery ♥ <article data-prop="posts"> <h2 data-prop="title"></h2> <p data-prop="body"></p> </article>

@iamvery ♥ <article data-prop="posts"> <h2 data-prop=“title">Interesting Facts</h2> <p data-prop=“body”> Cats
are soft. Dogs are noisy. </p> </article> <article data-prop="posts"> <h2 data-prop="title">Bears</h2> <p data-prop=“body”> Bears eat beets. </p> </article>

@iamvery ♥ Content

@iamvery ♥ The 5 Forms of Data

@iamvery ♥ 1. Properties are mapped

@iamvery ♥ %{property: “value”}

@iamvery ♥ 2. Tag content

@iamvery ♥ “value” %{property: }

@iamvery ♥ 3. Tag attributes

@iamvery ♥ [href: “http://…”]

@iamvery ♥ 4. Combined content

@iamvery ♥ {“Click”, href: “http://…”}

@iamvery ♥ 5. Iteration

@iamvery ♥ <%= for post <- @data.posts %> <article> <h2><%=
post.title %></h2> <p><%= post.body %></p> </article> <% end %>

@iamvery ♥ %{items: [“first”, “second”]}

@iamvery ♥ %{ active_user: %{name: "Jay"}, posts: [ %{ title:
"Cats Facts", body: "Some cats are fuzzy.", comments: ["I like cats.", "I prefer dogs."], edit_link: {"Edit 'Cat Facts'", href: "http://example.com/posts/1"}, }, %{ title: "Sleepy Dog", body: "Dogs sleep a lot.", comments: [], edit_link: {"Edit 'Sleepy Dog'", href: "http://example.com/posts/2"}, }, ], new_post: [disabled: true], }
