<div class="field">
<div class="control">
<%= f.input :title, input_html: { class: 'input' }, wrapper: false, label_html: { class: 'label' } %>
</div>
</div>    
<div class="field">
<div class="control">
<%= f.input :content, input_html: { class: 'textarea' }, wrapper: false, label_html: { class: 'label' }  %>

<div>
<%= f.label :image %>
<%= f.file_field :image %>
</div>    
<%= f.button :submit, 'Create new post', class: "button is-primary" %>
<% end %>
