.field {
margin-bottom: 1rem;
}<div class="field field--name-field-frequency field--type-entity-reference field--label-above">
<div class="field__label">
Frequency
</div>
<div class="field__item">
Daily
</div>
</div>Fields have a label that can be hidden, above, or inline.
Fences
The Fences module lets you configure field and wrapper tags and classes for a low-code workflow.
To support fences, it's field.html.twig is used in the theme.
The template only works with fences installed, so it is required.
TODO: Use template only if fences is enabled. Consider making a field component that can be inherited in other templates.
