# Template Partials
Partials allow you to reuse code inside your template, instead of having redundant code scattered throughout your files. This can make your template easier to maintain.

## Creating a Partial
To create a partial add a .block file to your /blocks/ folder. This file can contain any kind of code used in template files, most commonly HTML and JSON-T.

To use a partial in a template add a JSON-T formatter with the block file name inside the tag, like the code example below demonstrates.

```html
{@|apply some-block.block}
```

## When Should I Use Partials?
Think of partials like classes in CSS. A class is typically something that is reused across your site; classes are also broad and can be used in analogous contexts. If you will use a piece of code in your template more than once in a similar setting you may want to consider making it a partial.

## Example
For the purpose of example, let's build a line of metadata that can be used in several different collections on both .list and .item pages.

```html
item-meta.block
----------------------------
<div class="item-meta">
      <p>Added on {addedOn|date %B %d, %Y} by {author.displayName}</p>
</div>
```

This partial can be rendered in either a .list or .item file in any collection type. The output changes depending on the context. For instance, we can render it in the following ways.

```html
blog.list:
----------------------------
{.repeated section items}
  {@|apply item-meta.block}
{.end}

blog.item:
----------------------------
{.section item}
  {@|apply item-meta.block}
{.end}

gallery.list:
----------------------------
{.repeated section items}
    {@|apply item-meta.block}
{.end}
```
**NOTE:** Partials are dependent on scope. If you break up your site into modules, it allows you to use them in several different contexts. To learn how scoping works visit [this page](http://jsont.squarespace.com/scoping-example/).
