Template:Poem end
This template essentially duplicates the function of the tag <div class="lefttext"> by adding padding and a set width for the content of a page.
However, there are a few essential differences: it is meant for poetry and does not automatically indent, since it is a template it is easily tweakable (for any future changes), and it allows for variable widths.
It pairs with Template:Poem end, which is essentially just a </div> closing tag but should be used to allow for any future changes to the template that also affect the end tag.
It should also be used with the <poem> and </poem> tags (which cannot be included in this template, because they don't transclude properly).
