我（一个新手）正在编辑一个诗歌博客。诗歌有着奇怪的间距，我无法得到任何代码组合来满足我的需要。例如，一首诗需要单行间距，但它也需要在特定行上进行缩进。
示例：
This is the first line of the poem,
then the next line is spaced the same.
But this line needs to be indented.
And then the next line goes back again.
同样，另一首诗也有交替的缩进线条。
示例：
The first line is intented,
But then the next line is fully left-aligned.
Then this line again is indented,
But the one following is fully aligned again.
