暂不考虑添加此设置参数。可以用自定义 CSS 修改。

This will not be worked on but we appreciate your contribution.

@stevenjoezhang 不好意思，我尝试自定义了一下 CSS ，好像不行，麻烦看一下我做得对不对，以下修改的部分我在浏览器控制台修改是成功的。

在 source/_data/styles.styl 中放入

@media{
	.back-to-top {
		right: 20px !important;
	}
}

.back-to-top {
	right: 30px !important;
}

在_config 中放入

custom_file_path:
  style: source/_data/styles.styl

@media 可以改成 @media (max-width: 991px) 试试。
