Slidify：如何在 Title Slide 中将 YAML 文本定位到右侧？

Question

我正在修改幻灯片的第一张幻灯片。

我可以使用图像作为背景，但是我无法将 "yalm text: title, subtitle, and author" 放在幻灯片的右侧（它与我的图像背景冲突）。

我试过修改名为 "slidify" 的 CSS，就像我对背景所做的那样。

但是我没有得到预期的结果，相反所有的文字都在左下角被压碎了：

HTML 部分：

<!-- LOGO SLIDE -->
        <slide class="title-slide segue nobackground">
  <hgroup class="auto-fadein">
    <h1>Tottus</h1>
    <h2>Apertura Molicentro</h2>
    <p>author<br/></p>
  </hgroup>
  <article></article>  
</slide>

CSS 部分：

.title-slide {
  background-color: #FFFFFF; /* #EDE0CF; ; #CA9F9D*/
  /*background-image:url(D:\presentaciones\star-bg.png); */
  background-repeat: no-repeat;
  background-position: center center;
  background-size: contain; 
  position:relative;  

  /* background-image:url(http://goo.gl/EpXln); */
}



.title-slide hgroup > h1, 
.title-slide hgroup > h2 {
  color: black ;  /* ; #EF5150*/
  position:absolute;
  right: 0;
}

更新 1：

感谢@LGSon，我取得了一些进步。参见：

问题：

1.- 我使用 .title-slide hgroup 仅影响标题幻灯片上的 hgroup，并在其上使用背景灰色。但是文字全乱了。

2.- 使用_top:300时，有块遮住文字。见第二张图片。

Answer 1

更新

这里的主要问题是，当一个人使用 position: absolute 时，需要在每个项目上设置一个唯一的位置，否则它们最终会相互重叠。

另一种方法是在 hgroup 上设置 position: absolute 并让 h1、h2 和 p 在其中正常流动。

html, body { margin: 0; height: 100%; }    /* needed in my demo, should not be needed in yours  */


.title-slide {
  background-color: white;
  /*background-image:url(D:\presentaciones\star-bg.png); */
  background-repeat: no-repeat;
  background-position: center center;
  background-size: contain; 
  position: relative;
}

.title-slide hgroup {
  position: absolute;
  width: auto;
  height: auto;
  right: 10px;
  bottom: 10px;
}

.title-slide hgroup > h1, 
.title-slide hgroup > h2,
.title-slide hgroup > p {
  margin: 0;
  color: black;
  text-align: right;
}
