ioslides markdown演示文稿标题页中的字体大小

问题描述

尝试从ioslides演示文稿更改标题页的默认文本大小，但失败:

Trying to alter the default text size of the title page from an ioslides presentation but failing:

---
title: "My title is a bit too long to fully fit on the title page. I would really like to alter the font size to  provide a better fit. I have limited CSS skills to do so"
author: "My Name"
date: "29 March 2016"
output:
  ioslides_presentation:
  css: slide.css
---

## R Markdown

This is an R Markdown presentation.

我的style.css文件在哪里:

Where my style.css file is:

h1 { font-size: 12px;}

推荐答案

首先，在YAML中，空格/缩进/制表符很重要(请注意css行上的其他选项卡):

First, spacing/indentation/tab is important in YAML (notice the additional tab on the css line):

output:
  ioslides_presentation:
    css: slide.css

这不是完美的，希望其他人也可以加入，但是您可以使用hgroup和h1标签通过以下方式调整.title-slide类:

This is not perfect and hopefully somebody else can chime in, but you can adjust .title-slide class with hgroup and h1 tags with:

.title-slide hgroup h1 {
  font-size: 12px;
  letter-spacing: 0;
}

注意:在当前示例中，您需要将letter-spacing修改为0(与原始渲染的3px相对).

Note: You will want to modify letter-spacing to 0 (as opposed to the original rendered 3px) in the current example.
