Better Default Colour for Subtitles

[DarioS]

The default colour seems to be the same as the background, which makes the text appear to be invisible. For example, I have

title: "Classification for High-dimensional Biomedical Data"
subtitle: "Utilising ClassifyR"

to break the long title into two lines. But, the subtitle can only be seen if dragged across with the mouse cursor.

I also tried

title: |
       | Classification for High-dimensional Biomedical Data
       | Utilising ClassifyR

but the output was not as expected (colour and size of second line had changed).

As background, this was the cuplrit:

.remark-slide-content > h2:first-of-type {
  color: #e64626;
  margin-top: 5px;
  margin-bottom: 10px;
}

Which was done to make the h2 titles on each slide match powerpoint. But it also did it on the first slide, so I've used important! on the first slide (ugly css, I know).

.title-slide h2 {
  color: black !important; /* first of type is master brand red */
  font-size: 35px;
  padding-left: 20px;
  padding-bottom: 10px;
  margin-top: 0px;
  text-align: left;
  vertical-align: middle;
}

For your use case though, it's not really a subtitle, did you try using
to add a line break? @DarioS

I just did, fails big time, I wonder why!?! It's something I've done, because it's not a problem for standard xaringan.

Ah, a bad line-height: 0.05; setting.
