Greetings.
The following explanation is a bit long, so here is a summary:
1. "pre.src" formatting no longer seems to work in html export
2. "pre code" works, but incorrectly from my point of view.
I am looking for a fix.
Here is the longer explanation
1. pre.src does not work
------------------------
I used to have a working CSS file for some programming teaching material
exported from Org. Something has changed, because earlier formatting
used pre.src in the following style:
pre.src
{
margin: 0 auto;
font-size: 0.9vw;
width: 75em;
color: white;
background-color: #102e4e;
border-radius: 10px;
}
In particular, background-color controlled the background of the entire
source block "window" in the exported html.
According to the manual, pre.src still controls formatting for source
code blocks:
http://orgmode.org/manual/CSS-support.html
However, when I export the same files right now, pre.src no longer
works. The change in the exported html files is obvious:
old export (pre.src worked)
<pre class="src src-processing"> ...
new export (pre.src no longer works)
<pre><code class="src src-processing"> ...
2. "pre code" works incorrectly (from my point of view)
-------------------------------------------------------
I can get my CSS file to do _something_ with the following change:
pre code
{
margin: 0 auto;
font-size: 0.9vw;
width: 75em;
color: white;
background-color: #102e4e;
border-radius: 10px;
}
However, the problem is that this changes only the background of the
code text, not the entire "window". The effect can be seen here:
old export (code blocks colored correctly):

new export (code blocks colored incorrectly);

How do I fix this? Thanks!

Did some further studies. It turns out that in this particular case I
can get the blocks to color correctly by coloring just pre:
pre
{
margin: 0 auto;
font-size: 0.9vw;
width: 75em;
color: white;
background-color: #102e4e;
border-radius: 10px;
}
But I can't be expected to color all preformatted text similarly. Right?
There has to be a way to format the code windows only.
(Unfortunately there is no parent selector in CSS. Otherwise I could
select the pre that have a code descendant.)

Greetings again.
Due to the flurry of responses to this thread (like, zero), I will make
a suggestion:
Could we reinstate pre.src by including the src class into pre tags as
well? That is, whereas we now have in the new export
<pre><code class="src...
we would have, sort of like in the old export
<pre class="src"><code class="src...
This would solve my issues. Would it be ok?

I hear the faint sound of a bell somewhere. Is it related to
`org-html-keep-old-src' variable and commit
d5bbf365533ba45d72ebed8121c7612c860ea944?
IIRC, there were some issues with klipse support implementation.
I cannot remember if those were solved. You might find more information
browsing the mailing list archives.
