[POLL] Mark all the tags in HTML export with unique class (was: Adding a class to the auto-inserted <br> elements)

[Ihor Radchenko]

We are discussing the way Org formats HTML tags in HTML export.
Some of the tags added by Org are simply bare tags, like <br /> below.

<li><a id=".."></a>Low-level heading<br />

The suggestion is to add a unique class to each tag produced by Org HTML
export, so that CSS rules can precisely target various tags.

For example, Org can produce <br> tag in multiple contexts:

1. when exporting explicit line break \\
2. when exporting a heading as list item, to avoid merging the heading
   and its text
3. to separate title/subtitle
4. to separate inlinetask headline from its contents
etc...

We may export each <br> (or any other tag) as <br class="tag context">

Pros: Easier to write CSS selectors and possibly to post-process the
      generated HTML

Cons: HTML will become less readable

WDYT?

Ok. I see your motivation.
However, it does not make any sense to change _only_ one single specific
case where we insert <br> tag.
If we follow your argument, we should do it for every single tag that
ox-html inserts.

I am personally neutral to having such a change.
However, we discussed a somewhat similar proposal in the past wrt LaTeX
export and some users were concerned about reduced readability of the
produced .tex documents. See

So, I'd like to hear from other Org users first, because deciding
whether we want to add the feature you are asking for.
