I type in Normal view

I go into HTML source and see this

I go back to Normal view and I see this

And that's what I see in Book Details

I thought I had 'fixed' this by tweaking L&F Book Details->Text styling

body, td { background-color: transparent;
body.horizontal table td.title { white-space: nowrap }
p { margin: 0}
a { text-decoration: none;
.comments { margin-top: 0; padding-top: 0; text-indent: 0
.comments-heading { font-size: larger; font-weight: bold
table.fields { margin-bottom: 0; padding-bottom: 0;
table.fields td { vertical-align: top
table.fields td.title { font-weight: bold
.series_name { font-style: italic
The HTML that this stylesheet applies to looks like this:
<h3 class="comments-heading">Custom comments column heading</h3>
<div id="_customcolname" class="comments">...</div>

I have exactly the same experience.

I cannot replicate that with a default stylesheet in preferences->look & feel->book details. With that pressing enter, shift+enter and enter again to create <p><br></p> renders are two blank lines always, everywhere.
Kovid I didn't press enter, shift+enter after 'line 2'. I pressed enter, enter. Doing that in 3.48 emits this HTML:

<div>line 1<div>line 2</div><div><br></div><div>line 3</div><div>line 4</div></div>
Which doesn't create the extra blank line in the rendered text.

What is it you are actually trying to do?? If you want to create a blank line, with the default stylesheet just press enter once and start typing the next paragraph. If you want to insert a line-break press shift enter and start typing the next line.

And yes calibre 4 is not going to behave like calibre 3 in this respect as I have explained ad nauseum.

And this will preserve the inserted <p><br></p> as a single blank line, at the cost of it now looking like: <p style="-qt-paragraph-type:empty"><br></p>

↑ ↑ ↑ ✔ - Thanks

The only suggestion to use shift+enter I can find is this one

I must have missed it. It also got conflated it with the p { margin: 0} solution.

Added : I don't really care what the code looks like - for simple notes etc I rather not have to look at it.

So, to get the expected behavior (like that of a W3C compliant browser) you have to add a specific Qt CSS property ?! (or to be exact, kept)
Absolutely obvious.
All right, then. Just in case, could you try <p></p> if it works?
I know currently than Calibre filter and delete empty paragraphs, but if it works, it would be probaly a more elegant solution.

#17  kovidgoyal 01-16-2020, 05:38 AM
No, empty paragraph is simply discarded by QTextBrowser. However, with yet another workaround for a Qt bug, <p>&nbsp;</p> does work, so I have changed it to that.

#18  un_pogaz 01-16-2020, 06:18 AM
YES, thanks.
Also work in 4.8 and propably all V4.

EDIT: Arf NOoooo
The HTML view repalce all entities. And worse, replace "unbreakable space" by "normal space"

The HTML <p>&nbsp;</p> becomes <p> </p> (with normal space) and will therefore be deleted the next time it is loaded in HTML mode.

You need to include the fix using PlainTextEdit from that patch. That works around the bug with QPlainTextEdit replacing nbsp

The update is arrived and bug report:
When I switch from "HTML code" to "Normal View", this message appears and the changes are not saved.
