remove indent from 1st line of chapter only

[cybmole]

is there a quick way to do this without having to go to stylesheet & define a new class ?

every book I inspected has same tags for 1st line of chapter as for rest of chapter text.

as I was advised in another thread I can locate them with regex, by looking for the preceeding closing h2 tag - but is there anything I can to in a regex replace that will overwrite the default indent also

I tried to guess solutions e.g. byb adding text-indent directly afdter the class, but I get syntax errors.

I begin to think it's a lot of work to edit books for this one small visual change but if there is a slicker way....

so I can find

end of chapter title </h2> space <p class = whatever.>... start of 1st line

i want to to replace / edit the p class bit because my p has a default indent, and I want to overrule it just for this line.

can it be done ?

updates - this removes the initial indent, but can I combine it with the class = bit somehow

find (regex)
</h2>\s*<p class="calibre9"
replace
</h2> <p style "text-indent: 0"

otherwise it loses other attributes of the calibre9 class

something else untoward is happening with the above code
sigil is extracting that change & creating a new class definition
p.sgc-1 {text-indent:}

but it is losing the trailing zero in doing so & thus not working as intended. I can't figure out why it's losing that last zero - AHA - it cannot cope with embedded spaces - this replace is OK </h2> <p style "text-indent:0"

It should work I think. It would be nicer and more structured to define a special class for it in the stylesheet though.

If you don't want Sigil to create a instyle sgc-1, you need to switch of Tidy. That is what is causing that. I am not quite sure why the 0 is removed, perhaps it is a bug.

As long as the <p> tags don't have a over-riding class assigned to them you can just do this in the css:

h2 + p {
text-indent:0;
}
p {
text-indent:whatever;
}

If there is an over-riding class I believe the above should still work as long as you remove any indent settings from that class.

there is always some calibre class following the <p, and it s the same class ( per book) whether the line is 1st in chapter or later in chapter but now that I know where to add spaces & where not to, to satisfy the tidy function, all is well

I am now using this - which preserves my preferred <p linespacing
find
</h2>\s*<p class="calibreN"
where N is is the right value for that book
replace all
</h2> <p style "text-indent:0;margin-bottom:0.3em"

then I go to stylesheet & edit margin-bottom to 0.3em for that same calibre style

I can do a book in well under a minute with this technique, as I do not have to add any new lines to style sheet

this is my manual workaround for the issue discussed ad-nauseum in other threads, after calibre had removed all blank lines.


PS

your h2+P ... construction - does that apply to a p following a h2 only, then ?

Yes, that's what the "+" means, it applies only to the second tag, when the two tags are adjacent.

If, in your case, all <p> are <p class="calibre10">, for instance, you can add to the stylesheet:

h2 + p.calibre10 { text-indent: 0 }

and it should have a higher priority than just "p.calibre10", because it is more specific.

One should also do the same for the paragraph immediately following a section break, but that's probably a lot more difficult to programatically define.

there's no HTML code as such for a section break is there - folks just add a blank line or two, or some squiggles ?

Yes, that's exactly my point: that there's probably no way to automate it; the indent would need to be removed manually from the paragraph immediately following a section break.

It depends of the book. If it's well formatted you might have:

<p>Some paragraph.</p>
<div class="break">* * *</div>
<p>Another paragraph after a "scene change".</p>

or just:

<p>Some paragraph.</p>
<p class="spaced">Another paragraph after a "scene change".</p>

Calibre probably changes class names, but those should be easy to style to remove the indent (use "p.spaced" or "div.break + p").

[HarryT]

If the book is that well-formatted, though, you probably wouldn't have the issue in the first place. Unfortunately there comes a point in almost every eBook where you just have to get stuck in and edit manually.

If you're converting in Calibre and enable the heuristics option to detect and format scene breaks you can add the following to Calibre's extra CSS:

p.softbreak+p, p.scenebreak+p {text-indent:0}

Works in a fair number of common cases, and it should improve over time. Of course if you've already converted once using Calibre then you may need to find what calibrexxx tag your paragraphs are using and do something along the lines of what Jelby described earlier.

I have searched in vain for a crib sheet / tutorial book that defines these types of + constructions, also for one that explains the use of <h> without a number, in style definitions, can you recommend links / books please

Look for "CSS selectors", the spec is here

For <h> with no number, I don't think you can use in anywhere, all you can do is put all 6 instances in a list:

h1, h2, h3, h4, h5, h6 { text-align: center }

Maybe this will help, also includes a link to the correct w3c docs:
