5. Stylesheets
In3 supports stylesheets per output-type.
It is also possible to put some information in
meta.in.
5.1. Meta.in
The goal of
meta.in
is to provide meta-information about the text. It is not meant to generate output.
In a
meta.in
you generally provide information like:
title
|
The title of the complete document
|
subtitle
|
The subtitle of the complete document
|
author
|
The author
|
cover
|
The image that should be on the cover. Using an image that is 1200x1600 gives the best results.
|
set cp2, cp3 ...
|
set conditional new page to keep headers with their text.
|
As an example,
https://dullaart.website/oevres_literaires_francaises/total.pdf
uses the following
meta.in:
.cover cover.jpg .title Sélection d'oevres littéraires .subtitle Condensées et annotées à l'usage de l'enseignement secondaire .author L. Dullaart .keywords French litterature, abstracts, literature français, enseignement, uittreksel Frans .set cp2 15 .set cp3 12
5.2. HTML style sheet
If a
stylesheet.css
exists in the current directory, it is called in the HTML code. You can
create styles for all the normal HTML elements.
Example:
table.normal {
border: 1px solid #ddd;
}
In addition,
in3html
creates div-containers for specific text-elements:
class/style
|
text element
|
example
|
alinea
|
standard alinea
|
·alinea { background-color: #DDDD00; }
|
alinea
|
alinea with a specific font
|
·alineacourier { font-family: "Courier New", Courier; }
|
fixed
|
font for fixed character-width
|
·fixed { font-family:courier, "courier new", monospace; }
|
cel
|
cell in a normal table
|
·cel { background-color: #DD00DD; }
|
left
|
left notes
|
·left { font-size: 80%; }
|
list
|
format for all lists
|
·list { background-color: #00DDDD; }
|
side
|
side notes (right hand side)
|
·side { font-size: 50%; background-color: #DD0000; }
|
table·note
|
the layout of notes; mostly used to align notes
|
table·note td { vertical-allign: top; }
|
toc
|
Table of contents
|
·toc { color: #000000; background-color: #DDDDDD; width: 100%; }
|
td.leftcol
|
column of the left-notes
|
td.leftcol { width: 15%; }
|
td.alineacol
|
column of the alinea
|
td.alineacol{ width: 15%; }
|
td.side
|
column of the side-notes
|
td.sidecol { width: 15%; }
|
For class blocks, a specific class is created, with the name of the block. These can
be used in the css sheet, for example:
div.classtest {
color: #BB0000;
}
with a block definition of
.block classtest this is in the block .block
will produce:
this is in the block
5.3. Groff style sheet
For Groff, a modified set of mm macros, called
in,
is used.
Example:
.ds Licon "Table of Contents" .nr Ej 1 .ds HF HB HB HI HI I I I .ds HP 16 12 12 0 0 0 0 .nr Hb 4 .nr Hs 1 .nr Hps 0 .ds pg*header ''- \\nP -''
The stylesheet for groff, which is called
stylesheet.mm,
because I used mm before I started tinkering with the groff macro's, can be used to change
the appearance of the pdf-files. Most of the information is the same as for the mm macro set.
Note that in3 does not (yet) support all the possibilities that an mm document has. Currently
supported is:
.ds licon txt
|
Use txt as the header of the table of contents.
|
.nr Ej n
|
Eject a page before a header at level n
|
.nr Eo n
|
Eject to make sure separator pages and H1 are on odd numbered pages.
|
.ds HF l1 l2 ...
|
Define the header font for level l1, l2, ... Use either numerical font or by groff abbreviation
|
.ds HP l1 l2 ...
|
Define the header pitch size for level l1, l2, ... 0 is the same size as normal text.
|
.nr Hb n
|
Heading break level
|
.nr Hc n
|
Heading center level
|
.nr Hs n
|
Heading style; 0-> 1.1.1... , 1-> single
|
.ds pg*header ''text''
|
Use text as page header
|
.ds pg*footer ''text''
|
Use text as page footer
|
As an example,
https://dullaart.website/oevres_literaires_francaises/total.pdf
uses the following
stylesheet.mm:
.nr Ej 1 .nr Eo 1 .ds HF 3 3 2 2 2 2 2 .nr Hb 4 .nr Hs 1 .nr Hps 0 .ds HP 14 12 12 0 0 0 0 .ds Licon "Table des mati\[`e]res .ds pg*header .ds pg*footer ''- \\nP -''
Fonts can be loaded at positions to change the appearance of the document.
The font number can also be used the
HF
definition of header-fonts. The following fonts are default:
Nr
|
Font
|
Used for
|
1
|
Times
|
normal text, lists etc. Also for underlined text
|
2
|
Times Italic
|
Italic text
|
3
|
Times Bold
|
Bold text
|
4
|
Times Bold Italic
|
Bold italic text
|
6
|
Courier
|
fixed fonts
|
In addition, in3 will download the font SFOR to provide russian characters. The font is loaded
and referenced by name, never by number.
For class blocks, defined with
block classxxx,
an environment can be created wth the class name. Within the environment, all things
may be changed. At the end of the block, the environment will be popped off the stack.
Because classes are implemented as environments, all class blocks will produce a line
break in the pdf output. This means that the PDF output does not support inline class blocks.
An example of the class block:
.ev classtest .gcolor red .ev
