\begin_layout Standard
With the module 
\emph on
Fancy
\begin_inset space ~
\end_inset

Colored

Boxes
\emph default
 you have access to a huge variety of colored boxes.
 They are particularly useful for presentations or educational texts where you might for example highlight results or equations.
 This document describes how these boxes are used with \SpecialChar LyX
.
\end_layout

\begin_layout Standard
The fancy boxes are generated by the \SpecialChar LaTeX
 package 
\series bold
tcolorbox
\series default
.
 This package has so many features that its manual exceeds 400
\begin_inset space ~
\end_inset

pages.
 \SpecialChar LyX
 can therefore only provide access to its basic features.
 For more advanced features and examples have a loot at the

\end_layout

\begin_layout Standard
This is a static color box:
 
\begin_inset Flex Color Box

\begin_layout Plain Layout
A basic color box.
\end_layout

\end_inset


\end_layout

\begin_layout Standard
It has by default a frame with round corners and consumes the full text width.
 It can contain several paragraphs and math.
\end_layout

\begin_layout Standard
\begin_inset Note Greyedout

\begin_layout Plain Layout

\series bold
Note:

\series default
 The box can contain forced page breaks but they will be ignored.
 To get breakable boxes,
 see 
\begin_inset CommandInset ref

nolink "false"

\end_inset

.
\end_layout

\end_inset

\begin_layout Standard
This is a dynamic color box:
 
\begin_inset Flex Dynamic Color Box

\begin_layout Plain Layout
A dynamic color box.
\end_layout

\end_inset


\end_layout

\begin_layout Standard
In contrary to static boxes dynamic boxes cannot have parts,
 see 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Box-parts"
nolink "false"

\end_inset

,
 and they cannot made breakable but one can set their vertical placement,
 see 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Vertical"
nolink "false"

\end_inset

.
 Their width is by default the width of the content.
\end_layout

\begin_layout Subsubsection

\end_layout

\begin_layout Standard
Fit boxes are dynamic boxes but their content is automatically decreased or increased to fit into the specified box width and height.
 How to specify a width and height is described in 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Geometry"
nolink "false"

\end_inset

.
 If no width and height is specified the result is a square box consuming the full available width of the page.
 If only a width is specified,
 the result is a square box.
\end_layout

\begin_layout Standard
These are fit color boxes:

\end_layout

\begin_layout Standard
\begin_inset Flex Color Box

\begin_layout Plain Layout
\begin_inset Argument 1

\end_layout

\end_inset

 The content below the subtitle.
\end_layout

\end_inset


\end_layout

\begin_layout Standard
The title and subtitle text is by default white.
 How to change its color,
 see 
\begin_inset CommandInset ref

.
\end_layout

\begin_layout Subsection
Box parts
\begin_inset CommandInset label
LatexCommand label
name "subsec:Box-parts"

\end_inset


\end_layout

\begin_layout Standard
The content of the box can be divided into an upper and a lower part by using the environment 
\family sans
Color Box Separator
\family default
 in \SpecialChar LyX
's environment selection combobox.
 The idea behind this is that both parts can be treated and customized separately.
 An application would be that the upper part contains a description and the lower part an equation.
\end_layout

\begin_layout Standard
This is a box where the content is separated:
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box
status open

\begin_layout Plain Layout
Upper content
\end_layout

\begin_layout Color Box Separator

\end_layout

\begin_layout Plain Layout
Lower content
\end_layout

\end_inset


\end_layout

\begin_layout Standard
The separation line can be customized as described in 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Lines"
nolink "false"

\end_inset

.
\end_layout

\begin_layout Standard
The separation can also be made side by side with the box option 
\series bold
sidebyside
\series default
.
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box

\begin_layout Plain Layout
\begin_inset Argument 1

\end_layout

\begin_layout Color Box Separator

\end_layout

\begin_layout Plain Layout
Lower content at the right
\end_layout

\end_inset


\end_layout

\begin_layout Standard
The separation can be made invisible with the box option 
\series bold
lower separated=false
\series default
.
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box

\begin_layout Plain Layout
\begin_inset Argument 1

\end_layout

\begin_layout Color Box Separator

\end_layout

\begin_layout Plain Layout
Lower content at the right
\end_layout

\end_inset


\end_layout

\begin_layout Standard
There are several layout skins available for colored boxes,
 see 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Beamer"
nolink "false"

\end_inset

,
 that affects also the layout of the box parts.
 For example with the box option 
\series bold
beamer
\series default
 the box parts are separated this way:
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box
status open

\begin_layout Plain Layout
\begin_inset Argument 1
status open

\begin_layout Plain Layout
beamer
\end_layout

\end_inset

Upper content
\end_layout

\begin_layout Color Box Separator

\end_layout

\begin_layout Plain Layout
Lower content
\end_layout

\end_inset


\end_layout

\begin_layout Subsection
Lines
\begin_inset CommandInset label
LatexCommand label
name "subsec:Lines"

\end_inset


\end_layout

\begin_layout Standard
To draw a line in a box use the environment 
\family sans
Color Box Line
\family default
.
 The line is by default dashed.
 Note that it is just a line and does not separate box parts!
\end_layout

\begin_layout Standard
This is a box with a line:
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box
status open

\begin_layout Plain Layout
Some text
\end_layout

\begin_layout Color Box Line

\end_layout

\begin_layout Plain Layout
Some text
\end_layout

\end_inset


\end_layout

\begin_layout Standard
The line style can only be changed if a skin is specified,
 see 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Enhanced"
nolink "false"

\end_inset

.
 Then one can use the box option 
\series bold
segmentation style={commands}
\series default
 where 
\series bold
commands
\series default
 are commands to define the style.
 See section 
\family sans
Library
\begin_inset space ~
\end_inset

skins
\family default
 of the 
\series bold

\series default
 manual for possible commands,
 
\begin_inset CommandInset citation

\end_inset

.
\end_layout

\begin_layout Standard
Here is an example in the 
\emph on

\emph default
 skin with a double blue line:
\end_layout

\begin_layout Standard

\end_layout

\begin_layout Section
Breakable boxes
\begin_inset CommandInset label
LatexCommand label
name "sec:Beakable-boxes"

\end_inset


\end_layout

\begin_layout Standard
To make a box breakable the option 
\series bold
breakable
\series default
 is added.
 If a page break occurs within a box,
 the box will get broken this way:
\end_layout

\begin_layout Standard
\begin_inset Flex Color Box

Customization
\end_layout

\begin_layout Subsection
General
\begin_inset CommandInset label
LatexCommand label
name "subsec:General"

\end_inset


\end_layout

\begin_layout Standard
The following subsections show many possibilities to customize boxes.
\end_layout

\begin_layout Standard
To avoid to write the box commands all the time,
 you can use the environment 
\family sans
Color
\begin_inset space ~
\end_inset

Box
\begin_inset space ~
\end_inset

Setup
\family default
.
 It is inserted via \SpecialChar LyX
's style selection combobox.
 There you can write all options that should be applied for 
\emph on
all
\emph default
 boxes of the document 
\emph on
following
\emph default
 the environment.
 For example writing there 
\series bold
width=3cm,
 height=8cm
\series default
 forces all following boxes to have a height of 8
\begin_inset space \thinspace{}
\end_inset

cm and a width of 3
\begin_inset space \thinspace{}
\end_inset

cm.
 However,
 this is not useful if one needs several box types since the changes would affect 
\emph on
all
\emph default
 boxes.
\end_layout

\begin_layout Standard
In most documents one need a few types of boxes and all boxes of a type should look identical.
 To achieve this the module 
\emph on
Fancy
\begin_inset space ~
\end_inset

Colored
\begin_inset space ~
\end_inset

Boxes
\emph default
 predefines 5
\begin_inset space ~
\end_inset

different box types which you can customize.
 To change their appearance use the environment 
\family sans
New
\begin_inset space ~
\end_inset

Color
\begin_inset space ~
\end_inset

Box
\begin_inset space ~
\end_inset

Type
\family default
.
 It is inserted via \SpecialChar LyX
's style selection combobox.
\end_layout

\begin_layout Standard
If you want for example a box type that looks like the fancy colored one in 
\begin_inset CommandInset ref
LatexCommand ref
reference "subsec:Enhanced"
nolink "false"

\end_inset

 use these options in the environment:
\end_layout

\begin_layout Standard

\series bold
enhanced,
 frame style={left color=red!75!black,
 right color=blue!75!black},
 interior style={left color=red!20!white,
 right color=yellow!50!white}
\end_layout

\begin_layout Standard
Into the 
\family sans
Name
\family default
 inset write 
\series bold
cBoxA
\series default
 (cBoxA is custom box type
\begin_inset space ~
\end_inset

1,
 cBoxB type
\begin_inset space ~
\end_inset

2 etc.).
 Because you want to customize every box of this type (e.
\begin_inset space \thinspace{}
\end_inset

g.
\begin_inset space \space{}
\end_inset

every box should have its own title),
 you need one argument.
 Therefore add 
\series bold
1
\series default
 into the Arguments inset of the environment.
\end_layout

\begin_layout Standard
\begin_inset Note Greyedout
status open

\begin_layout Plain Layout

\series bold
Note:

\series default
 If you use an argument,
 the inset 
\family sans
Default Value
\family default
 must also be inserted but left empty!
\end_layout

\end_inset


\end_layout

\begin_layout New Color Box Type
\begin_inset Argument 2

\begin_layout Plain Layout
cBoxA
\end_layout

\end_inset


\begin_inset Argument 3

\begin_layout Standard
This way you defined the box type 
\family sans

\begin_layout Standard
Normally the boxes are a paragraph of its own.
 They will therefore appear by default one upon another separated by vertical space.
 To change this behavior,
 to place for example boxes side by side,
 use the placement options 
\series bold
before=code
\series default
 and 
\series bold
after=code
\series default
.
 By default there is a paragraph break before and after the box.
 By using the options 
\series bold
before=,
 after=
\series default
 nothing will be added besides the boxes so that they can be places side by side:
