"block" Statements
"block": An XSL-FO element serving as an action statement to generate one block area
by working through the enclosed content.
"block" statements are used inside "flow" or "static-content" statement for form a flow of
block areas to be mapped to specific region in a layout.
For example:
<fo:flow flow-name="body_region_name">
<fo:block break-before="page|column|auto" color="#000000"
keep-together="always|auto"
linefeed-treatment="ignore|preserve|treat-as-space"
span="all|none" space-before="0.2in" space-after="0.1in"
padding-before="0.2pt" padding-after="0.1pt"
text-align="start|center|end|justify" text-indent="0.5in"
white-space-treatment="ignore|preserve"
white-space-collapse="false|true" wrap-option="wrap|no-wrap"
font-family="serif|sans-serif|cursive|monospace"
font-size="12pt" font-style="normal|italic|oblique"
font-weight="normal|bold|lighter">
mixture of text, inline and block area generations statements
</fo:block>
</fo:flow>
Some attributes and rules used in "block" statements:
- If a block area is enclosed in the content, it will be stacked as a sub block in the block
prograssion direction.
- If an inline area is enclosed in the content, it will be stacked into the current
line area in the inline prograssion direction.
- If the current line area is full (reached the end edge of the block area), it will
be stacked as a sub block.
- If a string of text is enclosed in the content, it will be broken into characters
then converted into inline areas one area per character.
- break-before: Makes this block to be the first one on a new page or column.
- break-after: Makes this block to be the last one on a page or column.
- color: Specifies the color of the text content of this block.
- span: Specifies that this block spans to all columns or not.
- Other groups of attributes allowed include: margin, border, padding and background.
- space-before: Specifies blank space before the block and outside of the border.
- padding-before: Specifies blank space inside of the border before the content.
"inline" Statements
"inline": An XSL-FO element serving as an action statement to generate
inline areas.
"inline" statements are used inside "inline" or "block" statements.
For example:
<fo:flow flow-name="body_region_name">
<fo:block>
<fo:inline color="#000000" keep-together="always|auto"
font-family="serif|sans-serif|cursive|monospace"
font-size="12pt" font-style="normal|italic|oblique"
font-weight="normal|bold|lighter">
mixture of text, inline and block area generations statements
</fo:inline>
</fo:block>
</fo:flow>
Some attributes and rules used in "block" statements:
- If block area is enclosed in the content, it will be break the current inline stacking
and start block stacking.
- Other groups of attributes allowed include: margin, border, padding and background.
