CSS style declaration bytecode
|
|
==============================
|
|
|
|
Format
|
|
------
|
|
|
|
<opcode+flags+value> [<parameters>]
|
|
|
|
<opcode+flags+value> is 32 bits wide:
|
|
bits 18-31: value
|
|
bits 10-17 : flags
|
|
bits 0-9 : opcode
|
|
|
|
The 8 bits of flag data are defined as follows:
|
|
bits 2-7: MBZ
|
|
bit 1 : value is inherit
|
|
bit 0 : value is important
|
|
|
|
The 14 bits of value are opcode-specific.
|
|
|
|
Parameters are opcode-specific. Each parameter must begin on a 4 byte boundary.
|
|
|
|
Datatype storage
|
|
----------------
|
|
|
|
All numeric values are stored in a 32bit wide field. This field contains
|
|
a fixed point value with 22 bits assigned to the integer part and 10 bits
|
|
assigned to the fractional part.
|
|
|
|
Strings are stored as a 32bit index into a table of interned string pointers.
|
|
The table is found in the stylesheet object.
|
|
|
|
CSS dimensions are stored as two 32bit values: <length, units>.
|
|
Length is a 32bit numeric value (as described above) and unit is as follows:
|
|
|
|
bit 8 clear => length unit
|
|
bits 9-31: MBZ
|
|
bits 0-7 :
|
|
00000000 => px
|
|
00000001 => ex
|
|
00000010 => em
|
|
00000011 => in
|
|
00000100 => cm
|
|
00000101 => mm
|
|
00000110 => pt
|
|
00000111 => pc
|
|
|
|
bit 8 set => percentage unit
|
|
bits 9-31: MBZ
|
|
bits 0-7 : MBZ
|
|
|
|
bit 9 set => angle unit
|
|
bits 10-31: MBZ
|
|
bit 8 : MBZ
|
|
bits 0-7 :
|
|
00000000 => deg
|
|
00000001 => grad
|
|
00000010 => rad
|
|
|
|
bit 10 set => time unit
|
|
bits 11-31: MBZ
|
|
bits 8-9 : MBZ
|
|
bits 0-7 :
|
|
00000000 => ms
|
|
00000001 => s
|
|
|
|
bit 11 set => frequency unit
|
|
bits 12-31: MBZ
|
|
bits 8-10 : MBZ
|
|
bits 0-7 :
|
|
00000000 => Hz
|
|
00000001 => kHz
|
|
|
|
CSS colours are stored as one 32bit value. See "Colour" for their format.
|
|
|
|
Shorthand properties
|
|
--------------------
|
|
|
|
The CSS shorthand properties are handled by decomposing them to their
|
|
component parts, and then creating bytecode for these.
|
|
|
|
For example, "background: red none no-repeat scroll left top !important;" would
|
|
be decomposed to:
|
|
|
|
background-color: red !important;
|
|
background-image: none !important;
|
|
background-repeat: no-repeat !important;
|
|
background-attachment: scroll !important;
|
|
background-position: left top !important;
|
|
|
|
and bytecode generated for each of these properties.
|
|
|
|
The full list of CSS 2.1 shorthand properties is:
|
|
|
|
background
|
|
border-color
|
|
border-style
|
|
border-{top,right,bottom,left}
|
|
border-width

|
|
font
|
|
list-style
|
|

<value> (14bits) :

|
|
bit 7 clear => keywords:
|
|
bits 0-6: 0000000 => auto,
|

|
|
|
|
If the value is rect(top, right, bottom, left), then bits 3-6 encode
|
|
which of <top>, <right>, <bottom>, <left> is set to auto. The
|
|
subsequent parameter list is then 4 - <auto_side> entries long.
|
|
Each entry is a dimension. Entries are always ordered top, right,
|
|
bottom, left.
|
|
|
|
For example,
|
|
clip: rect(10px, auto, auto, 10px)
|
|
would produce the following bytecode:
|
|
|
|
<02c00017> <00002800> <00000000> <00002800> <00000000>

0000100 => no-open-quote,
|
|
0000101 => no-close-quote,
|
|
other => rffe.
|
|
|
|
If the value is not "normal", "none", or "inherit", then there is
|
|
a parameter list. Each item is preceded by a <value> word which
|
|
declares the type of the next item. The list is terminated by a
|
|
word with all bits set to zero (the encoding for "normal").
|
|
|
|
For example,
|
|
content: open-quote url('http://example.com/')
|
|
" : " attr(name) " " counter(x) "." counters(y, ".")
|
|
close-quote;"
|
|
would result in the following bytecode:
|
|
|
|
<00080019>
|
|
<00000081> <ptr to "http://example.com">
|
|
<00000080> <ptr to " : ">
|
|
<00000084> <ptr to "name">
|
|
<00000080> <ptr to " ">
|
|
<00000382> <ptr to "x">

|
<00000080> <ptr to ".">
|

If the value is not "none", or "inherit", then there is a parameter

list. Each item is preceded by a <value> word which declares the type
