/** |
|
46 |
* Defines a set of |
|
47 |
* <a href="http://www.w3.org/TR/REC-CSS1">CSS attributes</a> |
|
48 |
* as a typesafe enumeration. The HTML View implementations use |
|
49 |
* CSS attributes to determine how they will render. This also defines |
|
50 |
* methods to map between CSS/HTML/StyleConstants. Any shorthand |
|
51 |
* properties, such as font, are mapped to the intrinsic properties. |
|
52 |
* <p>The following describes the CSS properties that are suppored by the |
|
53 |
* rendering engine: |
|
54 |
* <ul><li>font-family |
|
55 |
* <li>font-style |
|
56 |
* <li>font-size (supports relative units) |
|
57 |
* <li>font-weight |
|
58 |
* <li>font |
|
59 |
* <li>color |
|
60 |
* <li>background-color (with the exception of transparent) |
|
61 |
* <li>background-image |
|
62 |
* <li>background-repeat |
|
63 |
* <li>background-position |
|
64 |
* <li>background |
|
65 |
* <li>background-repeat |
|
66 |
* <li>text-decoration (with the exception of blink and overline) |
|
67 |
* <li>vertical-align (only sup and super) |
|
68 |
* <li>text-align (justify is treated as center) |
|
69 |
* <li>margin-top |
|
70 |
* <li>margin-right |
|
71 |
* <li>margin-bottom |
|
72 |
* <li>margin-left |
|
73 |
* <li>margin |
|
74 |
* <li>padding-top |
|
75 |
* <li>padding-right |
|
76 |
* <li>padding-bottom |
|
77 |
* <li>padding-left |
|
78 |
* <li>border-style (only supports inset, outset and none) |
|
79 |
* <li>list-style-type |
|
80 |
* <li>list-style-position |
|
81 |
* </ul> |
|
82 |
* The following are modeled, but currently not rendered. |
|
83 |
* <ul><li>font-variant |
|
84 |
* <li>background-attachment (background always treated as scroll) |
|
85 |
* <li>word-spacing |
|
86 |
* <li>letter-spacing |
|
87 |
* <li>text-indent |
|
88 |
* <li>text-transform |
|
89 |
* <li>line-height |
|
90 |
* <li>border-top-width (this is used to indicate if a border should be used) |
|
91 |
* <li>border-right-width |
|
92 |
* <li>border-bottom-width |
|
93 |
* <li>border-left-width |
|
94 |
* <li>border-width |
|
95 |
* <li>border-top |
|
96 |
* <li>border-right |

97 |
* <li>border-bottom |

109 |

110 |
