* <li><b>textAlign</b> (String): [left, center, right, justify] The

* <li><b>textAlignLast</b> (String): [left, center, right, justify]: The

* <li><b>textIndent</b> (Number): The indentation of the first line of
* text in a paragraph. The indent is relative to the left margin.
* Measured in pixels. Default is 0. Can be negative.</li>
* <li><b>marginLeft</b> (Number): The indentation applied to the left edge.
* Measured in pixels. Default is 0.</li>
* <li><b>marginRight</b> (Number): The indentation applied to the right

* <li><b>marginTop</b> (Number): This is the "space before" the paragraph.
* Default is 0. Minimum is 0.</li>
* <li><b>marginBottom</b> (Number): This is the "spaceAfter" the paragraph.
* Default is 0. Minimum is 0.</li>
* <li><b>direction</b> (String): [ltr, rtl] Controls the dominant writing
* direction for the paragraphs (left-to-right or right-to-left), Default
* is ltr.</li>
