Construct a raw HTML text box item
html_text_box.RdLike [text_box()], but `label` is treated as HTML and passed directly to `gridtext` for rendering. Supports the gridtext HTML subset: `<b>`, `<i>`, `<em>`, `<strong>`, `<code>`, `<span style="...">`, `<br/>`, `<sup>`, `<sub>`. Links render as styled text but are not clickable in PDF.
Usage
html_text_box(
label,
text_style = NULL,
box_style = NULL,
bg = NULL,
pad_x = NULL,
pad_y = NULL
)
