xhmtl2pdf只支持数量有限的css属性，如docs page中所述：

background-color
border-bottom-color, border-bottom-style, border-bottom-width
border-left-color, border-left-style, border-left-width
border-right-color, border-right-style, border-right-width
border-top-color, border-top-style, border-top-width
colordisplay
font-family, font-size, font-style, font-weight
height
line-height, list-style-type
margin-bottom, margin-left, margin-right, margin-top
padding-bottom, padding-left, padding-right, padding-top
page-break-after, page-break-before
size
text-align, text-decoration, text-indent
vertical-align
white-space
width
zoom

并添加了一些用于定义自己样式的功能：

-pdf-frame-border
-pdf-frame-break
-pdf-frame-content
-pdf-keep-with-next
-pdf-next-page
-pdf-outline
-pdf-outline-level
-pdf-outline-open
-pdf-page-break

也就是说，它不接受代码中的flex、border-collapse和border-spacing

使用它的pages and frames to define layout而不是flex列

doc还表示，它有一些页面的默认样式，您可以转储、编辑或替换这些样式，如here所述：

# dump
$ xhtml2pdf  css-dump > xhtml2pdf-default.css

# replace
$ xhtml2pdf  css=xhtml2pdf-default.css test.html
