Hi there,
This may be a trivial issue, but is there a way to use elements defined in the xaringan css with parameters? To make an easy example, .pull-left and .pull-right are defined to have width: 47% (I think that's the default value, not the one that I have made default...). Anyway, of course one can redefine them globally, eg by setting the width to a different value (but, as I understand it, this applies to all .pull-* elements throughout the slides), or by defining new elements, say .my-pull-* with set widths (different than the default).

But I wonder whether you can do something like I believe is possible in quarto, which mimics LaTeX and defines a general "environment" columns, under which you place suitable column where you can specify the width, eg

::: {.columns}
::: {.column width="20%"}
XXX
:::
::: {.column width="80%"}
YYY
:::
:::

say, something like

.pull-left[XXX]{width="20%"}

or something?

It may well be a trivial thing to do --- I am probably not that good with css to figure out myself...

Thanks for your help!
