Adding an abstract to document using markdown division

[dmkaplan2000]

Hi,

I am trying to use quarto_titlepages for a scientific article with an abstract. In the guide, you suggest using a titlepage-include-file, but I found that that was not particularly effective as the abstract was not full justified (though I am likely not expert enough in LaTeX to get it right). Instead I found that using a markdown division at the very beginning of the paper text was an effective way to add an abstract:

::: {.center data-latex=""}
**ABSTRACT**
:::

::: {.abstract data-latex=""}
This is my abstract.

Cheers,
David
