edit: your content needs to match PowerPoint template layout.

1. width is actually not supported by Pandoc thus Quarto (both documentation is not updated yet on that)
2. there are no "one column" layout which is possibly the issue as Pandoc tries to fit the content in one of the layout.

Outdated.

Could you share a small self-contained "working" (reproducible) example to work with, i.e., a complete Quarto document or a Git repository? The goal is to make it as easy as possible for us to recreate your problem so that we can fix it: please help us help you! Thanks.

This being said,

You can share a self-contained "working" (reproducible) Quarto document using the following syntax, i.e., using more backticks than you have in your document (usually four ````).
See https://quarto.org/bug-reports.html#small-is-beautiful-aim-for-a-single-document-with-10-lines.

If you have multiple files (and if it is absolutely required to have multiple files), please share as a Git repository.

R	Python
````qmd --- title: "Reproducible Quarto Document" format: html engine: knitr --- This is a reproducible Quarto document. {{< lipsum 1 >}} ```{r} x <- c(1, 2, 3, 4, 5) y <- c(1, 4, 9, 16, 25) plot(x, y) ``` {#fig-placeholder} {{< lipsum 1 >}} The end after @fig-placeholder. ````	````qmd --- title: "Reproducible Quarto Document" format: html engine: jupyter --- This is a reproducible Quarto document. {{< lipsum 1 >}} ```{python} import matplotlib.pyplot as plt x = [1, 2, 3, 4, 5] y = [1, 4, 9, 16, 25] plt.plot(x, y) plt.show() ``` {#fig-placeholder} {{< lipsum 1 >}} The end after @fig-placeholder. ````

Additionally and if not already given, please share the output of quarto check within a code blocks (i.e., using three backticks ```txt), see https://quarto.org/bug-reports.html#check.

Beside the fact that a "one column" layout does not exist, the issue comes directly from Pandoc.
Note that the "workaround" is to not use column at all if you don't intend to have columns.

## Slide

:::: {.columns}
::: {.column}

Out of curiosity what were you trying to do?

[kernie]

It doesn't work for 2 either... So I tried to have 2 columns, left column with text and right one with image, which is a classical (boring) presentation layout... 23.06.2024 00:13:26 Mickaël Canouil ***@***.***>:

After comparing your source code and mine I saw that I had an error in the class specifier (missing dot). That's my bad!
And thank you very much for your analysis!

Some observation however:

• Using one column doesn't show the image (placeholder), but two times the caption
• The proportion of two columns is always 50% : 50% for Powerpoint, but as specified for Beamer and Revealjs when doing e.g. 30% : 70% for the width

EDIT: Sorry, you mentioned this already! So closing...

[mcanouil]

Even if the single-column layout is unnecessary, I think it should still work correctly. So we should report this to Pandoc, thus reopening.
