div wider than the standard size?

[paugier]

For some slides, I'd need to put content in a wide div, wider than the standard width of the presentation.

I tried with

<div align="left"  style="width: 100vw; position: relative; left: calc(-50vw + 50%);">

which indeed create a wide div but the content can be seen only on the center of the screen, so it is useless.

Is there a workaround for this problem? Would it be possible to be able to create such wide div?
