2023r3: centering webdialogs?

in 2023r11 all my webdialogs are centered on the screen
in 2023r3 they are on the top-left of the screen…
I know bootstrap has gone from v4 to v5
but how to make the webdialogs be centered ?

I’ve seen @AlbertoD thread about this

it centers correctly vertically on the screen, but it does not center horizontally
some more css must be added but my css-fu is at noob level …
can someone help me with this ?
thanks.

just found I left the v4 bootstrapmin.css in the project
but everything else looks fine, except the dialog centering…

with the v5 bootstrap.min.css, the webdialogs are centered on the screen,
but lots of websdk are not looking ok.
so I could keep the v4 bootstrapmincss may be ?
there would still be this centering problem.

I think the best way forward is updating the v5 bootstrap if you are going to use a newer Xojo version, so your websdk look good with that too. Depending on what you are using it could be simple or not.

If you can share sample project I can take a look.
