Hello,
I needed a MessageBox, and since it doesn’t exist in glide, I did it with CSS.
You can adapt it to your needs.
For the demo, click on the “floating button” to make it appear.
When the “MsgBox” is visible, you normally can’t click anything else.
Here is a small demo application.
EDIT : I retrieve a part of CSS in the community (but I no longer have the author), I just adapted with buttons.
Very nice! 
Very useful, thank you for putting together and sharing 
Great work - I’ll be putting this into my app 
cheers!
Well done! First time I’ve seen this implemented successfully and beautifully complete with buttons/actions.
Glide should take note that this modal window screen would be an awesome addition. Even if something simple as an option to the “link to screen” action that I requested here:
Following @Mark_Turrell remark, I made some adjustments for tablet / desktop mode
Cool - can you share your CSS? thanks!
Normally I updated the demo app. but hey here are the CSS’s.

Thank you!
Had an opportunity to use this tonight. Thanks again, @Manu.n

Slick!
Funny, when it’s @Robert_Petitto , it’s always better!
For information:
You can replace

through
background: linear gradient (#FFFFFF, #808080);
or other color of your choice.
