Stop image from auto resizing with different resolution

I would like to stop the white triangle in the background of this page from resizing thus overlapping things when the screen resolution changes. I have another one on another page.

Can you please help, I can locate the block id I just need a solution before the site can go live.

Any chance you can help @tuanphan thanks 🙂

Hi, please share a link to your website so we can check easier. Have you tried editing the mobile mode to make sure the layout and size is how you want it?

thanks @melody495 the shape is very problematic and not translatable in mobile which has been problematic.
