I want to adjust the size of a block (in which text appears), but want the size change to be effected on all slides in the library (template slides) that have that block. I have watched various videos, but I have not found a way to do that yet.
There is a semi-transparent white block over a photo (on which text will appear) … but I can’t change the size of that white block. When I hover over the edges of the block, there is no option (arrows) to make it larger.
I hope you can help
