I would like to pin the title of the website in the upper left and as the Brower width reduces, it stays the same width and height but the same pix from the left, but as you scroll the page it goes up with header.
Make the resize and none for "title" and browser pin the object
If I understand correctly you want the title to remain fixed at top left, right?
I have tried to do the same and it didn't go up along with scroll.
Could you please attach your .muse file with just the pinned title, so we can have a look at your workflow and suggest if any change is required.
