I am unable to identify your issue by looking at the link.
Can you please consolidate your file to a single muse page with only relevant matter and send it across so we can have a look at?
Please use the instructions mentioned in here for sharing the file - Please Provide a .muse File to Help Us Fixing Your Issue!
Background is grey in that example and it fills the entire browser viewport.
Could you further explain just what it is you have issue with?
yes i understand the back ground is grey but what i call the background of the page is white its a white rectangle that i want to have stretch from the footer to the header depending on how much content is in the page. i find a way to lock it in to fill the space between the top and bottom of page . i hope that answers your question
i am testing with screenfly and many tests are fine but a few just wont snap to the top or bottom.
Elements of 100 % height unfortunately aren‘t supported in actual Muse.
In simple use cases (for example coloured areas) you can easily simulate this behaviour:
Place a rectangle at the bottom of the page, define it as a footer element, and drag its upper edge way over the top of your page. The overlapping part normally isn‘t shown, but if you resize the browser window verticall, it will shift into sight and continue filling the screen.
Alternatively, you can use two considerably overlapping elements: One at the top of your page, one at the bottom, defined as a footer object.
