I found Margin controls work if I changed to print view, but also my kool color background vanished to white

But "WEB LAYOUT" view is supposed to use maximum area for text, so no margins, which is how it worked in my word 2010.

But in Word 2019 web layout adds margins to left & right of about 1 CM which cant seem to be turned off.

Web Layout is the view I use for the best effect for what my framepage hub is for.

Now I have defined the issue better, can anyone help?

thanks in advance
