Is there a way . . .

@sean Can you explain your body code a bit? I’m not quite following it.

In modern CSS, you can use variables. If you are using values referenced frequently or dependently, you can set that value as variables.
In prior example, --body-margin is defined. Now you can use it instead static fixed value 20px. So when you have to change that value, just modify --body-margin once.

This is the part that’s getting me…

width: calc(100vh - var(–body-margin) * 2);
height: calc(100vw - var(–body-margin) * 2);

If I’m reading this correctly - it’s taking the calculation of 100% of the viewpoint(direction) - the margin defined in the varible multiplied by 2?

100% of the viewport height minus 40 pixels in your example?

Yes. you are right.
Just one point, user-defined property should be start with -- not -

@bkeyport margin is both sides, or top and bottom. All the way around.

If u look at the original the width is hard coded at 100%- 2 times the margin value

@sdetweil so, then because I have to use the following:

body {
margin: 0px;
height: calc(100vh - 10px);
width: calc(100vw - 5px);
}

am I correct in assuming that magicmirror sees the screen a few pixels bigger than it really is - and that’s being expressed by running off the right and bottom of the screen when I don’t have the 10px subtract from height, and the 5px subtract from width?

@bkeyport I also had a heck of a time modifying body to get a fullscreen image.
I finally changed to use the .fullscreen.above css setting. I was also worried that if I required body to be changed and some else’s module also required body changed, then the conflict would mess up my display.

No - the screen is the size it is.

Your CSS above doesn’t make sense (you’re setting a body height that’s 10px smaller than the window height). If you set the body height to be 100vh and you get a vertical scrollbar, it’s because of another margin that’s pushing the body element.

In general, it’s good practice to also do:

html {
    margin: 0;
    padding: 0;
}

to avoid situations like this.

@michael5r - Actually, I don’t get scrollbars at all. If I don’t subtract back from the 100vh/100vw or 100% - It’ll just run off the edge of the screen as if the system is seeing the screen (In this case, the RasPi’s 7" touchscreen) bigger than it is. With it set the way I have it, everything is dead on edge, giving the maximum use of the screen.

I’m glad it works for you, but it still doesn’t make any sense :)
