Resize frame of monitor screen to fit mirror dimensions

[Jacob66]

The size of monitor screen is slightly larger than the frame of my mirror, this means that part of the text is cut off by the frame. Is there a way (other than just zooming in or out) that I can shrink the display size? Or have it only run on part of the screen?

@Jacob66 Adjust the margin in css

body {
  margin: 100px;
  height: calc(100% - 200px);
  width: calc(100% - 200px);
}

Add that to your custom.css file

when you adjust the margin remember to remove double that on the height and width.

I think the RPi itself can also draw a ‘black frame’. Search for the term “overlay”. It is a setting in the /boot/config.txt of RPi sdcard.

But probably the css modification above is more elegant…
