Looking at the counsel I'm getting that the solution to my problem is:

<meta name="viewport" content="width=device-width, initial-scale=1" />

.... and

ok so a viewport

which I would assume is, you know, the browser window

should have a width which is the width of the device

which is I guess the browser window

and scale of "one"

and I assume that I just don't know what words mean or what a web page or screen are

because

is that not like

<plz be normal web browser on computer>
