stay example

thisisnotcss.css

base width will expand, 
because of the last rule, 
and not clamp to 100 from the second

:base {
    left: >= 100;
    width: >= 100;
    right: screen.right;
}

to keep the width the same, 
and pin the right edge only, 
add a stay on the width value.
that will hold it from being constrained by the subsequent lines

:base {
    left: >= 100;
    width: >= 100;
    stay: width;
    right: screen.right;
}
