These frame parameters enable or disable various parts of the frame, or control their sizes.
The width in pixels of the frame’s border.
The distance in pixels between text (or fringe) and the frame’s border.
Whether the frame has scroll bars for vertical scrolling, and which side
of the frame they should be on. The possible values are
nil for no scroll bars.
The width of vertical scroll bars, in pixels, or
nil meaning to
use the default width.
The default width of the left and right fringes of windows in this frame (see Fringes). If either of these is zero, that effectively removes the corresponding fringe.
When you use
frame-parameter to query the value of either of
these two frame parameters, the return value is always an integer.

imposes an actual default value of 8 pixels.
The combined fringe widths must add up to an integral number of
columns, so the actual default fringe widths for the frame, as
frame-parameter, may be larger than what you
specify. Any extra width is distributed evenly between the left and
right fringe. However, you can force one fringe or the other to a
precise width by specifying that width as a negative integer. If both
widths are negative, only the left fringe gets the specified width.
The width (thickness) reserved for the right divider (see Window Dividers) of any window on the frame, in pixels. A value of zero means to not draw right dividers.
The width (thickness) reserved for the bottom divider (see Window Dividers) of any window on the frame, in pixels. A value of zero means to not draw bottom dividers.
The number of lines to allocate at the top of the frame for a menu bar. The default is 1 if Menu Bar mode is enabled, and 0 otherwise. See Menu Bars in The GNU Emacs Manual.
The number of lines to use for the tool bar. The default is 1 if Tool Bar mode is enabled, and 0 otherwise. See Tool Bars in The GNU Emacs Manual.
The position of the tool bar. Currently only for the GTK tool bar.

The default is
Additional space to leave below each text line, in pixels (a positive integer). See Line Height, for more information.
