i3 wm, hide window title bar

gistfile1.md

deprecated

for_window [class="^.*"] border pixel 1
new_window 1pixel

thanks to deviatorslegacy's comment
Document here: https://i3wm.org/docs/userguide.html#_default_border_style_for_new_windows

New way to do it:

default_border pixel 1
default_floating_border pixel 1

Additionally, I could assign color to border when window focus is changed. https://i3wm.org/docs/userguide.html#_changing_colors

Thanks @qordaz

In case some of you might want to remove the title bar entirely :

int render_deco_height(void) {
     return 0;
}

That's what I did, not sure if that's how it supposed to be done..

Thanks @Antiz96 <3
This last command worked perfectly :)

#Hide window title bar
default_border pixel 1
default_floating_border pixel 1
for_window [class="^.*"] border pixel 1
