I enjoy using i3wm, big time. You can switch to different windows/apps conveniently with it. The only problem to me is that it’s not beautiful enough, and it’s ridiculously small in my high-resolution screen. So I decided to change it a little bit.
Here is what you would get after applying the method.
To change the appearance, you only need to modify the config file, usually it’s ~/.config/i3/config. Add the following lines.
font pango:nimbus sans 18
status_command conky -c $HOME/.i3/conky/conkyrc
focused_workspace #F1F2F6 #F1F2F6 #4FC0E8
active_workspace #F1F2F6 #F1F2F6 #4FC0E8
inactive_workspace #F1F2F6 #F1F2F6 #C1D1E0
urgent_workspace #F1F2F6 #F1F2F6 #C1D1E0
Remove those lines.
font pango:DejaVu Sans Mono 10 (Or whatever the font is)
Then install conky and font-awesome, create a new file ~/.i3/conky/conkyrc, put the following lines in it.
