"" This was made by Reddit user u/SamLovesNotion. Also with the help of - https://tdaly.co.uk/projects/vim-statusline-generator/ for learning the syntax. Sorry for English & grammar, this post was made in hurry.

" Add all of this at the end of your vimrc OR Create separate file like 'statusline.vim' & 'colorsgroup.vim' & source those files in your main vimrc.
" e.g. source "~/.config/vim/statusline.vim"
