Customize Gnome shell theme

The best thing in Linux is its various desktop environments available there and mostly the Gnome has its own impact in the Linux users community. Sometimes we choose to customize the looks. Well! I thought I would like to make my shell transparent with the darkish look.  Let's customize things.

1. Download Your preferred theme from gnome-look, I chose a transparent shell theme https://www.gnome-look.org/p/1203425/ .
2. Now extract the file.
3. Then make .theme folder in usr directory (shows if exists).                                                 mkdir  ~/.themes
4. Now move the extracted file into the themes directory mv extracted_file  ~/.theme
5. Now install the gnome-tweak tool to select our theme.                                                               sudo apt-get install gnome-tweak-tool
6. open Tweaks --> Appearance --> shell --> Extracted file (select). 

Now you can see the changes applied to your shell. ..!!
