Azenis 2021 is based off of Azenis 2, originally created by J.J. Ying for Windowblinds. Azenis 2 won the GUI championship. Ported by EZy to KDE and to Gnome2 by JamesHardy88. Aravisian (that's this guy) later attempted a gtk 3.18 port and 3.22 port called AzenisEX that if typed in all caps had a funny name.
Azenis 2021 is built from the ground up for gtk3 rather than porting older files. I sought to incorporate the dark theme elements introduced by EZY and used by JamesHardy88, along with the original art style of J.J. Ying. There are many changes... Instead of relying on a lot of assets and images, linear gradiants have replaced many images to improve sizing and scaling. Buttons, checkboxes and Range are all examples of New design and images.
Metacity, XFWM and CSD titlebuttons have been increased, to make it easier to hit your target.

Many thanks to J.J. Ying (Jun Jui Ying) for giving his permission to continue Azenis Theme in gtk3 along with Azenis-One, a port of the Original Azenis theme entry that preceded Azenis 2.

Installation:
Extract "azenis2012.tar.gz to your /usr/share/themes folder or to ~/.themes
Apply through your settings, appearance or window manager settings.
For Mate, Cinnamon, XFCE4 Desktops.
Cinnamenu; Stark Menu; Whiskermenu:
Right click the menu icon and select properties or configure. Under appearance, select custom icon. Navigate to .../themes/Azenis 2021/cinnamon/mint-menu-icon.png. XFCE 4.16 - Youc can select "No Icon" in whiskermenu, instead.
Select this as your icon - it will act as the 'transparency' to overlay the Menu Icon Button.
XFCE4 - WhiskerMenu users MAY experience a #474747 border around the icon. To resolve if this happens; Open your Panel Settings > Appearance and select the Panel.png from /themes/Azenis 2021/whiskermenutheme as the background on the panel instead of using the system panel.

Azenis.xml file is a .css color code theme for use in Gedit, Xed, Pluma or other text editors that accept custom .xml themes for highlighting and visibility.
