Xfce How to create Arc-Lighter hdpi theme

Hi everyone,
I am trying to get Arc-Lighter theme increase default to hdpi.
I realise there is Default-hdpi but I prefer Arc-Lighter. The window buttons are too small, for my bad eyesight.
I did find this: https://github.com/loichu/arc-theme-xfwm4-hidpi

and then tried: https://github.com/horst3180/arc-theme#manual-installation

I have no idea what I’m doing. I hope someone could explain to a noob how to properly create Arc-Lighter hdpi. Thanks

Hi @Cencar ,

cd
mkdir .themes
cd Downloads/
git clone https://github.com/loichu/arc-theme-xfwm4-hidpi.git
cd ~/.themes
tar -xvzf ~/Downloads/arc-theme-xfwm4-hidpi/arc-theme-xfwm4-hidpi.tar.gz

then click to Bottom left corner and type
Appearance
select Style Arc-Dark
select Icons High-Contrast
change font size to 16 or 17 as needed

Optionally you may consider using Invert Colors extension in Firefox + shortcuts

the Settings Hardware Display Scale Custom <1 (.9 or .7) also worth a try
Edit: Firefox extension Eye-Able is even more useful.
