A modern, elegant, and versatile theme for Beamer.
The theme’s implementation is heavily inspired from the Metropolis theme. Most options from Metropolis have been ported to Trigon in order to improve customization and ease-of-use. Trigon also includes different styles and layouts for the main title page, the section page and the default slide background.
The theme can be found on gitlab and its stable version is available on CTAN and is part of TexLive and MikTex 2021.
Please see the manual for all the customization options.
