You can publish whatever you want in the Offcanvas Section. It can be any module or particle.
By default, the available module positions are offcanvas-a and offcanvas-b but you can add as many module positions as you want from the Layout Manager.
You can also add the hidden-phone module class suffix to your modules so they do not appear in the Offcanvas Section when the site is loaded on a mobile device.
General Design: TAO is a circular sculpture in the shape of the TAO sign. It is comprised of thousands of small curved metal (or glass) scales, which move gently in the wind, or are moved by water dripping down from the top of the frame.
