Blocks are small, reusable pieces of content. The placement of blocks – on which page(s) and where on the page – is centrally managed by Trinity Communications and Trinity Web Support, but the content can be modified by site editors, with a few exceptions. A list of blocks which can be updated by site editors can be found in the Block Library. A link to this page can be found in the Shortcuts menu.
Please see the Managing blocks how-to for full instructions.
