Your texts, images, buttons, and other block contents are referred to as your site’s elements. All elements have their own placeholders — an area they occupy in a block. You can also enrich the look of your blocks by adding additional elements to them — more buttons, lists, dividers, or social icons:

Each item has its own settings, but there are basic actions that can be applied universally — you can copy, delete or move them within the block they are added to.

Besides, elements are usually gathered in columns for quick customization. With the help of columns, you can easily adjust your content alignment or change the background in this specific part of the block. See the article Managing elements to learn more about the columns and the elements they contain.
