One difference from Drupal 7 is that block content can no longer be directly edited by selecting an edit link from a context menu or by clicking on an Edit button on the Block layout page. Drupal 8 introduced a new section known as the Custom block library.

We can navigate to the Custom block library by directly entering /admin/structure/block/block-content, or by using the Admin toolbar and clicking on Structure | Block layout and then selecting the Custom block library tab.

The Custom block library page consists of two sub-sections:

• The Blocks tab displays all custom blocks that have been created. Each block is listed by Block description, Block type, and last updated date
• The Block types tab displays all block types that have been created. Each block type is listed by the type and description

We will take a closer look at each section beginning with the Blocks tab. It is this section where we will be able to Edit and Delete custom blocks that have been created.

The custom block that we created earlier is displayed in the list of blocks. Located next to each block is the OPERATIONS field, which allows us to both Edit as well as Delete blocks that have been created.
