The standard Dreamweaver workspace is where you create and edit your web pages. It includes the document area and panels such as Files, Insert, and CSS Designer. You can move the panels around the make the workspace more comfortable for you.

A hamburger menu is an icon with three horizontal lines. When you click it, it opens a menu with more options. It is often used on websites and mobile apps to save space.

A tab group is a set of panels grouped together in one area. You can switch between them by clicking their tabs. For example, Files and Insert can be in the same tab group.

The Image option lets you choose an image file and add it to your web page. Dreamweaver creates the <img> tag for you, so you do not have to type the code yourself.
