What tool allows Web authors to create Web pages without typing the necessary HTML code?

A GUI HTML editor is specifically designed to allow web authors to create web pages through a graphical user interface without needing to write HTML code manually. These editors provide tools such as visual design interfaces, drag-and-drop features, and pre-built elements that make it easier for users to format text, insert images, and implement other web features visually. This is particularly beneficial for individuals who may not be familiar with coding, as they can focus on the design and content rather than the underlying code.

In contrast, a text editor is primarily used for writing and editing code directly, which requires knowledge of HTML or other programming languages to generate a website. A command line interface allows users to interact with the computer by typing commands, which is not appropriate for creating web pages in a user-friendly manner. A markup validator is a tool used to check for errors and validate the correctness of HTML code but does not assist in the creation process itself. Thus, the GUI HTML editor stands out as the most effective option for creating web pages without directly engaging with HTML coding.
