What is the main purpose of a GUI HTML editor?

The main purpose of a GUI HTML editor is to enable web authors to create web pages without the need to manually type HTML code. These editors provide a visual interface that allows users to drag and drop elements, edit content in a WYSIWYG (What You See Is What You Get) format, and manipulate page layout intuitively. This makes it accessible for those who may not have a strong coding background or are looking for a quicker way to design their web pages.

While coding-only approaches would typically involve writing and debugging HTML directly, GUI HTML editors abstract much of this complexity, allowing users to focus on design and content rather than the intricacies of HTML syntax. The other options pertain to aspects of web development that are not the primary focus of GUI HTML editors. For example, managing server resources and optimizing existing HTML code relate to broader web development practices rather than the specific function of creating web pages visually.
