The article critiques the current state of HTML and the Document Object Model (DOM), arguing that they have become bloated and outdated, failing to meet the needs of modern web applications. It highlights the inefficiencies and complexities of working with the DOM and CSS, suggesting a need for rethinking these technologies to better align with contemporary development practices and user expectations. The author calls for a more streamlined and effective approach to web development that moves away from legacy constraints.

The article discusses the setHTML() method of the Element interface, which provides a way to safely parse and sanitize HTML strings before inserting them into the DOM. This method removes any XSS-unsafe elements and attributes, making it a recommended replacement for Element.innerHTML when handling untrusted content. It also highlights the importance of using a sanitizer configuration to define allowed elements and attributes.
