The author argues that traditional web components, particularly those using Shadow DOM, are unsuitable for marketing websites. They highlight how these components typically rely on JavaScript, which can hinder accessibility and performance on lower-powered devices with slow internet connections. Instead, the author suggests using an HTML Web Component architecture that minimizes JavaScript usage and embraces progressive enhancement to improve user experience. The concept of CSS Web Components is introduced as a solution that eliminates the need for JavaScript altogether. By leveraging CSS, the author demonstrates how to create interactive components solely with HTML and CSS. For instance, a swimlane component can be styled and modified using attribute selectors, allowing for layout changes without any script. This method simplifies design systems by utilizing standard HTML elements styled with custom attributes, reducing complexity while maintaining functionality. The author envisions a broad application of this approach for various components in marketing sites. By focusing on CSS capabilities, such as cascade layers, container queries, and CSS variables, designers can create flexible and responsive components without additional JavaScript dependencies. The article presents a compelling case for rethinking component architecture in a way that prioritizes performance and accessibility, especially for marketing platforms.
