CS50 Business - Lecture 6 - Weaving the Web (live, unedited) | CS50

The lecture introduces HTML, CSS, and JavaScript as tools for structuring, styling, and dynamically controlling web pages. HTML provides the structure and layout, while CSS handles aesthetics like fonts and spacing. JavaScript enables dynamic content updates and user experience enhancements. The lecture covers HTML tags, attributes, and semantic elements, CSS properties, selectors, and frameworks like Bootstrap. It also explores JavaScript's event-driven programming model, demonstrating how to manipulate the DOM and create interactive elements. Examples include creating a basic webpage, styling links, validating forms, and implementing autocomplete functionality. The lecture emphasizes the importance of client-side validation for usability while cautioning against its use as a sole security measure.
