AWS, JavaScript, React - Deploy Web Apps on the Cloud - JavaScript Project 2 - Completion

The video tutorial guides viewers through creating a web page layout using HTML and CSS. It starts with setting up a container with center alignment, followed by adding a header. The main focus is on creating a division for a preview image, styled with CSS, and inserting a default image. The tutorial then covers adding a code block for thumbnails, each with a JavaScript onmouseover event to change the preview image source. Finally, it instructs on saving and previewing the completed script in a web browser.
