My site has nine content pages, each showing a two-volume data table. I need those tables to fit comfortably on single pages without forcing users to scroll sideways or hunt for split columns. At the top of the same layout sit three embedded YouTube clips; they currently overflow the design, so please resize the embeds but keep all three visible together—no carousel or hidden navigation, just three neatly proportioned videos in view. On the homepage I want a flat “Network+ Self Study Guide” button. When visitors click, they land on the guide that starts with an introduction followed by ten weekly sections. By default week 1 is active, yet whichever week a visitor selects should light up to show their current spot—for example, if they jump straight to week 3, that tab or link should highlight while all others remain neutral. In short: • Resize and embed all three videos cleanly on one page. • Reformat each two-volume table so the full content sits on a single page without side scroll. • Add a flat CTA button to the homepage that routes to the study-guide section. • Build week-by-week navigation so the active week highlights automatically, defaulting to week 1. Use straightforward HTML, CSS, and JavaScript (or a light framework if you prefer) so the solution stays easy for me to maintain. Once done, hand over the updated pages and any support files so I can drop them straight into the site.
