The navbar, "new" badge, hero banner, and (slightly) rounded colorful buttons are all individually similar to how you often see those components used in Bootstrap. But in general and in one word, I think it's padding. Most modern design systems spread things out a good bit, and we see that in the navbar items and in the space around the hero. In total they are showing 6 links, 3 sentences, and 2 buttons, and are taking up a full screen. That's not something you'd see on a 2010 website.
