This scroll margin is the default value that can be set for all content on a website. The default margin is the width of the scroll bar. You could choose a larger margin and see that the content is wider, or you could choose a smaller margin and see that the content is narrower.
There is no exact “rule” for how high the content should go, but the default is the width of the scroll bar. If you set a smaller margin, the content will shrink to fit the space you’ve set up for it. If you set a larger margin, the content will stretch to fill the space you’ve set up for it.
It seems like this default is fairly arbitrary, but it really really is just the default. There’s no point for a scroll bar to be wider than the content, because if you set the width of the scroll bar and the content to be the same, you’re basically making the content go all the way to the edge of the page.
Setting the width to the default, as in setting the scroll bar to 100% of the page width, is the best way to go about this. If you set the scroll bar to have a 100% height, the content will wrap to fit the width of the page. If the content doesn’t wrap to the page because there isn’t enough room, the scroll will drop to the bottom of your viewable area.
This is the exact same problem with the scrollbar in IE. The scrollbar defaults to being 100% of the viewable area, just like the IE scrollbar. To fix this, you can set the height of the scrollbar to anything you want, but the width of the scrollbar needs to be the same as the viewable area.
Scrollbars are great for getting content to sit next to each other without it wrapping. Like on a webpage with lots of content, you can see the scrollbar automatically adjust its height if there’s enough room. But on the other hand, you can’t have the scrollbar stay at the bottom of the viewable area. You can’t scroll down and down one page in your browser and not have the scrollbar jump down every time you scroll down one page.
The scrollbar is the most popular way of doing things. If you scroll down and down a page, you can see the scrollbar slide to the right of the page you were scroll-left.
I think the scrollbar is the most popular way of doing things. If you scroll down and down a page, you can see the scrollbar slide to the right of the page you were scroll-left.
The way your browser is displayed on your screen is quite the opposite. It displays only the scrollbar, not the scroll. As you scroll down, it switches to a different area. This means that a page that you scroll-left is never displayed on your screen.
It’s still hard to explain but scroll-margin-top is a feature of the scrollbar that’s enabled by default for most sites. It’s one of the most used features of the scrollbar. You can see a lot more detail about it here.
