尽管命令行比较工具会将其输出显示为一个又一个比较（在单个垂直列/控制台窗口中），但我所知道的所有 GUI 比较工具都倾向于在两个窗格、分屏 UI 中显示比较。

How usable is a document which uses <ins> and <del>, compared to seeing the deltas in a two-pane split-screen diff viewer?
Although a command-line diff tool will show its output as one diff after another (in a single vertical column / console window), all the GUI diff tools that I know of tend to show diffs in a two-pane, split-screen UI.
I'd like it if <ins> and <del> were usable but it worries me that, instead, two-pane split-screen diff viewers seem to be the norm.
Secondly, have you seen any sites or software which use the <ins> and <del> elements to show revisions, and if so would you please point them out to me? I'd like to see examples of their being used (in order to make a subjective opinion of how usable they are).

例如，Trac 在其差异页面上使用此功能，甚至在两窗格视图中也是如此。 您可以在此处查看示例。
Trac uses this for example on its diff pages and does that even in a two-pane view. You can see an example here.
Stackoverflow 在其编辑历史页面中显示内联差异。 因此，如果您对它的工作原理感到满意，那么可以肯定地说它相当有用。
; & 不使用元素，使用带有类的标签，但使用元素。 & 可以使用元素来代替。Stackoverflow shows inline diffs in the its edit history pages. So, if you're comfortable with how that works, its safe to say that its fairly usable.

<ins> & <del>elements aren't used,<span>tags with a class are, but<ins> & <del>elements could have been used instead.
