我从未见过<base> HTML标签实际上在任何地方使用。它的使用是否存在意味着我应该避免使用的陷阱?

事实上，我从未注意到它在现代生产站点(或任何站点)上使用过，这让我对它持怀疑态度，尽管它似乎在简化我站点上的链接方面有有用的应用程序。

Edit

After using the base tag for a few weeks, I did end up finding some major gotchas with using the base tag that make it much less desirable than it first appeared. Essentially, the changes to href='#topic' and href='' under the base tag are very incompatible with their default behavior, and this change from the default behavior could easily make third party libraries outside of your control very unreliable in unexpected ways, since they will logically depend on the default behavior. Often the changes are subtle and lead to not-immediately-obvious problems when dealing with a large codebase. I have since created an answer detailing the issues that I experienced below. So test the link results for yourself before you commit to a widespread deployment of <base>, is my new advice!
