与 header
和 nav
类似,footer
元素也具有语义化的特性,可以让辅助工具快速定位到它。它位于页面底部,用于呈现版权信息或者相关文档链接。
--instructions--
Camper Cat 的忍者训练页面进展顺利。请将他在页面底部呈现版权信息的 div
元素更改为 footer
元素。
--hints--
应存在一个 footer
标签。
assert($('footer').length == 1);
不应存在 div
标签。
assert($('div').length == 0);
确保 footer
元素有结束标签。
assert(code.match(/<footer>\s*© 2018 Camper Cat\s*<\/footer>/g));
