情节：在构建优惠券网站时,我意识到他们可以是不是页面独有的内容,但应该在< main>< article>内使用. ..here ..< /冠词GT;< /主取代.
问题：仅仅因为w3schools声明：
The content inside the element should be unique to the
document. It should not contain any content that is repeated across
documents.
但我有内容将在文章内.例如,每次例如可以通过输入其代码来使用优惠券,但只能通过转到登录页面来激活交易.
这将在我将发布的每个“优惠券”帖子中重复出现.
所以我现在尝试使用的是.
<main><article><main>Unique content</main> <aside>A coupon can be used by entering its code but a deal can only be activated by going to landing page</aside></article></main>
但是又一次：
Note: There must not be more than one <main> element in a document. The <main> element must NOT be a descendent of an <article>,<aside>,<footer>,<header>,or <nav> element.
