直到现在我知道<a>
你可以在里面放置一个<span>
完美的HTML Validate
但是其他标签呢:-div, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video
等等
他们是否有任何关于选择锚内标签的规范?
