site-content は、メニューを除くすべての幅を取得しました (そのため、#site-content{margin:0 0 260px 0})。#site-content には、固定幅 (740px) の div .site-content が含まれています。これは #site-content の中心にあります (.site-content{width:740px;margin:auto;} の理由)。.site-content には記事が含まれており、次の記事の直後にスペースが必要です。そのため、両方ともクリアを使用しましたが、メニューの後に次の記事を取得するため、すべてのフロート (メニューフロート) をクリアします。解決策をお願いします!
