當我使用觸控板滾動時，工具欄和主窗口之間有一個白色的間隙（在這個頂部標題上方）。你可以在我附上的圖片中看到它。只有在使用觸控板（不是鼠標）滾動到窗口底部的頂部或底部時纔會出現此間隙。如何設置超出「正常」窗口的背景顏色？當滾動到頂部或底部時操作瀏覽器窗口的顏色
//當我不滾動：

嗯..你能告訴我們你是怎麼做到的嗎？一些代碼，以便我們可以找到在哪裏幫助你？ – Sinstein
當然，我把它添加到問題。我是htmland css的新手。網頁設計師是否使用在線工具分享代碼？用代碼附上鍊接會更乾淨。 – brumbrum
是的。請參閱https://blog.stackoverflow.com/2014/09/introducing-runnable-javascript-css-and-html-code-snippets/。 – Sinstein
