我有一個名爲containerdiv,其中包含多個子元素div。在這些孩子div s中,最上面的一個,名爲top_bar,有position: fixed,而其餘的其他人有position: relative。麻煩的是,具有相對定位的div與固定定位的div重疊。 jsfiddle概述了這個問題。我可以通過加入top:150px來解決這個問題,但這種感覺更像是一種黑客攻擊。有一個更好的方法嗎?具有固定位置和相對位置的重疊格子

這不是破解:當你修復一個元素的位置時,它會被有效地從文檔佈局中取出,並且不會影響其他元素(靜態或相對)的位置。當涉及從流動中移除時,它的行爲與位置類似:絕對。 – Terry

我之所以稱它爲黑客,是因爲我們可以說在某些情況下,固定條的高度可能會增加,重疊會再次發生。我正在尋找一個動態的解決方案,可以處理這些細節。 –

在這種情況下,您將不得不使用JS來規避您的問題:(1)使用JS來計算固定導航欄的總高度,然後將其應用爲頂部填充(即「頂部填充」),或基本位置「頂部」,到文檔的內容包裝。或者,(2)實際上是創建一個固定導航副本,一個靜態/相對定位,另一個固定定位和隱藏。我認爲這個實現有點複雜,但是,它的好處是它爲你的導航欄保留了空間而不需要重新計算高度。 – Terry

padding-top:120px;增加到containertop:0;top_bar到下面的div不疊加到topbar。
