我有一些相對簡單的事情。我有一張應該顯示在網頁左側的圖片&它的高度應該是用戶的屏幕尺寸。將圖像調整到屏幕高度,但保持比例
我使用javascript將圖像大小調整爲用戶屏幕高度。但它並沒有調整它的大小。功能運行,但圖像大小不會改變。
有沒有辦法將圖像大小調整爲用戶屏幕高度&以保持透視(使寬度成比例)?

感謝您的答覆。但設置內聯css樣式也不會更改圖像高度。我能做些什麼來解決這個問題? – Mack
@Mack,嘗試刪除您的JavaScript並將@ dtbarne的樣式放入樣式表中。例如。 #midContainer img {height:100%;} – Dan
downvote的解釋? – dtbarne
