如何更改此CSS代碼以獲取所需佈局

以下是我的CSS代碼。有了這段代碼，我得到了100px左右寬度的菜單和700px寬度的中間內容。（總寬度爲900px。）但是，我的要求是寬度爲100px的左右側邊欄和800px寬度的中間內容。（總寬1000px。）如何改變下面的CSS代碼來做到這一點？我盡力了，但是在改變數值的時候會變得混亂起來。如何更改此CSS代碼以獲取所需佈局

HTML？..檢出jsfiddle（jsfiddle.net） - 你可以複製你的問題。 –

沒有相應的HTML確實很難協助。 –

好的，添加了html。 –

試試這個

div#container { 
width: 1000px; 
margin: 0 auto;}

希望這將有助於！或回覆我回復。

你應該爲這個問題提供的HTML代碼了。可能是你沒有妥善放置你的網頁上的內容。因此，如果您也在這裏發佈HTML文件，很容易判斷。
