無効なフロート: 左、助けてください! _html/css_WEB-ITnose

是这样的 在内容页面我分两列，一列宽190px，一列宽760px；都没有padding或者是margin，总的页面宽度是950.在大的content里我加了float：left；可是并不管用，二者并不在同一行，而是上下两行。我缩短了760的宽度仍然不管用，求经验人士解答。

你把整个代码贴出来吧，这样说不清.

谢谢您了！

在呢！

嫌な意思、私も初級者です！

前に提示した時間に候人要我出完整代コード来，その後很快解解！
人難、就是多人想、句句不清、一大コード又何人人意看なし。
您も在吗?麻烦您看看吧

引用 1 楼チャットの返:
你管理全体代コード贴出吧、このような肨不清。

.con_right {    float: left;}

试一试

不管用啊！
}

试一试

con-left 你不是应该给它一个float:left;吗?
弄明你页面DIV的层次关系啊

con-left都没给 而是给了 子容器フロート:左;  

当然完了 .con_right も必要です

我都给了。  

当然了 .con_right你也要给一下

高手出现吧！！！！ 神啊

OK 試してください .con-right{width:760px;margin-left:0px;  float:right }

はこれではないですか?

知道你打算问什么关键内容，提问明確吧

不要给.con{ width:950px; margin-top:5px;}
定義、削除試行を参照。可能な場合は、さらに他のものを参照してください。おそらく視聴者の問題です。

試読を参照してください。 lt;div クラス='コン'> 950px、ただし、4814bfa1e02679b3bc83909638e97dd0 ここ、width=190px、

この幅は変更できません。

.con-left{width:300px; に変更できます。 高さ: 220ピクセル; float:left;} -----300px

または .con-left{width:100%; 高さ: 220ピクセル; float:left;} ----- 100%

float应该放在两个子div中，不是放在父div
