爲什麼標籤/ div（我試過兩種）不居中？

u能張貼渲染代碼和CSS – Sowmya

似乎是工作。檢查小提琴：http://jsfiddle.net/2c37L/ –

這意味着什麼寬度？「選項」和「塊」都有指定的寬度。您期望使用哪個寬度？目前該地區的寬度是多少？ – webnoob

變化：

<div style="text-align:center; color: #4E1329; font-size: smaller; float:none"> 
    you can search by acc no and username 
</div>

到

<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller; display:inline;"> 
    you can search by acc no and username 
</div>

注意：您可能還需要考慮使用CSS類，而不是內聯樣式。

編輯：好了看到你的編輯後，你的類block需要設置一個寬度。爲了使文本能夠居中，它需要100％的寬度。爲了100％的寬度工作，你需要一個父寬度。如果塊有寬度，請張貼CSS。

編輯 - 最後修訂：

display:inline現在是混淆了。這和float:none;需要刪除。

<div style="width: 100%; text-align:center; color: #4E1329; font-size: smaller;"> 
    you can search by acc no and username 
</div>

仍然一樣。 – sprocket12

只需進行編輯，再次嘗試第二部分代碼。 – webnoob

還沒有... – sprocket12

似乎它與周圍的DIV做。如果你用一個固定的方式在它周圍放置一個div，一切似乎都很好。

HTML：

<div style="width: 300px; border: 1px solid red;"> 
    <div style="padding: 12px 13px 0px 12px;"> 
     <span class="label">Search :</span> 
     <input name="ctl00$MainContentPlaceHolder$txtSearch" type="text" id="MainContentPlaceHolder_txtSearch" class="textbox" Size="16" /> 
     <input type="submit" name="ctl00$MainContentPlaceHolder$btnSearch" value="Search" id="MainContentPlaceHolder_btnSearch" class="button" style="float: right" /> 
    </div> 
    <div style="text-align:center; color: #4E1329; font-size: smaller; float:none"> 
     you can search by acc no and username 
    </div> 
</div>

說實話，它周圍的div已經有一個固定的寬度。（在CSS中） – sprocket12

兩者的div是分開的，上述div有填充。嘗試添加填充到以下div也像

style ="padding: 12px 13px 0px 12px;text-align:center;"

我希望這會工作。

你的Div有一個內聯CSS，它說你的div是display:inline。這是出於什麼特殊原因？因爲如果你刪除相同的，你會發現Div變成中心對齊。
