Javascript顯示和CSS

2012-10-18 68 views

我不得不使用Javascript創建一個「假」天氣頁面。我的佈局掙扎，有幾個問題：Javascript顯示和CSS

  • 我什麼都試過，包括填充我上面的「H1」的稱號，但沒有任何工程。

  • 我想要天氣照片和信息顯示在盒子的中間（就像它在第0天一樣），但我無法做到這一點。

  • 您會不會推薦將我的.js文件分解爲不同的函數，或者可以將它全部整合到一個函數中。我想避免它令人困惑？

任何機會，你可以敲ip的http://www.JSFiddle.com/爲此？ –

你有沒有試過給h1標籤的CSS添加一個padding屬性？ –

不是.com，http://jsfiddle.net，不支持域名垃圾郵件發送者 –

Here你走了。使用padding屬性填充，你使用了spacercell td來顯示中間的東西，並且沒有一個js文件是好的。

編輯：修復了一些事情。您在css中使用.content選擇器而不是#content選擇器。 Here是更新後的版本。

首先，我想問你，你真的需要使用表標籤幾天嗎？我的意思是不能使用div標籤？因爲在表格標籤中，所有的內部標籤總是具有相對位置。

可以插入day0/DAY1等絕對位置標籤內div標籤，然後使用
divId.innerHTML = getDayTitle（I） （所有相應的方法）來設置文本，而不是通過JS生成整個表的。

其次，如果在未來，如果你改變文字的字體等，然後還表可能產生問題，因爲它總是使用「適合內容」類型的方法，因此TR大小可根據您的文字大小

div的使用增加標籤和它肯定會工作:)
