html - 有没有办法在 Rails 中的表单上左对齐？

Question

请在此 URL 中引用该元素

solanosprinklers.net

我能够通过使用 :style =>"margin-left:-30%"使表单在跨度内居中

我使用了负边距，因为坦率地说，这是唯一最终起作用的方法。现在它在全屏上看起来不错，但是一旦它折叠到平板电脑和手机分辨率，文本字段就会超出“范围”。我需要帮助才能正确执行此操作。

另外，我怎样才能去掉“发送”按钮后面的灰色背景？

表单布局.....\layouts\indexform

<%= form_for @customer, :html => { :class => 'form-horizontal',:style =>'margin-left:-30%'} do |f| %>

Answer 1

我检查了网址。试试这个:

<div class="">
<%= f.submit "Send", :class => 'btn btn-primary',:style => "background:green" %>

</div>

只需将 class="form-actions"更新为 class=""

然后:

<div class="">
<%= f.submit "Send", :class => 'btn btn-primary',:style => "background:green;position:absolute;left=300px;" %>

</div>
