我对 Twitter Bootstrap 和整个网格框架还是个新手，所以如果这看起来是一个非常菜鸟的问题，请多多包涵。
但这是我目前拥有的 in a jsFiddle 。

我想要实现的是在空白处的最后一个大红色框之后放置 2 个小框。我做了一些研究，我读到它需要在一行中嵌套一行，然后放置一列。但这似乎适用于跨度的非流体应用，即固定宽度。然而，我正在以百分比测量这些框，并且不确定如何继续嵌套这些行。有帮助吗？
最佳答案
有几种方法可以做到这一点。一种是这样嵌套它们: ( http://jsfiddle.net/rdTfe/ )
<div class="container-fluid">
<div class="row-fluid">
<div class="span12">
Red area here.
<div class="row-fluid">
<div class="span6">
Small box
</div>
<div class="span6">
Small box
</div>
</div>
</div>
</div>
</div>
但是，这将扩展红色容器本身。所以除非我误解了你想做什么，否则你真的不需要嵌套它们。 ( http://jsfiddle.net/rdTfe/1/ )
<div class="container-fluid">
<div class="row-fluid">
<div class="span12">
Red area here.
</div>
</div>
<div class="row-fluid">
<div class="span6">
Small box
</div>
<div class="span6">
Small box
</div>
</div>
</div>
以这种方式嵌套它们可确保所有红色框和其他较小框的左右边缘垂直对齐。
Bootstrap 3 更新
上面的例子可以这样写:http://jsfiddle.net/9wQ2M/10/
<div class="row">
<div class="col-md-12">
Red area here.
<div class="col-md-6">
Small box
</div>
<div class="col-md-6">
Small box
</div>
</div>
</div>
没有嵌套... http://jsfiddle.net/55z7p/3/
<div class="row">
<div class="col-md-12">
Red area here.
</div>
</div>
<div class="row">
<div class="col-md-6">

</div>
<div class="col-md-6">

关于html - Twitter Bootstrap 行嵌套，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12709905/
我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
我得到了一个包含嵌套链接的表单。编辑时链接字段为空的问题。这是我的表格:Editingkategori{:action=>'update',:id=>@konkurrancer.id})do|f|%>'Trackingurl',:style=>'width:500;'%>'Editkonkurrence'%>|我的konkurrencer模型:has_one:link我的链接模型:classLink我的konkurrancer编辑操作:defedit@konkurrancer=Konkurrancer.find(params[:id])@konkurrancer.link_attrib

在我的Controller中，我通过以下方式在我的index方法中支持HTML和JSON:respond_todo|format|format.htmlformat.json{renderjson:@user}end在浏览器中拉起它时，它会自然地以HTML呈现。但是，当我对/user资源进行内容类型为application/json的curl调用时(因为它是索引方法)，我仍然将HTML作为响应。如何获取JSON作为响应？我还需要说明什么？ 最佳答案 您应该将.json附加到请求的url，提供的格式在routes.rb的路径中定义。这
所以我在关注Railscast，我注意到在html.erb文件中，ruby代码有一个微弱的背景高亮效果，以区别于其他代码HTML文档。我知道Ryan使用TextMate。我正在使用SublimeText3。我怎样才能达到同样的效果？谢谢! 最佳答案 为SublimeText安装ERB包。假设您安装了SublimeText包管理器*，只需点击cmd+shift+P即可获得命令菜单，然后键入installpackage并选择PackageControl:InstallPackage获取包管理器菜单。在该菜单中，键入ERB并在看到包时选择
下面例子中的Nested和Child有什么区别？是否只是同一事物的不同语法？classParentclassNested...endendclassChild 最佳答案 不，它们是不同的。嵌套:Computer之外的“Processor”类只能作为Computer::Processor访问。嵌套为内部类(namespace)提供上下文。对于ruby解释器Computer和Computer::Processor只是两个独立的类。classComputerclassProcessor#Tocreateanobjectforthisc
我的假设是moduleAmoduleBendend和moduleA::Bend是一样的。我能够从thisblog找到解决方案,thisSOthread和andthisSOthread.为什么以及什么时候应该更喜欢紧凑语法A::B而不是另一个，因为它显然有一个缺点？我有一种直觉，它可能与性能有关，因为在更多命名空间中查找常量需要更多计算。但是我无法通过对普通类进行基准测试来验证这一点。 最佳答案 这两种写作方法经常被混淆。首先要说的是，据我所知，没有可衡量的性能差异。(在下面的书面示例中不断查找)最明显的区别，可能也是最著名的，是你的
我正在使用Rails构建一个简单的聊天应用程序。当用户输入url时，我希望将其输出为html链接(即“url”)。我想知道在Ruby中是否有任何库或众所周知的方法可以做到这一点。如果没有，我有一些不错的正则表达式示例代码可以使用... 最佳答案 查看auto_linkRails提供的辅助方法。这会将所有URL和电子邮件地址变成可点击的链接(htmlanchor标记)。这是文档中的代码示例。auto_link("Gotohttp://www.rubyonrails.organdsayhellotodavid@loudthinking.
