The default grid system provided in Bootstrap utilizes 12 columns that render out at widths of 724px, 940px (default without responsive CSS included), and 1170px. Below 767px viewports, the columns become fluid and stack vertically.
<div class="row"> <div class="span4">...</div> <div class="span8">...</div> </div>
As shown here, a basic layout can be created with two "columns", each spanning a number of the 12 foundational columns we defined as part of our grid system.
<div class="row"> <div class="span4">...</div> <div class="span4 offset4">...</div> </div>
With the static (non-fluid) grid system in Bootstrap, nesting is easy. To nest your content, just add a new .row
and set of .span*
columns within an existing .span*
column.

<div class="row"> <div class="span6"> Level 1 column <div class="row"> <div class="span3">Level 2</div> <div class="span3">Level 2</div> </div> </div> </div>
The fluid grid system uses percents for column widths instead of fixed pixels. It also has the same responsive variations as our fixed grid system, ensuring proper proportions for key screen resolutions and devices.
我相信如果我们用一两年的时间,成为拥有巨大影响力的品牌和有几百万、上千万有深度价值观认同的用户群的话,我们一定可以在这个基础上长出非常可怕的商业模式来。今天我们继续分享第二个话题:内容公司的护城河是什么。
<div class="row-fluid"> <div class="span4">...</div> <div class="span8">...</div> </div>
Nesting with fluid grids is a bit different: the number of nested columns doesn't need to match the parent. Instead, your columns are reset at each level because each row takes up 100% of the parent column.
<div class="row-fluid"> <div class="span12"> Level 1 of column <div class="row-fluid"> <div class="span6">Level 2</div> <div class="span6">Level 2</div> </div> </div> </div>

Built into Bootstrap are a handful of variables for customizing the default 940px grid system, documented above. All variables for the grid are stored in variables.less.
Modifying the grid means changing the three @grid*
variables and recompiling Bootstrap. Change the grid variables in variables.less and use one of the 3岁男童掉下水井被冲走已7天,“窨井之殇”如何防范?. If you're adding more columns, be sure to add the CSS for those in grid.less.

Bootstrap doesn't automatically include these media queries, but understanding and adding them is very easy and requires minimal setup. You have a few options for including the responsive features of Bootstrap:
Why not just include it? Truth be told, not everything needs to be responsive. Instead of encouraging developers to remove this feature, we figure it best to enable it.
/* Landscape phones and down */ @media (max-width: 480px) { ... } /* Landscape phone to portrait tablet */ @media (max-width: 767px) { ... } /* Portrait tablet to landscape and desktop */ @media (min-width: 768px) and (max-width: 979px) { ... } /* Large desktop */ @media (min-width: 1200px) { ... }

我觉得创业者必须要思考这几个问题: 首先,弄清楚你的媒体本质属性是什么,你面对的人群是什么,你的用户画像是什么。 共享单车在中国发展很快,在短短半年光景里,ofo走出了校园,摩拜单车走出了北上广深,而且越来越多的地域性的共享单车创业者开始涌现出来。
李丰:回到另外一个问题,你认为原来内容创作专业技能持有者在定价中是不合理的? 左志坚:因为他们是国有企业的一部分,是价值洼地,所以说这些人出来后,投资他们的话肯定是很值得的,因为原来就处于一个价值被高度低估的情况。所以王小川就说,我比李彦宏技术好,但是他比我命好。
