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.
.span3
columns should be placed within a .span6
.
<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.

<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>
The default and simple 940px-wide, centered layout for just about any website or page provided by a single <div class="container">
.
<body> <div class="container"> ... </div> </body>
<div class="container-fluid">
gives flexible page structure, min- and max-widths, and a left-hand sidebar. It's great for apps and docs.
<div class="container-fluid"> <div class="row-fluid"> <div class="span2"> <!--Sidebar content--> </div> <div class="span10"> <!--Body content--> </div> </div> </div>
Media queries allow for custom CSS based on a number of conditions—ratios, widths, display type, etc—but usually focuses around min-width
and max-width

“未来3-5年内,我希望在一家公司稳定下来好好积累沉淀,经济上把负债还清,同时调整一下自己的生活状态,之前一直在创业,几乎没怎么顾及生活。 这说明什么? 说明你抢占的市场越大,你舒服赚钱的可能性越小,所以滴滴这类公司虽然规模很大,但它总是处于焦虑之中。

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) { ... }

互联网最早做大的公司是百度,以搜索业务见长,腾讯在这方面竞争不过百度,所以才做了社交,后来才有了微信;网易没有搜索,也没有微信,但是开拓了游戏业务,也慢慢成为这个领域中的强势平台。故拉卡拉本次资产重组并不构成重大资产重组,也未造成公司近三年主营业务发生变更
创业路上还要重视合作,跟谁合作、怎么合作都是创业路上的必修课。 情绪在决策中扮演的角色是极其复杂的,将情感和理性简单的一分为二更是不正确的。
