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.

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.

p>Nested rows should include a set of columns that add up to the number of columns of it's parent. For example, two nested .span3 columns should be placed within a .span6.

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.

这时候作为一位卓越的班组长,咱们就要把班组中碰着的下场先自我子细机虑并提出一系列卓实用果的处置妄想,而后在向向导陈说,让向导来抉择哪一个妄想的正当性以及可行性最强。这一年来,自己子细做好各方面的使命。

<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.

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">

    </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.

咱们全组教师告竣共识,在同样艰深教育教学使掷中自动做到:以精确的倾向向导学生,以高尚的品格影响学生,以扎实的知识教育学生,以瘦弱的去世气愿望哺育学生。三、增强清静教育。

二是对于课后实习要精心妄想。四、坚持听课,从资深的老教师那边学到更好的教学措施,同时在网上搜查统一课程优异教师的课堂实录,散漫本班学生实际天气设定加倍适宜的教学妄想。

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:

  1. 主营业务
  2. 热点专题
  3. 商务合作

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) { ... }
