Mobile first

-

With Bootstrap 2, we added optional mobile friendly styles for key aspects of the framework. With Bootstrap 3, we've rewritten the project to be mobile friendly from the start. Instead of adding on optional mobile styles, they're baked right into the core. In fact, Bootstrap is mobile first. Mobile first styles can be found throughout the entire library instead of in separate files.

To ensure proper rendering and touch zooming, add the viewport meta tag to your <head>.

{% highlight html %} {% endhighlight %} -

You can disable zooming capabilities on mobile devices by adding user-scalable=no to the viewport meta tag. This disables zooming, meaning users are only able to scroll, and results in your site feeling a bit more like a native application. Overall we don't recommend this on every site, so use caution!

Responsive images

Images in Bootstrap 3 can be made responsive-friendly via the addition of the .img-responsive class. This applies max-width: 100%; and height: auto; to the image so that it scales nicely to the parent element.

Bootstrap sets basic global display, typography, and link styles. Specifically, we:

-
    -
  • Set background-color: #fff; on the body
    • -
  • Use the @font-family-base, @font-size-base, and @line-height-base attributes as our typographic base
    • -
  • Set the global link color via @link-color and apply link underlines only on :hover
    • -
-

These styles can be found within scaffolding.less.

Grid system

-
-

Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.

+ +
+

Grid system

-

Introduction

-

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:

-
    -
  • Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
    • -
  • Use rows to create horizontal groups of columns.
    • -
  • Content should be placed within columns, and only columns may be immediate children of rows.
    • -
  • Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
    • -
  • Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
    • -
  • Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
    • -
-

Look to the examples for applying these principles to your code.

Grids and full-width layouts

Folks looking to create fully fluid layouts (meaning your site stretches the entire width of the viewport) must wrap their grid content in a containing element with padding: 0 15px; to offset the margin: 0 -15px; used on .rows.

Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg- class is not present.
