Turn on responsive CSS in your project by including the proper meta tag and additional stylesheet within the <head>
of your document. If you've compiled Bootstrap from the Customize page, you need only include the meta tag.
<meta name="viewport" content="width=device-width, initial-scale=1.0"> <link href="assets/css/bootstrap-responsive.css" rel="stylesheet">
Heads up! Bootstrap doesn't include responsive features by default at this time as not everything needs to be responsive. Instead of encouraging developers to remove this feature, we figure it best to enable it as needed.
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
.
Use media queries responsibly and only as a start to your mobile audiences. For larger projects, do consider dedicated code bases and not layers of media queries.
Bootstrap supports a handful of media queries in a single file to help make your projects more appropriate on different devices and screen resolutions. Here's what's included:
Label | Layout width | Column width | Gutter width |
---|---|---|---|
Large display | 1200px and up | 70px | 30px |
Default | 980px and up | 60px | 20px |
Portrait tablets | 768px and above | 42px | 20px |
Phones to tablets | 767px and below | Fluid columns, no fixed widths | |
Phones | 480px and below | Fluid columns, no fixed widths |
/* Large desktop */ @media (min-width: 1200px) { ... } /* Portrait tablet to landscape and desktop */ @media (min-width: 768px) and (max-width: 979px) { ... } /* Landscape phone to portrait tablet */ @media (max-width: 767px) { ... } /* Landscape phones and down */ @media (max-width: 480px) { ... }
For faster mobile-friendly development, use these utility classes for showing and hiding content by device. Below is a table of the available classes and their effect on a given media query layout (labeled by device). They can be found in responsive.less
.
Class | Phones 767px and below | Tablets 979px to 768px | Desktops Default |
---|---|---|---|
.visible-phone |
Visible | Hidden | Hidden |
.visible-tablet |
Hidden | Visible | Hidden |
.visible-desktop |
Hidden | Hidden | Visible |
.hidden-phone |
Hidden | Visible | Visible |
.hidden-tablet |
Visible | Hidden | Visible |
.hidden-desktop |
Visible | Visible | Hidden |
Use on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities should not be used with tables, and as such are not supported.
Resize your browser or load on different devices to test the above classes.
Green checkmarks indicate that class is visible in your current viewport.
