Get the lowdown on the key pieces of Bootstrap's infrastructure, including our approach to better, faster, stronger web development.
HTML5 doctype
Bootstrap makes use of certain HTML elements and CSS properties that require the use of the HTML5 doctype. Include it at the beginning of all your projects.
{% highlight html %}
<html lang="en"> ... </html> {% endhighlight %}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!
{% highlight html %}
{% endhighlight %}Typography and links
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-baseattributes as our typographic base - Set the global link color via
@link-colorand apply link underlines only on:hover
These styles can be found within scaffolding.less.
Normalize
For improved cross-browser rendering, we use Normalize.css to correct small inconsistencies across browsers and devices.
