The Bootstrap Grid:

Bootstrap calls this “Scaffolding:”

<div class="row">

<div class="span4">...</div>

<div class="span8">...</div>

</div>

Div elements are used to build rows and columns.Widths and Margins controlled by the framework.Optionally responsive using CSS media queries.

The Bootstrap Grid:Commonly 12 columns by 60px (static)Modified for BBS to 16 columns by 40px (static)Can “nest” grids (like tables or divs)

Optionally:Flexible-width between 724px and 1170pxCan adapt layout (hide/show/resize) based on deviceCan reflow content on resize (or orientation change)

Responsive = Increased Complexity

Bootstrap Base CSS:Nice-looking default styles for common elements, normalizing most browser and OS rendering errata.

Typography (headlines, body copy, callouts, etc.)Tabular Data (striping, hover, row colors, context)Images (borders, frames, shape masking) Forms (input add-ons, help text, validation, selects)Buttons (basic types, states, size options & icons)

Bootstrap Base CSS:Table Example:

<table class="table table-striped">

…

</table>

Result:

Bootstrap Base CSS:Input example:

<div class="input-prepend input-append">

<span class="add-on">$</span>

<input class="span2" id="appendedPrependedInput" type="text">

<span class="add-on">.00</span>

</div>

Next Steps: Testing & Review

Static Components to Test:twitter.github.com/bootstrap/components.html link :

Button Dropdowns (Parent/Child listings)

Thumbnails (search results)

Alerts & Progress bars

Dynamic Components to Test:twitter.github.com/bootstrap/javascript.html link

Modal popups

Tab panels

Collapsible content blocks

“Sandboxed” Test Opportunities:

Email and Ad Landing Pages

BBS Style Guide

FSBO Landing Page & sales flow prototyping

L&F State and Property-type pages

Potential Problems

Potential Problems

Introduces another 3rd party dependency

Potential conflicts with existing styles

Limited benefit on very complex pages

Version lock-in for JavaScript Components

Additional QA load for responsive sites
