Bootstrap is ‘mobile-first’ front end framework developed by a couple of engineers at Twitter (hence the name), it was originally designed to help provide some consistency across tools the guys were building internally. Since its first public (open source) release in 2011 (see the blog post here) it has found huge popularity among web developers for its ease of use and feature set, and in 2012 was the most popular project on GitHub. that allows for developing websites and custom applications that are cross-browser and cross-device compatible (responsive). Some of the key features of Twitter Bootstrap are:

Responsive design Base CSS For Typography, code, Tables, Forms, Buttons
Web UI Component Dropdowns, Buttons, Navigation menu, Labels, Breadrumbs, Pagination, Thumbnails, Alerts, Progress bars
JavaScript plugins Modal, Dropdown, Scrollspy, Tab, Tooltip, Popover, Alert, Button, Collapse, Carousel and Typehead
Built on LESS A CSS grid system for designing adaptive websites
Cross platform Ensures that the output is consistent across platforms & browsers
Integration Simple, fast and easy to work with existing sites
Compatibility Takes into account the future design & development standards e.g. HTML5 & CSS3
Open Source Allows developers to participate and add their contribution to be used by other bootstrap developers

They should add “Everything” to the “What is the main reason for your rating” This is the best theme out there and it’s really cheap! Looks simple but it has a lot of in depth and good features! This theme is the definition of awesomeness.

This is such an awesome and versatile theme! Out of the box it looks so professional and well thought out. Best PHPBB3 theme we’ve used. It is also highly customizable, and you can easily customize it to your needs. Support is TOP notch. Any issues or even general questions have been resolved via their forum in a matter of minutes. Also lots of MODS available and some of the premium ones are really worth it.

The rating drop-down box only allows you to select one reason for rating 5 stars. In reality it is all of them. This is a fantastic theme built by someone who knows what they are doing.

Dave is A+ developer. If you are looking for a forum template, you won’t find better than his in themeforest. His is the best! I’m using FLatBoots template and I love it. I ordered customization and all set ups from him, and he is the best in what he does. Dramabuzz.com Website was up and ready under 4 hours. Since I’m a complete newbie in website development, I keep bugging him with questions everyday Sorry Dave :)) And he always answers my questions and explains everything. The support is A+ for this template!

First and foremost, this simple yet modern and clean design is what sold me, but the reason behind the five stars is it’s designer – Dave. For a few months now, we have been working back and forth in order to customize and finalize our website. Dave has been such a godsend and amazing part of that whole process. Great open communication, great after-service, so patient and understanding, and just an awesome guy in general. I’d recommend this theme as well as any SiteSplat products, hands down!

Everything – design quality, feature availability, flexibility, customer support, bug-support, customizability, code quality, documentation quality…. and friendly communication. I have not tasted everthing what stands above, but when you take a step inside the supportforum you’ll see that everything is true. Thx Dave for a piece of code that makes so much fun!

To all future buyers, I come around since I got myself Flatboots and want to give a boost to Dave’ sales for the following reasons. - Access to a great community with plenty of MODS available for FLATBOOTS - Premium Mods that will rock your forums - Super fast and friendly support (I believe Dave is an alien, he doesn’t sleep) - yet my forum is not fully launched, I receive a loads of positive feedbacks about it and from forum owners too. Those $16 will be the best purchase you will ever made for a forum style.

This is not just a skin, it’s a perfectly polished product with a great support forum and additional modules. Feels even a bit like a new engine. 5 stars from me!

Its the perfect theme to start customising your forums! The addons, the way the theme is built, the support, the mod support ( they have made styles for the most popular mods to match the theme, how cool is this?!), the topic loader widget, everything about it, Couldn’t be easier to work with! Absolutely love it!

Complete newbie to PHP and developing Website Forums. This Theme looks clean, professional, and it just WORKS. I had one question/concern after a few days of using the Product and reached out to the Developer, Themesplat aka Dave, and he answered my question within a few hours and helped me resolve the issue. And prepared a fix that would help others who may encounter this issue. Great Product, Great Developer, Great Support. BUY THIS! You won’t be sorry

Absolutely perfect. No competition both in&out of themeforest. This stamps on all other designs I hav seen. ONE SIMPLE STATEMENT. Buy it or you’ll regret not doing so.

Support for this item is absolutely amazing. Extremely easy to set up the style, and if you have any issues it’s incredibly easy to get assistance. The theme is also exactly what I was looking for. Original. There are not many other themes like this out there, and it really grabbed my attention. Everyone who I’ve shown the forum to so far also loves it. The quality and customization availability is fantastic. MOD’s for the style are also regularly updated and released, which makes everything even better. Keep up the great work. Much appreciated.
