Your Guide to Using the Afterburner2 Template for Joomla


Afterburner2 is an experiment in how streamlined a Gantry Framework Template can be, whilst still being visually enticing and usable on a live site. Although many extras have been removed, styling for major elements, such as the Joomla core, is still abundant.

The template has a simple, CSS based dropdown menu system, module variations, multiple preset styles, configurable responsive modes, and advanced typography styling, whilst still maintaing a speed-centric and performance edge.

Speed and Optimization

Afterburner2 is a fully functional Gantry template, even with responsive capabilities. Therefore, speed and optimization developments are relative to the Gantry Framework and its offerings, versus a Joomla template more generally.

Afterburner2 + RokBooster Gantry + RokBooster
Requests 12 5 18 7
Time 428ms 342ms 555ms 375ms
Size 510KB 173KB 604KB 219KB

Requests: Requests are the number of items that are loaded on a page. Reducing the number of requests improves performance. With RokBooster enabled, which we recommend once you have finished development, the total requests are 5: 1 CSS, 1 Javascript, 1 Font, 1 Image and Text/HTML data; an incredibly low count.

Time: The time, in milliseconds, for the page to finish loading all requests. In local tests, the template with RokBooster enabled is about 1/3 of a second.

Size: The size, in kilobytes, of all requested item. Smaller file sizes lead to speedier loading. The necessary files have been optimized to reduce their overall footprint, for example, the logo is only 1.5KB, the only image file loaded by Afterburner2. With RokBooster enabled, the footprint is 173KB which is a significant reduction.

Responsive Layout

Afterburner2's responsive grid system is designed for desktop, tablet and smartphone systems, each with minor modifications to ensure compatibility in each mode.

We use the responsive layout based on Twitter's Bootstrap Framework, with its collection of utility classes, to provide a great degree of flexibility for a responsive design.

Label Description Layout Width Column Width
Smartphones Standard smartphones 480px and below 100% fluid
Smartphones to Tablets Larger smartphones and small tablets 767px and below 100% fluid
