Gridbox is Faster Than Ever. Core Performance Improvements

Core Performance Improvements

We are always looking for performance solutions for Gridbox sites. During the last weeks, we have been working on improving the Gridbox core. It's time to introduce Joomla website builder Gridbox 2.12.4 with performance improvements up to 10x. Gridbox is faster than ever!

Performance Improvements of Joomla Website Builder Gridbox

Gridbox CSS File Compressed Up To 10x

Gridbox is a huge system that includes a really large number of components and website building tools - pages, plugins, fields, apps, eCommerce, etc. All these components include their own CSS styles. The CSS stylesheet of the Gridbox CSS files increased together with adding new options and features. We were forced to find a way to reduce the CSS and get the best performance for sites based on Gridbox.

After a long and painstaking work of reviewing each file, we achieved first-class results - we managed to reduce the size of the CSS up to 10 times. What have we done?

Smaller CSS

gridbox.css file was divided into a hundred small CSS files. In Gridbox 2.12.4 each Gridbox plugin comes with its own CSS file.

Gridbox.CSS Divided Into Smaller Ones - Performance Improvements of Joomla Website Builder Gridbox

Only Used CSS

Due to the fact that we have divided the gridbox.css file into hundreds of small CSS files, in Gridbox 2.12.4 page loads only used and necessary CSS styles. This is an incredible improvement that significantly reduces loaded CSS file size.

Global Library CSS

In Gridbox 2.12.4, we also made improvements and significantly reduced the global-library.css file. In the same way, as for the gridbox.css, the global-library.css file has been divided. As a result, page loads only used CSS element styles from the Global Library.

Inline CSS Styles

All necessary CSS styles are displayed inline, directly in the HTML. This technique reduces additional requests and speeds up page loading.

Mobile Optimized

One of the biggest improvements in reducing CSS is optimizing generated stylesheets for mobile devices.

Gridbox Performance Comparison

We can talk for a long time about the work done to improve performance. But it's better to look once. We have formed a comparative table of Gridbox performance to show you the results of our experiment. Here you can see the comparison criteria and the result of the performance gain. Let's compare!

The process of improving performance is endless, there is no limit to perfection! We will always look for ways to achieve excellence and provide high-quality optimized solutions. But also don't forget that a lot depends on you!

To get high-performing websites, you need to change the way you build websites! Hundreds of factors affect website performance. Use CDN for ready-made sites, start using local fonts instead of loading Google Fonts, create your own icons library with only necessary icons, etc. All this is possible with Gridbox. Creating high-performance sites is more than enabling a few toggle buttons. Start right now!
