SFUMATO Layout Framework
Scalable web pages made easy.
Traditional responsive websites only look great at two or three screen widths.
Websites that use SFUMATO zoom like a PDF, can stop zooming at a maximum width, and are optimized for mobile. FINALLY, developers can easily create responsive, scalable, near pixel-perfect layouts.
The SFUMATO layout framework only uses SCSS for its complete feature-set. Resize your browser window to see it in action!
Visitors love it.
Sites are fully scalable, like a PDF, including mobile layouts, in most web browsers. It just "looks right" on every screen. And web apps are more accessible for people with disabilities.
SFUMATO encourages simple, clean HTML5 markup and uses SCSS for powerful, easily managed stylesheets. SFUMATO provides coding freedom through tools not mandates.
Our grid uses flexbox.
A new flexbox grid system is part of the SFUMATO layout framework, allowing developers to easily structure scalable page layouts as they would with traditional responsive grid systems.
Why use flexbox? Flexbox makes using viewport units more reliable, uses simpler CSS markup, and doesn't rely on floats and other properties that can make styling a layout more problematic.
You can create grids with simple HTML5 markup, using WAI-ARIA landmark roles for both accessibility, and context-based selectors.
<article role="grid"> <div role="gridcell"> <section> <p>Ricky Baker</p> </section> </div> ...
V1 is broadly compatible.
SFUMATO supports a large number of popular browsers. So even if you support large enterprise customers, it's likely that SFUMATO will work in their environment.
According to statcounter, as of April 2018, SFUMATO works with over 90.33% of web browsers globally.
- Internet Explorer 11 (2013)
- Microsoft Edge 12 (2015)
- Firefox 28 (2014)
- Safari 9 (2015)
- Opera 17 (2013)
- Google Chrome 29 (2013)
- iOS Safari 9.2 (2015)
- Opera Mobile 37 (2016)
- Android Browser 4.4 (2014)
- Chrome for Android 49 (2016)
- Firefox 54 for Android (2017)
V2 has advanced features.
If you don't need to support older web browsers like Internet Explorer 11, SFUMATO 2 leverages modern CSS features like custom properties, which allow you to create advanced user interfaces with features like real-time theming. Do you really need to support old browsers? According to W3Counter old browsers are barely being used.
Nonetheless, browser support for version 2 is quite broad as shown below.
- Edge 15 (April 2017)
- Chrome 49 (March 2016)
- Firefox 31 (March 2014)
- Opera 36 (March 2016)
- Safari 9 (September 2015)
- iOS Safari 9.2 (December 2015)
- Opera Mobile 37 for Android (March 2016)
- Android webview 50 (May 2016)
- Chrome 49 for Android (November 2015)
- Firefox 31 for Android (September 2014)
I'm sure the benefits of scaling web pages is clear. But why use these specific technologies?
Viewport and rem units
The most viable technique for scaling web pages is with CSS, mostly because of its low-overhead, broad support, and hardware acceleration. Of the options available within CSS, viewport units provide the best coverage of these benefits. Viewport units are used for the base fonts and rem units are used for everything else. Scaling based on rem units means your styles are often the same for various screen sizes, which means your SCSS code is smaller and easier to write.
CSS3 transforms like
As with scaling, the benefits of using flexbox for our grid system centers around compatibility and functionality. In an ideal world we'd use CSS grid. But it's not well-supported at the time of this writing.
Flexbox, on the other hand, is widely supported. And although it's not the perfect fit for a grid layout system, it does provide the necessary functionality to make it a great choice. It also provides features a standard float-based grid doesn't, like equal column heights, row or column based layouts, and more.
Why not use a standard float-based grid? Float-based grids are a bit wonky, especially on sites with viewport-based measurements. And floats can create other styling dependencies. Flexbox just works.
Are there any issues?
Not really. The only issue at this time remains with Apple Safari in macOS 10.14 Mojave and below. In those versions Safari does not scale
font-size smoothly. It rounds font sizes down every half pixel, so as the font is scaled, some intermediate sizes jump to the next whole pixel size. This generally affects small text much more than large. And it can make paragraphs wrap differently on occasion. But generally speaking, it's a minor annoyance, and rarely gets in the way.
