Gumby Responsive Images
This module will preload and insert images based on media queries and/or feature detection. For more detailed documentation please check out the Gumby docs.
A bower package is available to install this module into your project. We recommend using this method to install Gumby and any extra UI modules, however you can alternatively move the individuals files into your project.
$ bower install gumby-images
<!-- Include gumby.js followed by UI modules. Or concatenate and minify into a single file--> <script src="/bower_components/gumby/js/libs/gumby.js"></script> <script src="/bower_components/gumby/js/libs/ui/gumby.skiplink.js"></script> <script src="/bower_components/gumby/js/libs/ui/gumby.toggleswitch.js"></script> <script src="/bower_components/gumby-images/gumby.images.js"></script> <script src="/bower_components/gumby/js/libs/gumby.init.js"></script> <!-- In production minifiy and combine the above files into gumby.min.js --> <script src="js/gumby.min.js"></script> <script src="js/plugins.js"></script> <script src="js/main.js"></script>
Using the responsive images module is simple. Add a
gumby-media attribute to any element containing any number of comma separated media query / image path pairs. Media queries and their associated images should be separated with a pipe. You can also add a
gumby-supports attribute to any element, containing any number of comma seaparted features / image path pairs, in the same format as
gumby-media. Features will be tested with Modernizr so ensure your Modernizr build contains all the tests you require. Both
gumby-supports will fallback to the image supplied in
gumby-default. If applied to an
src will be updated otherwise the
background-image will be used.
<img gumby-media="only screen and (max-width: 768px) and (min-width: 501px)|img/img_silence_demo-768.jpg, only screen and (max-width: 500px)|img/img_silence_demo-500.jpg" gumby-default="img/img_silence_demo.jpg" /> <img gumby-supports="webp|img/img_silence_demo.webp" gumby-default="img/img_silence_demo.jpg" />
> can be used as shorthand for
min-width to make it easier and less verbose.
For exampe, the following...
<div gumby-media="< 768px | 2-1-0"></div>
Will be converted to...
<div gumby-media="(max-width: 768px) | 2-1-0"></div>
