Django CMS plugin implementing html5 responsive images

Project description


This package provides a plugin for Django CMS 3 similar to
cmsplugin\_filer\_image, but in addition can deliver multiple sizes as a html5
srcset attribute for the img tag.


How the srcset is built is determined by the style choices attribute.

'fullwidth': {
'name': _('full width'),
'srcset': ((960, 0), (640, 0), ),
'sizes': '(max-width: 800px) 640px',
'default_size': (960, 0)

`srcset` ist a tuple of (width, height) tuples which will be used to create
the `srcset` img attribute and also to render the thumbnails with
`sizes` is the value of the `sizes` img attribute, refer to your favorite html5
documentation for information on how to use it. You can also omit it if
`default_size` will be used for the `src` attribute and the corresponding thumbnail as a fallback for browsers which
don't support `srcset`.

By default, the srcset includes high-resolution (2x) images if the source image is large enough. You can disable
this behaviour by setting `DJANGOCMS_RESPONSIVE_IMAGE_ADD_2X = False`. If you are using custom templates older than
v0.1.1, you might update them to support 2x (see `templates/djangocms_responsive_image/default.html` for an example).

0.1.1 added support for high-res images; bugfix
0.1.0 added description field and alt getter with fallback to the default\_alt\_text of the image
0.0.11 added fallback src attribute to default template
