===============
Theming support
===============
.. sectionauthor:: Julius Härtl <jus@bitgrid.net>
The Nextcloud theming app offers some tools for app developers to ensure that apps also match the themed look.
CSS classes
===========
* **.nc-theming-main-background** Background in theming color
* **.nc-theming-main-text** Text in theming color
* **.nc-theming-contrast** Text in white/black color to be shown in front of the theming color
JavaScript
==========
When the theming app is enabled, it provides the **OCA.Theming** object. It can
be used to handle themed instances differently.
.. code-block:: javascript
if(OCA.Theming) {
$('.myapp-element').animate({backgroundColor:OCA.Theming.color});
}
The following information is available:
* **OCA.Theming.color** Main color
* **OCA.Theming.inverted** Will be true on bright theming colors to get contrast with text
* **OCA.Theming.name** Instance name
* **OCA.Theming.slogan** Instance slogan
* **OCA.Theming.url** Instance web address
Icons
=====
The theming app will automatically generate favicons and home screen icons for
each app by using the icon `img/app.svg` inside of the app folder. Any custom
favicon set by an app will only be visible when the theming app is disabled.
