Themes allow you to easily make your Quill editor look good with minimal effort.
To use a custom theme, simply add its stylesheet in the <head>:
<link rel="stylesheet" href="//cdn.quilljs.com/0.20.1/quill.snow.css" />
and specify its usage at initialization:
var editor = new Quill('#editor', {
theme: 'snow'
});
There is currently only one predefined theme snow for Quill.
In the future we will provide more options and even allow you to create your own. We will provide documentation and guidance here once they are finalized.
