Extra CSS class (or classes) that will be set internally on the <body>
element of the <iframe>
enclosing the minimap.
By default, the minimap feature will attempt to clone all website styles and re-apply them in the <iframe>
for the best accuracy.
However, this may not work if the content of your editor inherits the styles from parent containers, resulting in inconsistent
look and imprecise scrolling of the minimap.
This optional configuration can address these issues by ensuring the same CSS rules apply to the content of the minimap
and the original content of the editor.
For instance, consider the following DOM structure:
<div class="website">
<!-- ... -->
<div class="styled-container">
<!-- ... -->
<div id="editor">
<!-- content of the editor -->
</div>
</div>
<!-- ... -->
</div>
and the following CSS styles:
.website p {
font-size: 13px;
}
.styled-container p {
color: #ccc;
}
To maintain the consistency of styling (font-size
and color
of paragraphs), you will need to pass the CSS class names
of these containers:
ClassicEditor
.create( document.getElementById( 'editor' ), {
minimap: {
extraClasses: 'website styled-container'
}
} )
.then( ... )
.catch( ... );
