如何设置 CKEditor 5(经典编辑器)的高度

Answering my own question as it might help others.

CKEditor 5 no longer comes with a configuration setting to change its height. The height can be easily controlled with CSS.

There is one tricky thing though, if you use the Classic Editor:

<div id="editor1"></div>

ClassicEditor
.create( document.querySelector( '#editor1' ) )
.then( editor => {
// console.log( editor );
} )
.catch( error => {
console.error( error );
} );

Then the Classic Editor will hide the original element (with id editor1) and render next to it. That's why changing height of #editor1 via CSS will not work.

The simplified HTML structure, after CKEditor 5 (the Classic Editor) renders, looks as follows:

<!-- This one gets hidden -->
<div id="editor1" style="display:none"></div>
<div class="ck-reset ck-editor..." ...>
<div ...>
<!-- This is the editable element -->
<div class="ck-blurred ck-editor__editable ck-rounded-corners ck-editor__editable_inline" role="textbox" aria-label="Rich Text Editor, main" contenteditable="true">
...
</div>
</div>
</div>

In reality the HTML is much more complex, because the whole CKEditor UI is rendered. However the most important element is the "editing area" (or "editing box") marked with a ck-editor__editable_inline class:

<div class="... ck-editor__editable ck-editor__editable_inline ..."> ... </div>

The "editing area" is the white rectangle where one can enter the text. So to style / change the height of the editing area, it is enough to target the editable element with CSS:

<style>
.ck-editor__editable_inline {
min-height: 400px;
}
</style>

As for configuring the width of the CKEditor 5:

CKEditor 5 no longer comes with a configuration setting to change its width but its width can be easily controlled with CSS.

To set width of the editor (including toolbar and editing area) it is enough to set width of the main container of the editor (with .ck-editor class):

<style>
.ck.ck-editor {
max-width: 500px;
}
</style>

editor.ui.view.editable.editableElement.style.height = '300px';

Add this to your stylesheet:

.ck-editor__editable {
min-height: 200px !important;
}

Setting the height via a global stylesheet. Just add to your common .css file (like style.css):

.ck-editor__editable {
min-height: 500px;
}

If you wish to do this programatically, the best way to do it is to use a Plugin. You can easily do it as follows. The following works with CKEditor 5 version 12.x

function MinHeightPlugin(editor) {
this.editor = editor;
}


MinHeightPlugin.prototype.init = function() {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: '300px'
}
}
});
};


ClassicEditor.builtinPlugins.push(MinHeightPlugin);
ClassicEditor
.create( document.querySelector( '#editor1' ) )
.then( editor => {
// console.log( editor );
})
.catch( error => {
console.error( error );
});

Or if you wish to add this to a custom build, you can use the following plugin.

class MinHeightPlugin extends Plugin {
init() {
const minHeight = this.editor.config.get('minHeight');
if (minHeight) {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: minHeight
}
}
});
}
}
}

This adds a new configuration to the CKEditor called "minHeight" that will set the editor minimum height which can be used like this.

ClassicEditor
.create(document.querySelector( '#editor1' ), {
minHeight: '300px'
})
.then( editor => {
// console.log( editor );
} )
.catch( error => {
console.error( error );
} );

Just add it to the style tag.

<style>
.ck-editor__editable
{
min-height: 150px !important;
max-height: 400px !important;
}
</style>

Just test it's work. Hoping help you

var editor_ = CKEDITOR.replace('content', {height: 250});

If you use jQuery and the CKEditor 5 has to be applied to a textarea, there is a "quick and dirty" solution.

The condition:

<textarea name='my-area' id='my_textarea_id'>

If you use jQuery the Editor call could be:

var $ref=$('#my_textarea_id');


ClassicEditor
.create( $ref[0] ,{
// your options
} )
.then( editor => {
// Set custom height via jQuery by appending a scoped style
$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: 200px !important;}</style>').insertAfter($ref);


} )
.catch( error => {
console.error( error );
} );

In other words, after rendering, you can address the same element used to build the editor and append after a scoped style tag with containing the custom height.

$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: 200px !important;}</style>').insertAfter($ref);

If you like to use a function (or some class method) to do this, you need something like this:

var editorBuildTo = function(id,options){
var options=options || {};
//Height represents the full widget height including toolbar
var h = options.height || 250; //Default height if not set
var $ref = $('#'+id);
  

h=(h>40?h-40:h);//Fix the editor height if the toolbar is simple


ClassicEditor
.create( $ref[0] ,{
// your options
} )
.then( editor => {
// Set custom height via jQuery
$('<style type="text/css" scoped>.ck-editor .ck-editor__editable_inline {min-height: '+h+'px !important;}</style>').insertAfter($ref);
} )
.catch( error => {
console.error( error );
} );
}


editorBuildTo('my_textarea_id',{
height:175,
// other options as you need
});

This works well for me

I tried to set the height and width on the config but it just didn't work on the classic Editor. I was able to change the height of the editor programmatically on Vue by doing this.

mounted() {
const root = document.querySelector('#customer_notes');


ClassicEditor.create(root, config).then(editor=>{
// After mounting the application change the height
editor.editing.view.change(writer=>{
writer.setStyle('height', '400px', editor.editing.view.document.getRoot());
});
});
}

In the case of ReactJS.

<CKEditor
editor={ClassicEditor}
data="<p>Hello from CKEditor 5!</p>"
onInit={(editor) => {
// You can store the "editor" and use when it is needed.
// console.log("Editor is ready to use!", editor);
editor.editing.view.change((writer) => {
writer.setStyle(
"height",
"200px",
editor.editing.view.document.getRoot()
);
});
}}
/>

Use max-height and min-height both. Beacuse max-height give scroll bar option after reached maximum mention height. Where min-height give static height to <textarea>.

.ck-editor__editable { max-height: 400px; min-height:400px;}

Building on @Jaskaran Singh React solution. I also needed to ensure it was 100% height to it's parent. I achieved this by assigning a ref called "modalComponent" and further adding this code:

editor.editing.view.change(writer => {


let reactRefComponentHeight = this.modalComponent.current.offsetHeight
let editorToolbarHeight = editor.ui.view.toolbar.element.offsetHeight
let gapForgiveness = 5
let maximizingHeight = reactRefComponentHeight - editorToolbarHeight - gapForgiveness


writer.setStyle(
'height',
`${maximizingHeight}px`,
editor.editing.view.document.getRoot()
)
})

From CKEditor 5 version 22 the proposed programmatic solutions are not working. Here it is how I get the work done:

ClassicEditor.create( document.querySelector( '#editor' ) )
.then( editor => {
editor.ui.view.editable.element.style.height = '500px';
} )
.catch( error => {
console.error( error );
} );

.ck-editor__editable {min-height: 500px;}

<div>
<textarea id="editor">Hi world!</textarea>
</div>
<script src="https://cdn.ckeditor.com/ckeditor5/22.0.0/classic/ckeditor.js"></script>

This CSS Method works for me:

.ck-editor__editable {
min-height: 400px;
}

Simply you can add this to your CSS file

.ck-editor__editable {min-height: 150px;}

Put this CSS in your global CSS file and the magic will happen. CkEditor is full of unsolved mysteries.

.ck-editor__editable_inline {
min-height: 400px;
}

I resolve this just adding in my layout page

<style>
.ck-content{
height: 250px;
}
</style>

Hope i help someone :D

Use css:

.ck.ck-editor__main .ck-content {
height: 239px;
}

Add this to your global stylesheet, this will increase the size of the CKEditor :)

.ck-editor__editable_inline {
min-height: 500px;
}

For this particular version https://cdn.ckeditor.com/4.16.0/standard/ckeditor.js, the below code block worked for me. .cke_contents { height: 500px !important; } I guess the difference is just the fact that is it in plural.

In my case it worked for me Add a ck class and write style like below:

<style>
.ck {
height: 200px;
}


</style>

If its in latest version of Angular say 12 or 12+. We can add below style to your components style file.

:host ::ng-deep .ck-editor__editable_inline { min-height: 300px; }

Using plugin here I came up with this

let rows: number;
export class MinHeightPlugin {
constructor(public editor) {
}
init = function () {
this.editor.ui.view.editable.extendTemplate({
attributes: {
style: {
minHeight: (rows * 40) + 'px',
}
}
});
};
}
export const MinHeightPluginFactory = (rowss: number): typeof MinHeightPlugin => {
rows = rowss;
return MinHeightPlugin;
};

and the usage(4 rows each rows is considered 40px height):

 this.editor.builtinPlugins.push(MinHeightPluginFactory(4));

I couldn't manage to make rows variable local to MinHeightPlugin, does anyone know how to do it?

.ck-editor__editable_inline {
min-height: 400px;
}

This makes height change for every editor used across all components. So it doesn't work in my case.

In Case of react js
<CKEditor
toolbar = {
[
'heading',
'bold',
'Image'
]
}
editor={ClassicEditor}
data={this.state.description}//your state where you save data
config=\{\{ placeholder: "Enter description.." }}
onChange={(event, editor) => {
const data = editor.getData();
this.setState({
description : data
})
}}
onReady={(editor)=>{
editor.editing.view.change((writer) => {
writer.setStyle(
//use max-height(for scroll) or min-height(static)
"min-height",
"180px",
editor.editing.view.document.getRoot()
);
});
}}
/>
