Vue Box Model Editor

Box Model Editor is a Vue component that allows the editing of the box model of a DOM element. This is totally inspired to the Chrome Dev Tools component.

[!IMPORTANT]

FEATURE DISCLAIMER

This component does NOT actually manipulate the DOM in any way: its purpose it to receive input models describing the actual box model of an element, allowing the editing of this model and returning the manipulated model as output.

The typical intended use case for this component is inside an editor (or similar kind of product).

Installation

You can install the package in your project with the following command:

npm install @pierodetomi/v-box-model-editor

Usage

This library exports the BoxModelEditor component. You can use it as follows:

// INSIDE YOUR CODE
import { BoxModel, SizeModel, BorderModel, BoxModelEditorOptions, BoxModelEditor } from '@pierodetomi/v-box-model-editor'; // Import component
import '@pierodetomi/v-box-model-editor/style.css'; // Import component's style

[...]

margin = new BoxModel();
border = new BorderModel();
padding = new BoxModel();
size = new SizeModel();
options = new BoxModelEditorOptions();
options.availableUnits = [ /* you can override the default available units */ ]
options.style.[style_property] = ... // Replace [style_property] with one of the available options: see below

<!-- INSIDE YOUR TEMPLATE -->
<BoxModelEditor :options="options"
                :margin="margin"
                :border="border"
                :padding="padding"
                :size="size"
                @update:margin="value => margin = value"
                @update:border="value => border = value"
                @update:padding="value => padding = value"
                @update:size="value => size = value" />

The options property expects an instance of the BoxEditorModelOptions class. This class exposes the following options:

| Option | Type | Default Value | Description | | --- | --- | --- | --- | | availableUnits | string[] | ['px', 'em', 'rem', 'vw', 'vh', '%'] | The units that are available when the user opens the units dropdown | | style | BoxModelEditorStyleOptions | new BoxModelEditorStyleOptions() | The style options that can be used to personalize the appearance of the component |

The BoxModelEditorStyleOptions class exposes the following options:

| Option | Type | Default Value | Description | | --- | --- | --- | --- | | bordersColor | string | '#000' | The color of the borders of the visual containers | | marginBackgroundColor | string | '#f9cc9d' | The background color of the margin model container | | borderBackgroundColor | string | '#ffeebc' | The background color of the border model container | | paddingBackgroundColor | string | '#c4dfb8' | The background color of the padding model container | | sizeBackgroundColor | string | '#a0c6e8' | The background color of the size model container | | textColor | string | '#252525' | The color of the text (labels & numbers) | | inputFontSize | number | 11 | The font size of the inputs & values displayed | | unitDropdownBackgroundColor | string | '#f9f9f9' | The background color of the units dropdown | | unitDropdownTextColor | string | '#252525' | The text color of the units dropdown | | unitDropdownHoverBackgroundColor | string | '#d1d1d1' | The background color of an item of the units dropdown, when hovered | | unitDropdownHoverTextColor | string | '#252525' | The text color of an item of the units dropdown, when hovered | | unitDropdownFontSize | number | 12 | The font size of the text inside the units dropdown |

box, border and size models

The margin and padding properties use the same input/output model, the BoxModel, with the following structure:

class BoxModel {
  public isLinked: boolean = true;

  public top: number = null;

  public topUnit: string = 'px';
  
  public right: number = null;
  
  public rightUnit: string = 'px';

  public bottom: number = null;
  
  public bottomUnit: string = 'px';

  public left: number = null;

  public leftUnit: string = 'px';
}

The border property uses the BorderModel input/output model, that's an extension of the BoxModel model that adds only the style property (with default value 'solid'):

class BorderModel extends BoxModel {
  public style: string = 'solid';
}

The size property uses the SizeModel input/output model, with the following structure:

class SizeModel {
  public width: number = null;
  
  public widthUnit: string = 'px';
  
  public height: number = null;

  public heightUnit: string = 'px';
}
