theme.json

主题的 theme.json 文件是定制编辑器体验的最佳方式之一,很可能是在使用更复杂解决方案之前最先用到的工具。

提供默认控件/选项

由于 theme.json 作为配置工具,可通过多种方式精细定义可用选项。本节将以双色调为例进行说明,该功能横跨多个区块并支持不同层级的访问权限。

为所有图片相关区块启用核心双色调选项和自定义功能:

{
	"version": 3,
	"settings": {
		"color": {
			"customDuotone": true,
			"duotone": [
			]
		}
	}
}

为所有图片相关区块提供主题预定义色彩选项、核心选项及自定义功能:

{
	"version": 3,
	"settings": {
		"color": {
			"duotone": [
				{
					"colors": [ "#000000", "#ffffff" ],
					"slug": "foreground-and-background",
					"name": "前景色与背景色"
				},
				{
					"colors": [ "#000000", "#ff0200" ],
					"slug": "foreground-and-secondary",
					"name": "前景色与辅助色"
				},
				{
					"colors": [ "#000000", "#7f5dee" ],
					"slug": "foreground-and-tertiary",
					"name": "前景色与第三色"
				},
			]
		}
	}
}

为文章特色图片区块提供预定义默认选项并开放全部自定义功能:

{
	"version": 3,
	"settings": {
		"color": {
			"custom": true,
			"customDuotone": true
		},
		"blocks": {
			"core/post-featured-image": {
				"color": {
					"duotone": [
						{
							"colors": [ "#282828", "#ff5837" ],
							"slug": "black-and-orange",
							"name": "黑橙配色"
						},
						{
							"colors": [ "#282828", "#0288d1" ],
							"slug": "black-and-blue", 
							"name": "黑蓝配色"
						}
					],
					"customDuotone": true,
					"custom": true
				}
			}
		}
	}
}

为文章特色图片区块仅提供预定义默认选项和核心选项(禁用自定义功能):

{
	"version": 3,
	"settings": {
		"color": {
			"custom": true,
			"customDuotone": true
		},	
		"blocks": {
			"core/post-featured-image": {
				"color": {
					"duotone": [
						{
							"colors": [ "#282828", "#ff5837" ],
							"slug": "black-and-orange",
							"name": "黑橙配色"
						},
						{
							"colors": [ "#282828", "#0288d1" ],
							"slug": "black-and-blue",
							"name": "黑蓝配色"
						}
					],
					"customDuotone": false,
					"custom": false
				}
			}
		} 
	}
}

使用 theme.json 限制界面选项

按区块限制选项

除了定义默认值,使用 theme.json 还可以完全移除某些选项,转而依赖主题预设配置。下图直观展示了同一段落区块的两种极端设置:

受限界面示意图

延续双色调的示例,这意味着您可以对图片区块开放全部双色调功能,而仅限制文章特色图片区块的权限:

{
	"version": 3,
	"settings": {
		"color": {
			"custom": true,
			"customDuotone": true
		},
		"blocks": {
			"core/image": {
				"color": {
					"duotone": [],
					"customDuotone": true,
					"custom": true
				}
			},
			"core/post-featured-image": {
				"color": {
					"duotone": [],
					"customDuotone": false,
					"custom": false
				}
			}
		}
	}
}

您可阅读此文档深入了解如何通过 theme.json 启用/禁用选项。

禁用继承默认布局

如需对群组区块等容器区块禁用“继承默认布局”设置,请移除以下配置段:

"layout": {
	"contentSize": null,
	"wideSize": null
},

全局限制选项

在区块主题或经典主题中使用 theme.json 时,以下设置将全局禁用默认颜色与排版控件,大幅限制可用功能:

{
	"version": 3,
	"settings": {
		"layout": {
			"contentSize": "750px"
		},
		"color": {
			"background": false,
			"custom": false,
			"customDuotone": false,
			"customGradient": false,
			"defaultGradients": false,
			"defaultPalette": false,
			"text": false
		},
		"typography": {
			"customFontSize": false,
			"dropCap": false,
			"fontStyle": false,
			"fontWeight": false,
			"letterSpacing": false,
			"lineHeight": false,
			"textDecoration": false,
			"textTransform": false
		}
	}
}

若需启用上述某项功能,只需将对应值改为 true 即可实现更精细的控制。
