Obsidian 样式：Canvas 卡片美化

canvas 是 Obsidian 的白板插件，默认的卡片框看起来比较单调，可以对白板卡片做一定的美化。

卡片文字居中

canvas 卡片文字默认是左居中的，不太美观，可以让卡片文字默认居中。

  text-align: center;
}

白板隐私模式优化

有时候分享白板样式的时候需要隐藏自己信息，这就用到了隐私模式。

但 Obsidian 的隐私模式只对英文有效，英文会自动打码，但中文却打码了个寂寞，经过 css 片段修复，完美解决了这个问题。效果如下：

 /*

 * @Source: Pkmer.cn
*/
/* blur node */
.is-text-garbled .canvas-node  *,
.is-text-garbled .markdown-preview-section div pre code {
  text-shadow: 0 0 6px currentColor !important;
	-webkit-text-fill-color: transparent !important;
}
/* blur media */
.is-text-garbled .canvas-node-container div img,
.is-text-garbled .canvas-node-container div svg,
.is-text-garbled .canvas-node-container div video,
.is-text-garbled .canvas-node-container div webview,
.is-text-garbled .canvas-node-container div iframe {
  filter: blur(4px) !important;
}

多彩卡片框

如图这个效果

.canvas-node {
    background-color: var(--background-primary);
    border-radius: 0px;
    --shadow-border-themed-inset: inset 0 0 0 1px rgb(var(--canvas-color));
    --shadow-border-themed: 0 0 0 2px rgb(var(--canvas-color));
    position: absolute;
    width: 0;
    height: 0;
    box-shadow: 15px 15px 0 -2.5px #fff, 15px 15px 0 0 var(--text-normal);
    border: 2.5px solid var(--text-normal);
  }
  
  .canvas-node.is-themed .canvas-node-content {
    background: var(--background-primary);
  }
  
  .canvas-node.is-themed:before {
    background: rgb(var(--canvas-color));
    content: "";
    position: absolute;
    top: 15px;
    left: 15px;
    width: 100%;
    height: 100%;
    border-radius: 0px;
  }

  .canvas-node-container {
  background: transparent;
  border-radius: 0px;
  border: none;
  contain: strict;
  display: flex;
  height: 100%;
}
  
.canvas-node-content.markdown-embed > .markdown-embed-content > .markdown-preview-view .markdown-preview-pusher + div > *:first-child {
    color: rgb(var(--canvas-color));
}

聚焦卡片特效

聚焦卡片意思是如果点击某个颜色的卡片，周围其他颜色的卡片就会黯淡，重点突出同色卡片。

效果如下：

只要连接线跟卡片设置同一个颜色，即可实现高亮效果。

这个 css 最开始由 @boninall 设计，目前版本是在此基础上稍加修改后的版本。
