Obsidian Canvas Snippets

Here is a list of useful snippets to improve Obsidian Canvas.
I will add more as I create them.
Don't forget to share & star πŸ™‚

(The snippets are created for Prism Theme and you probably need to tweak them)

Contents:

Node Icons

✍🏽 Usage

First add the snippets, then place one or more spans in your node, including the ni class (short for "node icon"), icon position, and the icon itself.

  • Positions:
    • Horizontal: l (left), c (center), r (right)
    • Vertical: t (top), m (middle), b (bottom)
  • Icon Types:
    • Emoji: <span data-icon="🎈"></span>
    • Text: <span>Custom Text</span>
    • Custom Icon (using Iconize Plugin): <span>:LiFolderTree:</span>

Here are three examples:

Your markdown here

/* emoji as icon, top left */
<span data-icon="☒" class="ni t l" />

/* text as icon, bottom left */
<span class="ni b l">Custom Text</span>

/* text as icon, middle right */
<span class="ni m r">:LiFolderTree:</span>

Your markdown here

Note

Middle m and center c positions don't work correctly with custom shapes, because of overflow.

πŸ“ƒ Snippet

Add this css snippet. Feel free to change padding, margin and others based on your theme styles.

.canvas-node:not(.is-editing) {
  transform: rotate(0deg);

  .ni {
    padding: 4px;
    position: absolute;
    color: hsl(var(--canvas-color));
    height: max-content;

    &[data-icon] {
      padding: 0;
      font-family: "Segoe UI Emoji";
      font-size: 1rem;

      &:before {
        content: attr(data-icon);
      }
    }

    &.t {
      top: 0;
    }

    &.m {
      top: calc(50% - 12px);
    }

    &.b {
      bottom: 0;
    }

    &.r {
      right: -12px;
    }

    &.c {
      left: calc(50% - 4px);
    }

    &.l {
      left: 0;
    }
  }
}

Node Shapes

✍🏽 Usage

After adding the snippets, you can add any element (like a <span>) including the class name of the shape. For example, to create a circular node with centered content, put this in your node:

Your node content...

<span class="shape-circle node-center"></span>

πŸ“ƒ Snippets

General

For centered-content style:

.canvas-node:has(.shape-rhombus, .shape-hexagon, .shape-circle) {
  .markdown-rendered {
    &::before {
      display: none !important;
    }

    &::after {
      display: none !important;
    }
  }
}

.canvas-node:has(.node-center) {
  .markdown-rendered .markdown-preview-section {
    display: flex;
    align-items: center;
    justify-content: center;
    flex-direction: column;
    height: 100%;

    > div * {
      text-align: center !important;
      text-align-last: center !important;
    }
  }
}

Circle

.canvas-node:has(.shape-circle) {
  &.is-focused {
    background-color: rgba(0, 0, 0, 0.5);
  }

  .canvas-node-container {
    border-radius: 50%;
    aspect-ratio: 1 / 1;
    height: 100%;
    width: auto;

    .markdown-embed-content {
      padding: 15%;
    }

    .markdown-rendered {
      padding: 0 !important;

      &::before {
        display: none;
      }

      &::after {
        display: none;
      }
    }
  }
}

Rhombus

.canvas-node:has(.shape-rhombus) {
  border: solid 4px hsl(var(--canvas-color)) !important;
  background: hsl(var(--canvas-color)) !important;
  clip-path: polygon(50% 0, 100% 50%, 50% 100%, 0 50%);

  .canvas-node-container {
    clip-path: inherit;
    border: none !important;

    .markdown-embed-content {
      padding: calc(var(--canvas-node-height) / 4)
        calc(var(--canvas-node-width) / 4);
    }

    .markdown-rendered {
      padding: 8px !important;
    }
  }
}

Hexagon

.canvas-node:has(.shape-hexagon) {
  border: solid 2px hsl(var(--canvas-color)) !important;
  background: hsl(var(--canvas-color)) !important;
  clip-path: polygon(25% 0%, 75% 0%, 100% 50%, 75% 100%, 25% 100%, 0% 50%);
  /* for regular hexagon */
  aspect-ratio: 8 / 7;
  width: auto !important;

  .canvas-node-container {
    clip-path: inherit;
    border: none !important;
  }

  .markdown-embed-content {
    padding: 16% 16%;
  }

  .markdown-rendered {
    padding: 8px !important;
  }
}

πŸ’Ž Creating Shapes

In oreder to create your custom shape, you can use this template:

.canvas-node:has(.shape-your-shape-name) {
  border: solid 2px hsl(var(--canvas-color)) !important;
  background: hsl(var(--canvas-color)) !important;

  clip-path: /* shape path */

  .canvas-node-container {
    clip-path: inherit;
    border: none !important;
  }

  .markdown-embed-content {
    padding: /* padding 1 */
  }

  .markdown-rendered {
    padding: /* padding 2 */
  }
}

Replace clip-path value with your desired shape path, and change the paddings to make the inner content look readable. Clippy is a great tool for working with css paths.

Here's a simple example, using Obsidian logo as a custom shape!
