Inline SVG Tag Redocly Custom Tag

The inline SVG tag is used to render and style an SVG image in your document.

Syntax and usage

The inline-svg tag requires a file attribute, which provides a file path to an SVG file.

The following example embeds a Redocly logo from an svg file:

{% inline-svg file="../../images/redocly-logo.svg" /%}

Before the SVG renders on the document, it's optimized using SVGO. The id attribute is also prefixed with the relative file path to avoid conflicts.

Styling the SVG

SVGs can be styled using CSS rules added to your project, but you need a way to reference the SVG. There's two ways to add an identifier to the SVG:

1. Modify the HTML in the SVG file and add a class.

2. Apply a CSS class directly to the inline-svg tag, as in the following example:

   {% inline-svg file="../../images/redocly-logo.svg" .some-custom-class /%}

The second approach provides more flexibility to writers using the Markdoc tag.

Attributes

Examples

Render SVG from file

The following example adds an inline SVG to your document:

{% inline-svg file="../../images/ramen-icon.svg" /%}

Apply styling to SVG

This example adds custom styling to change the size and color. The following CSS has been added to the @theme/styles.css file:

.example-svg-styles {
    svg {
        width: 80px;
        height: auto;
    }

    path {
        fill: blue;
    }
}

The example below adds that class to the inline SVG:

{% inline-svg file="../../images/ramen-icon.svg" .example-svg-styles /%}

Best practices

You can improve page performance by using a single SVG file and applying styling changes using CSS. That way you don't have to load separate files.
