How to render svg markup in a HTML page.

You can render SVG markup via:

object,
embed,
iframe,
img,
CSS background-image
and svg inclusion.

HTML elements

Svg

A SVG element represents the root of a Scalable Vector Graphics (SVG) fragment.

A svg tag supports the HTML - Sizing (Width and Height attribute)|html width and height attribute]]. This attribute may be overwritten with CSS width and height property

Example:

The Css

svg {
    width: 200px;
    height:100px
}

The HTML

<svg width="50" height="50" viewBox="0 0 150 150" preserveAspectRatio="none">
        <circle cx="60" cy="60" r="50" fill="#D5D8CB" stroke="#ECDCC6" stroke-width="5"/>
</svg>

Output:

Rendered by WebCode

In a svg tag, Javascript is executed. You can disallow this execution via:

a Content Security Policy. Example:

content-security-policy: sandbox; default-src 'none'; script-src 'none'; plugin-types application/pdf; style-src 'unsafe-inline'; media-src 'self'; object-src 'self';

or by using the image element

Img

SVGs can be included the same way as any bitmap image in a img tag. In a img tag, Javascript is not executed.

<img src="/_media/logo.svg" alt="An example icon" style="width:48px;height:48px" />

Object

Embedded in a document with object.

Example:

<object type="image/svg+xml" data="/_media/logo.svg" width="48px"></object>

Rendered by WebCode

For security reason, the svg is in a top level content, meaning that:

you can't access the page from svg script
the style from the parent don't apply to the object

Video

You can embedded an SVG animation is embedded in a video element

Example:

<video src="/_media/logo.svg" type="image/svg+xml"></video>

Rendered by WebCode

For security reason, the svg is in a top level content, meaning that:

you can't access the page from svg script
the style from the parent don't apply to the object

Security

Note that if an SVG is embedded in a object or video element, the user agent (browser) would not give it access to the DOM of the outer page.

Therefore:

From the perspective of scripts in the SVG resource, the SVG file would appear to have no parent (ie to be in a lone top-level browsing context)
This is not possible to style it from the parent document. Therefore the color should be set up in the SVG
