TLDR

To effortlessly scale an embedded SVG, ensure the width and height attributes on the <object> tag are set to "100%", and confirm the SVG's viewBox attribute is correctly defined for fluid scaling:

<object data="image.svg" type="image/svg+xml" width="100%" height="100%"></object>

Within your SVG file:

<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg"> <!-- The magical land of shapes and paths --> </svg>

This strategy enables the SVG to maintain its aspect ratio as it flexibly fills its parent container.

Grab some coffee, here's the SVG scaling low-down

Scaling is ingrained in an SVG's DNA - optimized for any dimension without losing quality. Coupled with the <object> tag, you hit a jackpot: it keeps its responsive and crisp nature. Here are some keystone attributes: preserveAspectRatio, viewBox, and the blend of HTML and CSS directives.

The aspect ratio whisperer: preserveAspectRatio

Our SVG doesn't want to warp or crop. It wants to scale while staying in shape, just like your favorite fitness guru. preserveAspectRatio="xMinYMin meet" ensures it scales gracefully to fit the smallest dimension.

Your map to scaling: viewBox

The viewBox attribute is your SVG's best friend for responsive scaling. A value like viewBox="0 0 200 200" instructs the SVG's coordinate system, assuring it resizes just the way you want.

<object> tag and CSS: Twists and scales

Entail your <object> within a <div> and watch CSS control size like a maestro:

<div style="width: 50%; height: 50%;"> <object type="image/svg+xml" data="image.svg" style="width: 100%; height: auto;"></object> <!-- Ladies and gentlemen, we got 'em! --> </div>

Navigating successfully between the technicalities of SVG presentation and HTML structure, we get CSS, the stylist of scalability.

Battling stubborn SVGs: Advanced techniques

Master the SVG with JavaScript

Dynamically manipulate the SVG's domestic attributes with the power of JavaScript:

const objectElem = document.querySelector('object'); const svgDoc = objectElem.contentDocument; const svgElem = svgDoc.querySelector('svg'); svgElem.setAttribute('viewBox', '0 0 newWidth newHeight'); // Voila! Now we are talking! Real-time responsiveness

Plan B for browser issues

Browsers aren't always on your side. Tools like Inkscape's SVG browser resizing blueprint can help dodge these roadblocks, ensuring broader cross-browser compatibility.

Beyond <object>: A world of alternatives

<object> is your reliable pal, but alternatives like <img> tag with CSS-controlled <div> containers can offer more predictable scaling outcomes.
