SVGs are ideal for image fallbacks due to their scalability and compatibility. To implement this, first, embed the SVG directly into HTML using an ‘img’ tag or CSS background-image property. This allows modern browsers to render the SVG. For older browsers that don’t support SVG, use a PNG or JPEG as a fallback within the same ‘img’ tag or CSS rule.
In the ‘img’ tag method, include the SVG in the ‘src’ attribute and the fallback image in the ‘onerror’ attribute like so: <img src="image.svg" onerror="this.src='image.png';">.
For CSS, specify the SVG as the primary background-image and the fallback image as the secondary one: background-image: url('image.svg'), url('image.png');. The browser will attempt to load images from left to right, falling back to the next if it fails.
