* Alt Text: Young people’s educational paths are strongly influenced by their socioeconomic background and gender. The Aspire research project at the Upper Austria University of Applied Sciences has been investigating young people’s educational paths and their success factors for four years.
* Available Sizes: The image is available in multiple sizes: 320w, 480w, 640w, and 960w (both in webp and jpg formats).
Key Observations:
* Responsive Images: The code uses the <picture> element with <source> tags to provide different image sizes based on the screen size. This is a good practice for optimizing web performance.
* WebP Format: The code prioritizes the WebP image format, which generally offers better compression and quality than JPEG. It falls back to JPEG for browsers that don’t support WebP.
* Lazy Loading: The loading="lazy" attribute on the <img> tag indicates that the image will only be loaded when it’s near the viewport, further improving performance.
* Alt Text: Both images have descriptive alt text, which is important for accessibility and SEO.
