Portugal Dinosaur Discovery: New Herbivorous Species
Here’s a breakdown of the HTML snippet, focusing on the image and its surrounding context:
Overall Structure:
the code represents a section of a news article or blog post, likely from the Dutch broadcaster NOS (indicated by the cdn.nos.nl domain). It contains an image, a caption, and accompanying text. The sc- classes are likely generated by a CSS-in-JS library (like Styled Components) and are used for styling.
Key Elements:
* <figure>: This element encapsulates the image and its caption, semantically representing a self-contained piece of content.
* <picture>: This is a modern HTML element designed for responsive images. it allows you to provide multiple image sources wiht different resolutions and formats, and the browser will choose the most appropriate one based on the user’s screen size, resolution, and browser support.
* srcset attribute: This is the core of the <picture> element. It lists the available image sources along with their widths (e.g., https://cdn.nos.nl/image/2025/09/15/1271265/128x72a.jpg 128w). The w unit indicates the width of the image in pixels.
* sizes attribute: This attribute tells the browser how the image will be displayed at different viewport sizes. In this case:
* (-width: 786px) 786px: If the viewport width is less than 786px, the image will occupy 786px of space.
* 100vw: otherwise (viewport width is 786px or greater), the image will occupy 100% of the viewport width.
* <img>: This is the actual image element.
* src: The default image source to use if the browser doesn’t support <picture> or if none of the srcset images match. Here, it’s set to https://cdn.nos.nl/image/2025/09/15/1271265/1024x576a.jpg.
* alt: An empty string, which is not ideal for accessibility. It shoudl contain a descriptive text choice for the image.
* decoding="async": Tells the browser to decode the image asynchronously, improving page load performance.
* loading="lazy": Enables lazy loading, meaning the image will only be loaded when it’s near the viewport.
* class: CSS classes for styling.
* <figcaption>: Provides a caption for the image: “The skull is in good condition”.
* <div> with class sc-2c7195-1 dhuKSd: These divs contain the paragraphs of text accompanying the image.
* <p> with class sc-2ea02837-0 fedhGB: These are the paragraphs themselves, containing the article text.They have unique id attributes for potential referencing.
* Button with SVG: A button containing a fullscreen icon, likely to allow the image to be viewed in a larger format.
* **Span with class `sc-568a4295-0 sc-9f391fae-3 ihkAIz
