3I/ATLAS at Perihelion: Loeb’s Q&A – October 2025
Hear’s a breakdown of the HTML code you provided, focusing on what it represents:
Overall Structure:
This code snippet represents an image embedded within a Medium.com article (or a similar platform using similar HTML structure).It’s designed to be responsive,meaning it will adjust its size based on the screen it’s viewed on.
Key Elements and Attributes:
* <div role="button" tabindex="0" class="nc nd fr ne bi nf">: This is a container that acts like a button. Clicking it is intended to show the image in full size.
* role="button": Indicates this element should behave like a button for accessibility.
* tabindex="0": Makes the element focusable using the Tab key.
* The various class attributes (nc, nd, fr, etc.) are likely CSS classes used for styling and layout within the Medium platform.
* <span class="fw fx fy ao fz ga gb gc gd speechify-ignore">Press enter or click to view image in full size</span>: This is the text displayed within the “button” area. It prompts the user to interact with the image.
* speechify-ignore: This class likely tells a text-to-speech tool to skip reading this text.
* <div class="mt mu ol">: A container for the image itself.
* <picture>: This element is used to provide multiple image sources for different screen sizes and resolutions, improving performance and user experience.
* <source srcset="...">: Thes tags define different versions of the image,optimized for various screen widths (e.g., 640w, 720w, 1400w). The browser will choose the most appropriate version based on the device’s screen size and pixel density. The type="image/webp" indicates that the preferred image format is WebP (a modern image format that offers better compression than JPEG).
* <img alt="" class="bi ma ng c" width="700" height="1060" loading="lazy" role="presentation"/>: This is the actual image tag.
* alt="": The alt attribute is notable for accessibility. It provides option text for the image if it cannot be displayed.In this case, it’s empty, which is not ideal. It should contain a descriptive text.
* width="700" and height="1060": These attributes specify the image’s dimensions.
* loading="lazy": This attribute tells the browser to only load the image when it’s near the viewport (the visible area of the page), improving initial page load time.
* role="presentation": Indicates that the image is purely for visual presentation and doesn’t convey semantic meaning.
* <figcaption class="nh fm ni mt mu nj nk bg b bh ab eb">(Image Credit: chris michel, National Acad</figcaption>: This is the caption for the image. It provides attribution details.
Image Source:
The image is hosted on miro.medium.com and the filename is 1*LE3Xlzc3hNG5VDAGlDP8KQ.jpeg.It appears to be a JPEG image, but the <picture> element attempts to serve a WebP version if the browser supports it.
In Summary:
This code snippet is a well-structured and responsive image element designed for use on a platform like Medium
