Weekly Platform News: Preventing Image Loads with the Picture Element, the Web We Want, Svg Styles Are Not Scoped
This week's browser news roundup covers conditional image loading with the <picture></picture>
element, a platform for web developer feedback, and a heads-up about inline SVG styling. Let's dive into the key updates:
Conditional Image Loading with <picture></picture>

element offers a clever way to prevent unnecessary image downloads based on media queries. For instance, you can load a high-resolution image only when the viewport is sufficiently wide. A simple example (as demonstrated by Scott Jehl):
<img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/174494143370978.png" class="lazy" alt="Weekly Platform News: Preventing Image Loads with the Picture Element, the Web We Want, Svg Styles Are Not Scoped ">
