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>

The <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/imghwm/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/174494143370978.png?x-oss-process=image/resize,p_40" class="lazy" alt="Weekly Platform News: Preventing Image Loads with the Picture Element, the Web We Want, Svg Styles Are Not Scoped ">

Shaping the Future Web: The Web We Want

Browser vendors have launched "The Web We Want" (webwewant.fyi), an initiative to gather feedback from web developers. Submit your feature requests, and you might even get to present them at prominent industry events like An Event Apart or Smashing Conference!

Other Notable News

• Firefox's Hard Reload: Firefox now supports a non-standard boolean parameter for location.reload(), enabling forced reloads that bypass the browser cache. (via Wilson Page)
• Inline SVG Styling: A crucial reminder from Sara Soueidan: inline CSS within <svg></svg> elements is not scoped; styles bleed into other SVG elements. Be mindful of this global effect.
• XSS Auditor's Demise: Chrome's XSS Auditor, designed to detect cross-site scripting vulnerabilities, is being removed due to ineffectiveness. However, using the X-Xss-Protection: 1; mode=block header remains advisable for compatibility with older browsers. (via Scott Helme)
