Dark Mode is all the range with desktop and mobile OS’es right now. Interestingly, modern browsers can detect the OS dark mode preference, and use a different set of CSS styles respectively for light or dark modes! Here’s how I updated My custom Grav theme.
Lots of web pages now rely on SVG instead of PNG or JPG images. SVG stands for Scalable Vector Graphics, an XML-based vector image format that scales well, unlike bitmap images (bitmaps become pixelated when up-sized). I recently wanted a quick way to convert a SVG to PNG, and discovered modern browsers (read: Chrome and Firefox) can do this with a simple bit of code.
