Cascadea is an extension for iOS that makes creating custom styles for any website effortless. It’s like having a personal style manager. You can just hover over any element on the page to instantly apply its pre-built styles. Moreover, you can create your own custom styles with just a few clicks of your mouse. The tool also comes with tons of styles, all organized inside a simple browser sidebar that can be customized to include more styles than shown.
Cascadea supports UserCSS styles using range and number variables, giving you even more options for configuring your styles. Whether you want to remove clutter from a busy site, make a custom dark theme for eye-catching view, prototype new CSS for a web app you develop, or just install styles that other people have made, Cascadea makes it easy to write, use, and share custom CSS.
With syntax highlighting, auto-completion, code folding, beautification, and more, it includes everything you need to write your custom CSS without needing a separate editor. Within a single style, you can also create sections with their own separate rules for which sites to affect, so one Cascadea style can contain unique CSS for different websites. All in all, superUserContent is a great tool that you can consider among its alternatives.
