There’s a great new tool called CSS Pivot which actually allows you to add custom CSS to any website and share your changes via a link. This creates a very quick and simple way for website owners to get suggestions from web designers on how to improve the style of their website. CSS Pivot is very simple to use, all you need to do is visit csspivot.com, enter the URL of the site you want to suggest styles for then add your custom CSS styles via a small pop-up window. You can preview your changes at any time by clicking the “Preview” button and once you’re happy with your new style you can save it and you’ll get a short link that you can share.
You can only add CSS styles to websites which does make this tool quite limited. Being able to dynamically edit the existing style sheet of a website (like in Firebug) could be a more powerful solution. It’s an interesting idea that could come in handy next time your friend asks you “How can I improve my website styles?”
