RocketCake is a free web editor for creating responsive websites. For beginners and professional web developers.
Edit the website as it appears on your device. Switch at any time to view and editor it as on any other tablet, PC or mobile.
No need to learn any HTML or CSS. Just click, drag'n'drop or type. But of course, you are still free to mix in your own code, if you like.
The editor spits out clean HTML/CSS code. You also can use it as base for your more complicated websites or template for your server scripts.
Specify your own break points to adjust the website just as you like. The flexible break point editor makes it extremely easy.
