Google Web Designer 

Google Web Designer lets you create interactive HTML5-based designs and motion graphics. It can be used for designers and developers alike. In this respect, although it does not require working with code, it also allows editing HTML, CSS and JavaScript. Fortunately, you do not need to start from scratch as there are multiple templates to choose from. Besides, there are tutorials to teach you the basics.

The application has a carefully designed interface. As said before, you can use the WYSIWYG Design view to focus on the visual aspects. Moreover, it is possible to switch to Code view to customize the element a little further. One of the best features of this tool is that it supports fluid layout, which means that any element inside a container is automatically resized without changing the overall layout.

Google Web Designer comes with a lot of ready-made components. But it does not stop there, it is even allowed to create new components from scratch or modify existing ones. In terms of interaction, good news is that you can assign actions to any element. Again, although their code is generated automatically, you can customize actions to meet your needs. Finally, the tool supports creating animations in CSS3 and HTML5.

All in all, Google Web Designer is certainly a good choice for web designers and developers. However, you should be alerted that, rather than creating entire websites, this tool is intended for designing various types of elements. Even though it integrates with DoubleClick Studios, this application cannot import HTML files from third-party design tools. The product definitely deserves a try, and luckily it is absolutely free.
