In this chapter, we started our first project. Earlier in the chapter, we explored the Responsive.gs components, looked into how Responsive.gs constructs a responsive grid, and what classes are used to shape the grid.

We also discussed HTML5, including the new elements, namely, the polyfills to mimic HTML5 features in the browsers that do not support particular features natively. Then, we used HTML5 to construct the blog markup.

In the next chapter, we will be focusing more on marking the blog up using CSS3 and adding some JavaScript. We will also be debugging the blog for errors that turn up in old Internet Explorer.
