Summary
We've covered a lot in this chapter. Everything from the basics of creating a page that validates as HTML5, through to embedding rich media (video) into our markup and ensuring it behaves responsively.
Although not specific to responsive designs, we've also covered how we can write semantically rich and meaningful code and considered how we might ensure pages are meaningful and usable for users that are relying on assistive technology.
By necessity, it's been a very markup heavy chapter so let's change tack now. In the next couple of chapters we're going to embrace the power and flexibility of CSS. First up, let's look at the power of CSS level 3 and 4 selectors, new viewport relative CSS units, and capabilities such as calc and HSL color. They will all enable us to create faster, more capable, and maintainable responsive designs.
