The shortcomings of our example

In this chapter we've covered all the essential component parts of a basic responsive HTML5 and CSS3 powered web page.

But you and I both know that this basic responsive example is rarely the limit of what we're tasked with building. Nor should it reflect the limit of what we are capable of building.

What about if we want our page to respond to different light conditions? What about changing the size of links when people use different pointing devices (a finger rather than a mouse for example)? What about being able to animate and move visual elements simply, using nothing but CSS?

Then there's the markup. How do go about marking up pages with more semantic elements; article, section, menu, and the like, or make forms with built in validation (no JavaScript needed)? And what if we want to change the visual order of elements at different viewports?

Let's not forget images. We have fluid images in this example but if people visit this page on a mobile phone, they will need to download a large graphic (2000px wide no less) that will only be shown on their phone at a fraction of that size. That will make the page considerably slower to load than needed. Surely there's a better way?

And what about logos and icons? We've used a PNG in this example, but we could easily use scalable vector graphics (SVGs) to enjoy graphics with resolution independence. That way they will look pin-sharp, regardless of the resolution of the viewing screen.

Hopefully you have time to stick around, as these are the very questions we will answer in the coming chapters.
