In the first part of this two part series, Rachel McCollin showed you how to create the settings and controls for a color scheme in the WordPress theme customizer. In this part, you'll use these to define CSS in the theme based on what users select using the customizer. You could easily take this further - perhaps by using radio buttons to provide layout options or by giving users a choice as to which colors from their scheme are used where. She would warn against making things too complicated though - in her opinion, the benefit of this approach is that it keeps things simple.
The theme customizer is a great tool to allow your users more freedom to tweak a theme without having to edit the code. But if you want to let your users change the colors of their site, things can get complicated. Adding a control for every single element they can change will make things cumbersome and users may end up with a site which looks like a garish mess.

A month later in April 2014, Econsultancy stated that global retailers are losing $3 trillion (USD) in sales every year from abandoned carts.
No one wants to ship buggy software. Ensuring that you release a mobile application of the highest quality requires much more than a human-driven manual quality assurance process. New devices and operating systems are released to the public each year. This means that there is an ever expanding combination of screen sizes and operating system versions on which you must test your mobile application. Not only would it be extremely time consuming, but attempting to test your iOS application by manual testing neglects an entire piece of the modern software engineering process, automated quality assurance testing.
History is always interesting, isn't it? In older versions of HTML, we had limited control over browser history. We could go back and forth using the available methods, but that was it. With the HTML5 History API, we have more control on playing with the browser history. For example, we have a way to add an entry in the history, or change the URL in the address bar without refreshing the page.
When building a website, you have a few ways to approach doing so. You can start by creating the most advanced version of the site with all of the scripts, styles, and so on, and then have it render in older browsers via graceful degradation, you may opt to ignore older browsers, or you can start with a basic page and add scripts and styles such that it becomes more functional via progressive enhancement.
