Many of us created two versions of our websites back in the day; a regular desktop version and a mobile version. Using some fancy code, we pushed mobile devices to a m.version of our sites while everyone else went to the regular www.version. But with the advent of responsive sites, we need a way to move all our "m." users to the new, responsive site without breaking old URLs. Google has provided some guidance on doing that.

Browser vendors have made massive strides with JavaScript performance. Google kicked things off with its V8 engine, but since then, the likes of Mozilla and Microsoft have come back with snappy virtual machines of their own. But JavaScript can only take you so far.

You might be surprised what works and what doesn't, as Help Scout explains.

It was once the case that to do anything fancy with a web page, you needed a healthy dose of JavaScript. However, it's 2016 and HTML and CSS have come a long way. You might be surprised at what you can do without a single line of JS.
