View Demo. ish. is yet another viewport resizer. What's with the name, you ask? Small-ish. Medium-ish. Large-ish. That's the idea. Many have long been preaching to let content, not device widths determine breakpoints in responsive designs, so rather than determining several fixed breakpoints, ish. roughs out general ranges in order to better serve the entire resolution spectrum.
Do we really need another viewport resizer? After all, there's no fewer than 19 viewport testing tools out there already.
The real reasons for this tool is to educate and to facilitate a mental shift. Many clients, designers and developers get hung up on specific device widths, which is why this tool doesn't include any such language, device chrome or anything like that. Ish. helps keep everyone focused on making a design that looks and functions great at any resolution.
Who is this for? Clients. Visual designers. Developers. Really anyone involved in the project that needs educated about creating truly device-agnostic websites.
You can find the project on Github. You should set up ish. on your own server or dev environment for best results.
