min-width and max-width are the same

[cornernote]

Awesome post, really helps when looking up the query sizes.

One issue I noticed, you use the same value on min-width and max-width. I think the max width should be -1px.

For example. If my display is exactly 992 (Medium devices Desktops (≥992px))

the smallest size before going out of desktop mode:

@media only screen and (min-width : 992px) { ... }

the largest size before going to desktop mode:

@media only screen and (max-width : 991px) { ... }

What are your thoughts?
