Reply To: WordPress – Media Queries not working

[webinuse]

It’s cascade style sheet so your media queries have to go to the absolute bottom. The other reason why they may not work properly is that you are using (max-width: 1000px) and the plugins (skeleton, etc) are using (min-width: 1000px); next thing is you have to check that your queries are written in order (from bottom) from smallest to biggest. As far as your header is in question I can not find anything wrong.
