My problem is that when I use Windows snap feature to the edge of the screen (so you can get two equal size windows on either side), my text and containers are not responding to the new size properly, and some the text is missing. I find this annoying and I imagine my readers will too. Any advice would be very appreciated. I love your parabola theme by the way, keep up the good work!
Responsiveness is meant for mobile devices, not resized windows.
If you resize your browser to a smaller than 800px width, responsiveness kicks in; otherwise, you see the desktop (full width) version of the site.
