I currently work with three queries always based on the minimum width and maximum width of the screen. The Mobile defines from 250px to 480px, the Tablet I put as 481px to 1023px and the Desktop I put it from 1024px.
Currently on the devices I tested are working with only small bugs that do not disrupt usage but friends and developers have reported problems when the site's responsiveness. The site is as follows:
This is a test domain, and I leave a NOTE, I have only the Cortana page ready, then click on the cortana circle a to see the body of the site.
The great doubt is being in the statement of these queries, do I have to declare it based on the same time? What is the best way to declare them? And in html, can I use some goal to help with this?
