Thank you for your help, the number of places where my web page breaks are fewer. I have checked my page in Firefox, Internet Explorer Edge, and Chrome browsers and I noticed that the page still breaks.
In Chrome the web page breaks when the page width is between 962 and 968 pixels. In Firefox and Chrome, the page breaks at other page widths.
I tried adding 5 more pixels to the media query breakpoints but that didn’t help.
