Elements not resizing properly when resizing browser window


        I'm getting really frustrated.  When I drag and resize the window of my browser the website elements, especially buttons and photos do not resize/shrink as I believe responsive elements should.  They all begin to overlap and get really ugly looking, until that is you reach a break point for a device, when you reach the breakpoint the elents then resize to what I set for each device. 

 How can I get these elements to start resizing properly when I resize my browser window?
