Hi, because of changes to our company I have recently become the web developer again. I enjoy web development, however, when I take 3-5 year breaks, I get rusty. Plus, things change, and new things that I am not up to speed with emerge. This time I have discovered that it a good idea to use Flexbox for responsive design. It looks like some great stuff. However, I am curious to know if I should really let this be what I rely on for a responsive site. Are there cons to working with Flexbox layouts? Thanks
