title: flex-wrap property not working on mobile screen
body: <p>I need help if anyone can help . I am having flex-wrap property not working on mobile screens but it works fine when i shrink my browser width. Toggling device toolbar doesn't allows wrap property to work. I need this for my upcoming project and its important. Please help me (see attached screenshots url i have uploaded) </p>
