Hi, Bucky. I love your html 5 tutorial - I have learnt a lot from it. I have tried to get it to work with other browsers as your tutorial, focused on chrome. ICould you tell me if the following code is good as I am getting strange results and I don't want to take your time, going into details.

My objective is to try and get the flex box to work on the other browsers. Thanks

body{
width:100%
display:~webkit-box;
-webkit-box-pack: center;
display:~moz-box;
-moz-box-pack: center;
display:~ms-box;
-ms-box-pack: center;
display:~o-box;
-o-box-pack: center;
}
#big_wrapper{
max-width: 1000px;
margin: 20px 0px;
display:-webkit-box;
display:-moz-box;
display:-ms-box;
display:-o-box;
-webkit-box-orient: vertical;
-webkit-box-flex: 1;
-moz-box-orient: vertical;
-moz-box-flex: 1;
-ms-box-orient: vertical;
-ms-box-flex: 1;
-o-box-orient: vertical;
-o-box-flex: 1;
}
