html - cannot center align canvas -

-

i have been googling solutions no avail. want center-align canvas. have tried float="center", text-align="center", margin-top: 100px stage didnt align center in browser. appreciated.

<body onload="main();"> <canvas id="shooter" width="320" height="480" align="center"> browser not support html5 canvas tag. </canvas>

you center align by:

#shooter {   margin: auto;   display: block; }

make sure parent container have 100% width.
