html - How to center a button WITHOUT a div using CSS -

i trying center button without div. button follows

<body>   <button>some text</button> </body>

i have tried using few different techniques such as:

text-align: center

and

margin:0 auto;

but these don't work.

its simple, make display block element:

<body>   <button>some text</button> </body>  button {     display: block;     margin: 0 auto; }
