Button

Sorry, I am a bit confused.

Are you saying you want the button to read

Hello
There

or is there something else.

If as above I know of no way this can be done with the input type button.

Even if you set the height and width of the button it will not wrap the text.

You could however possible create your own button by using a table with borders and based on mouse down and up change the edge shading to make look like a real button.
