want to show the button in one line

Hello,
As I read you had a difficulty to add your button in a line There are too many processes to do it.
But the best and easiest method is to do it via CSS code
First, you have to prepare a list as a class like this.

<form method="post" action="nextPage.html" name="nameForm" style="display:inline;">
<input type="hidden" name="value" value="someValue">
<input type="submit" name="submit" value="Submit">
via this code you can do multiple button is a list.
Hope this helps you.
Thanks
