Can you have more than one primary button on the page?
Don't have more than one primary action button on the screen at a time. Let users focus on the task at hand. You can have more actions on the page, but make sure there is only one primary. Users have expectations of what a single button on a page will do, based on the page they are on.
How do I put a button side by side in HTML?
If you have multiple buttons that should sit side-by-side on the same line, add the data-inline="true" attribute to each button. This will style the buttons to be the width of their content and float the buttons so they sit on the same line.
