Contact form 7 label title and input field side by side

Hi there,

I have a question that how to let contact form 7 label title and input field side by side??

For example, I want to let it from attachment A to attachment B, how do I custom the CSS?

I took several methods but they are not working. ex: http://stackoverflow.com/questions/6526970/how-can-i-make-a-span-and-an-input-sit-next-to-each-other-and-collectively-take, here's the closer solution, but unfortunately, contact form 7 can't not custom div code which is important to this solution.

I can't provide my site due to private information if you can use a default contact form 7 to demo that will be better.

Thank you.

Best regards,
