I have already site key and secret key for reCaptcha . The link provided by you in reply is for WordPress . I am looking to put it in the html theme provided by you.
Please provide code for it.
You can assume following details to provide code (Note: it’s not real rCaptcha key.)
site key : nyxR3lxWmzUq8xR3lxWmzUq8
secret key : XypR6xWmzvq7xR3lCWxzwq7

Thanks for reply. But how to change the logo displaying during preloading i.e. preloader logo ? If I am using same code there , logo appears at left corner .
