Once you’ve successfully installed reCAPTCHA on your site, we can turn it from a standard reCAPTCHA style into a transparent style.
You can apply CSS styles to the reCAPTCHA widget to change its colors and other visual properties. This way it looks more neutral, unlike the standard one, by giving it a better look and feel for your website page. This method works by setting the reCAPTCHA theme to “clean”, then adding in the inline styles within the page at the very end, so it loads last.
Use the “!important” directive in your CSS, so that when you call it in your CSS, it won’t matter because it’s usually the last call. Put the styles within the HTML directly on the page, at the end, this makes it the last reference and those styles will be applied.
At the end of all this, it should be transparent and look like the picture below.
