Registration fields width not responsive

-- HikaShop version -- : 3.2.1
-- Joomla version -- : 3.8.2
-- PHP version -- : 7.1.7
-- Browser(s) name and version -- : CHROME
-- Error-message(debug-mod must be tuned on) -- : Field width not responsive

Hello,

The registration page is not really responsive, I already corrected the Hikashop Re Captcha V2 but this time the problem is coming from the fields,here is the page:

I use also hikamarket and it's working there:
The tags are different, dd dt on hikamarket and tr td on hikashop, I tried to modify some css, to add "tr.hikashop_registration_name_line.hikashop_registration_name_line { ...}" but no success.

Can you please take a look?

Best regards,
