I try, but after my style CSS don’t work:

[text* your-name id:contact-form-height-field default:user_first_name placeholder “…”]

CSS:
#wpcf7-f5021-p2627-o1 .idcontact-form-height-field input[type=”text”] {height: 30px;}

Thanks

hmmm… that don’t work with your solution.

I find a solution:

[text* your-name default:user_first_name placeholder “…”]

CSS:
#wpcf7-f5021-p2627-o1 .your-name input[type=”text”] {height: 30px;}
