back end php and css code fixing on request form

Hello I have here some simple code fixing tasks on form of my site. Most of the job is done, need professional who will fix some issues and finish coding. tasks with request form on my site, html css coding is finished, need to be done some php backend jobs, and css fixing: Php coding: 1. There is request form on website, capcha modul is implemented on the level of html and css, need to add php coding on processing file(this file also programmed and working for other parts of form) and make this captcha work. i will give you instruction for back end coding for this captcha from provider of captcha. 2. After successful filling or in error cases processing php redirects user to middle page to inform about it and then to thank you page. Need to be done that it redirects to thankyou page directly, and if errors on form filling by user inform user about it on popup window, and don’t let go through. Css coding: 1. country Select field looks different from other fields, I styled it with css, but I think there is some error may be. 2. Two margin corrections: Move button “submit” to right to 15px, add some margin after topic of form. 3. Font fixing, I have added css for loading my choosed font for website and created font folder, but it looks like it is not working as on other browser, website shown with secondary fonts.
