Hi guys, I am building a new website on HTML (I just took a template and modifying it by myself). Now, I want to implement a contact form in one of my service landing page. I am going to use adwords for my services. So if someone clicks on my ads and lands on my page and then fills in contact form I will get his/her details in my email. So can you please help me to build up a contact us form that will have 4 fields (name, phone, email and message) with validation check?
