How to style Contact Form 7 form’s HTML

You can copy and paste this code below into the Form’s editor eg: https://d.pr/i/DmbNKw and as seen in that screenshot, you can add as many fields as you want.

<label> Your Name (required)</label>
    [text* your-name]
<label> Your Email (required)</label>
    [email* your-email] 
<label> Your Message</label>
    [textarea your-message] 
[mc4wp_checkbox "Please keep me updated on events, new products or new collections."]
[submit class:btn class:btn-primary "SEND MESSAGE"]

What’s different from the default form.

1. Labels don’t contain the actual input.
2. The [mc4wp_checkbox .. ] shortcode which generates a checkbox to subscribe into MailChimp. Needs MailChimp for WP plugin.
3. Submit button contains 2 css classes, btn and btn-primary. More about CF7 tags and attributes .
