Hey there,
Put your pair fields inside a <div> or <p> tag then wrap each in a <div> with a class of x-column x-sm x-1-2. It should look like this:
<div>
<div class="x-column x-sm x-1-2">
Your Name (required)
[text* your-name]
</div>
<div class="x-column x-sm x-1-2">
Your Email (required)
[email* your-email]
</div>
</div>
For the submit button, add the code in your Custom CSS
.wpcf7-submit {
color: #056839;
}
Thanks.
