I have a mobile-only HTML contact form divided in source code into three sections; each section should contain fields by a different context.
```html
<!DOCTYPE html>
<html>
~~<head>~~
~~<title>contact_us</title>~~
~~<meta charset="utf-8">~~
~~<link rel="stylesheet" href="contact_form/frontend/contact_form.css"></link>~~
~~</head>~~
~~<body>~~
~~<div id="form_parent">~~
~~<form id="contact_form" class="contact_form" action="contact_form/backend/contact_form.php" method="POST">~~
~~<div id="form_child">~~
~~<section>~~
~~~~
~~<section>~~
~~~~
~~<section>~~
~~~~
~~</section>~~
~~</section>~~
~~</section>~~
~~<div><input type="submit" value="Submit" id="submit" class="submit"></input></div>~~
~~</div>~~
~~</form>~~
~~</div>~~
~~</body>~~
</html>
```
In mobile it would appear just as a single columned long form but I think to change the form from mobile-only to mobile-first so that above say 992px the three sections would appear in three different columns and the submit button would appear with 100% width under all of them; with the power of `@media screen and (min-width: 992px) {/* Code */}` I would get something like:
```
|----------| |----------| |----------|
| Column 1 | | Column 2 | | Column 3 |
|----------| |----------| |----------|
|------------------------------------|
| Submit |
|------------------------------------|
```
~~How would you suggest to achieve that goal with modern CSS?~~

Modern CSS for splitting form sections into columns

I have a mobile-only HTML contact divided in source code into three sections; each section should contain fields by a different context.

```html
<!DOCTYPE html>
<html>
	<head>
		<title>contact_us</title>
		<meta charset="utf-8">
		<link rel="stylesheet" href="contact_form/frontend/contact_form.css"></link>
	</head>
	<body>
		<div id="form_parent">
			<form id="contact_form" class="contact_form" action="contact_form/backend/contact_form.php" method="POST">
				<div id="form_child">
                                    <section>
                                        <!-- FORM FIELDS -->
                                        <section>
                                            <!-- FORM FIELDS -->
                                            <section>
                                                <!-- FORM FIELDS -->
                                            </section>
                                        </section>
                                    </section>
                                    <div><input type="submit" value="Submit" id="submit" class="submit"></input></div>
				</div>
			</form>
		</div>
	</body>
</html>
```

In mobile it would appear just as a single columned long form but I think to change the form from mobile-only to mobile-first so that above say 992px the three sections would appear in three different columns and the submit button would appear with 100% width under all of them; with the power of `@media screen and (min-width: 992px) {/* Code */}` I would get something like:

```
|----------| |----------| |----------|
| Column 1 | | Column 2 | | Column 3 |
|----------| |----------| |----------|
|------------------------------------|
|               Submit               |
|------------------------------------|
```
