How to replace input type="submit" to button on Contact Form 7?

Hi,

Could you please write what is the most recommended and best way to replace input type=”submit” generated by [submit] to button element.

From:

<input type="submit" value="Submit" class="wpcf7-form-control wpcf7-submit" />

To:

<button type="submit" class="wpcf7-form-control wpcf7-submit">Submit</button>

The reason is that with current markup it’s not possible to use the :after pseudo-element on input?

Thanks!
