Hi @aremun.
There is a spinner (icon that shows it’s busy) which is on the right side of the subscribe button. That pushes everything to the left.
If you know how you can add custom CSS to your site, you can use the following snippet:
span.wpcf7-spinner {
max-width: 0;
margin: 0;
}
If you do not, go to the admin bar – click customize – go to additional CSS – add the above mentioned snippet – click publish.
If you use Elementor Pro, here you can find some additional info:
