Custom CSS: On the mulltiple choice, can you enlarge the area for the option?

I am creating a form where I need to list different options where they can pick more than one. However, because there are two options on a row, the first option is limited in length. Can that be extended or is there a better setting to use.

Form Revive '17 Live Stream is the one in question.

Please inject the following CSS to your form.

.form-multiple-column {

    width: 100%;

}

.form-checkbox-item {

    width: 50% !important;

}

Please see steps below.

Result should be as follows.
