How to increase the width of the 'other' checkbox field?

Hi Support,

Question: how do I get the user input box/field to grow wider? At the moment, it's way too short.

Thanks!

That specific field you can increase by adding the below CSS to your Custom CSS field:

input#input_21 {

    width: 250px;

}

If you need any further adjustments please let us know.

Thank you!
